The Flash Talk Podcast - THEFLASHTALK

After an unexpected guest from the future, Nora West-Allen, appears at their home, Barry and Iris must figure out how to get her back to the future without disrupting the timeline, even more than she already has. Team Flash must work together to send Nora back, while simultaneously fighting off another villainous meta.

Earth-2 Wells is captured while running through the woods. Jesse explains that he was leading an expedition to Gorilla City that was ambushed and killed while Wells disappeared. Barry recalls that in the future Central City will be attacked by gorillas. He, Julian, Cisco, and Caitlin go to rescue him but are captured by Grodd. Speaking through Wells, Grodd asks Barry to help him usurp his master Solovar. Barry agrees to fight Solovar in the arena for the lives of the others and wins, but refuses to kill him. Grodd seizes control of Gorilla City and prepares an invasion of Earth-1. The team asks Caitlin to kill Cisco so Grodd can't open a portal, but she refuses. Barry fakes his death and Grodd removes him from his cage. He resuscitates himself and frees the others, and they return to Earth-1. Jesse and her father reunite and Wally and Jesse recommit to their relationship. Julian asks Caitlin out on a date. Grodd assembles his army with a brainwashed Gypsy at his side.

Barry and Wally continue their training in order to save Iris from Savitar. They race against each other, and Barry wins by phasing through a building. Julian finds a decayed corpse that was murdered just eight hours ago. He informs Joe that this is surely the work of a metahuman. The body is taken to S.T.A.R. Labs for investigation, where Caitlin and Julian observe it turning to ash. Iris confesses to Barry that she is afraid of her future. The meta responsible for the disintegrated corpse attacks Joe and is revealed to be targeting the police who arrested him in Flashpoint. The metahuman tries to disintegrate a bridge on the train Joe is on, forcing Barry to phase the train through the wreckage of the bridge. Barry teaches Wally how to phase, which Wally uses to expose the meta to his blood and strip him of his powers. Joe insists that everyone be honest with him from now on after learning of Iris's future death. While practicing phasing, Wally is shocked to see Jesse coming through a portal. Jesse says her father has been abducted by Grodd and taken toGorilla City.

An Earth-19 bounty hunter named Gypsy, possessing powers similar to Cisco's, arrives on Earth-1 intending to take H.R. back to Earth-19 for trial and execution, as inter-dimensional travel is forbidden there. Cisco demands a trial by combat for H.R.'s life, which she accepts. As the duel is to the death, Barry and H.R. try to ambush Gypsy to save Cisco, but she easily defeats them. Meanwhile, determined to leave a legacy, Iris persuades Wally to help her bust an arms dealer. While he is out scouting, she confronts the dealer, seemingly unafraid of death.

Barry has been having nightmares about Iris's murder. Jared Morillo attempts a robbery, but is confronted by Barry, who recalls a news report during his visit in the future when the latter captures the former. The distraction allows Morillo to overpower Barry and escape. H.R. launches the museum, but no one visits it. In a second confrontation, Wally intervenes and captures Morillo, gaining praise by everyone except Barry. He eventually reveals the future he saw to everyone but Joe. The team decides to change the course of other events in order to prevent Iris's death. Using Cisco, Barry accesses the future memory, in which the news reveal that the S.T.A.R. Labs museum will close and Caitlin will become Killer Frost. Morillo escapes, and Barry decides to change the first event by letting Wally capture him. Cisco relaunches the museum, starting with an exhibition for elementary school students. Julian is persuaded by Caitlin to join the team. A mysterious woman from another Earth arrives, searching for H.R.

Barry asks Jay Garrick for help against Savitar. The two heroes locate and defeat Alchemy and return his weapon to its box, causing Savitar to disappear before it can kill Jay. Discovering Julian to be Alchemy, Barry reveals his own identity to him to get further information. Julian relates how he located the Philosopher's Stone following a vision of his dead sister, and that he has been having blackouts ever since. Savitar manifests through Cisco using visions of Dante and fights Barry and Wally, but Caitlin manages to convince Cisco to close the box again. The team communicates with Savitar through Julian, who claims that Barry, in the future, will imprison him. He also says that one teammate will betray them, another will "fall", and a third will suffer a fate worse than death. Trying to end Savitar's threat, Barry and Jay throw the box into the Speed Force, but in the process, Barry is thrown five months into the future and witnesses Savitar killing Iris. Jay advises Barry that the future is not fixed. Wally is given his own "Kid Flash" uniform, Julian gets Barry's job back for him, and Barry rents a new apartment for him and Iris.

Barry investigates a meteor crash outside Central City that turns out to be a spaceship from which aliens emerge. Lyla tells the team that the "Dominators" landed previously in the 1950s, but then mysteriously departed. Needing help, Barry assembles the original Team Arrow, Thea, the Legends, and Supergirl of Earth-38. The team begins training at a S.T.A.R. Labs facility, sparring against Supergirl to prepare against the aliens. Cisco finds and reveals a message to Rip Hunter from Barry's future self, which exposes Barry's manipulation of the timeline and how it affected other team members. Oliver, Supergirl, Felicity, Martin and Jefferson become the only ones who still trust Barry. The Dominators abduct the President. Supergirl leads most of the others in a rescue effort, but the Dominators kill the President and trap them with a mind control device. The controlled heroes return and attack S.T.A.R. Labs. While Oliver holds them off, Barry lures Supergirl to the device and manipulates her into destroying it, freeing everyone. The team decides to trust Barry again. Suddenly, Sara, Ray, Diggle, Thea, and Oliver are teleported away before Barry can intervene. This episode begins a crossover that continues on Arrow season 5 episode 8 and concludes on Legends of Tomorrow season 2 episode 7.

Savitar opts instead to race Barry across the city, then batters him to demonstrate its superiority. Cisco and Caitlin arrive and rescue Barry, but Savitar flees. Caitlin, with a Killer Frost aspect having taken over, violently interrogates one of Alchemy's followers at CCPD headquarters, then abducts Julian and coerces him to find other acolytes, in order to find Alchemy and have him remove her powers. Barry and Cisco track her down and imprison her, but the team is fractured after she reveals Barry's role in Dante's death by creating "Flashpoint". Greatly concerned and disregarding the consequences, Joe breaks Wally out of the cocoon. Wally emerges with unmanageable speed powers and he races away in a confused state. Barry offers his life to Caitlin for her freedom in a successful attempt to restore her sanity and gain her help in treating Wally. Joe and Barry locate Wally and stabilize his condition with Caitlin's serum, and Wally soon embraces his new abilities. Julian forces Barry to resign from the CCPD in exchange for him protecting Caitlin from the police. Julian is later revealed to be unwillingly working for Savitar as Alchemy.

When Wally relates his recent dreams of being Kid Flash, Barry reveals what happened to him during "Flashpoint". A metahuman H.R. nicknames "Shade" appears and murders a stockbroker. Caitlin reveals her powers to Cisco and has him "vibe" her to know her future. Cisco sees himself fighting Killer Frost, causing Caitlin to contemplate leaving for good. Alchemy begins summoning Wally to him, so the team locks him in the particle cells for his own safety. Meanwhile, Barry and the others stop Shade's next attack and capture him using meta-dampening handcuffs. Cisco tells everyone the truth about Caitlin, and Barry privately confesses to her that her powers came from him creating "Flashpoint". Wally volunteers to lead the team to Alchemy to capture the villain and stop the memories, which are physically injuring him. Barry, Joe and a S.W.A.T. team locate Alchemy and his followers and surround them. Another speedster, which only Barry can see, suddenly attacks them. As Barry fights it, Alchemy entices Wally to pick up his fallen energy weapon, which encases Wally in a crystal cocoon. Calling itself "Savitar", the speedster overpowers Barry and prepares to stab him.

Without informing the others, Caitlin visits her estranged mother, Carla, at her medical research company to have her powers examined, but leaves after viciously attacking another scientist who intended to exploit her condition. Meanwhile, a gigantic creature repeatedly appears and disappears on the streets of Central City. Cisco grows suspicious of the newly-recruited "H.R." Wells when he does not provide much help in battling the monster. The monster is revealed to be simply a hologram operated by a bullied 15-year-old boy wanting to create fear in others. Barry exposes the deception in time to keep police snipers from harming civilians, and prevent Julian from shooting the boy, whom he mistakes for a metahuman. H.R. is revealed to have no technical knowledge at all. He admits that he is only an "idea man" for his tech company on Earth-19, and that he came to Earth-1 primarily to get material for a novel. The team decides to give him a chance to prove his worth as an assistant. A badly shaken Julian reconciles his differences with Barry. Carla informs Caitlin that her powers are increasing and that she needs to stop using them, or her condition will become irreversible.

Three years ago, Sam Scudder and Rosalind Dillon, former cohorts of Leonard Snart, were caught in the original particle accelerator explosion. In the present, Barry begins training Jesse on how to use her powers. Wells suggests the team locate a doppleganger of his from another Earth to replace him on the team once he and Jesse leave. Scudder returns from being trapped in a mirror-like dimension with the ability to transport himself and others through reflective surfaces. He reunites with Dillon, who now has vertigo-inducing powers, and they go on a crime spree. Barry and Jesse (as "Jesse Quick") confront them but are defeated, and Barry ends up trapped inside a mirror by Scudder. Caitlin secretly uses her emerging ice powers to help Barry free himself from his predicament. He and Jesse then successfully capture Scudder and Dillon. After evaluating the candidates, the team recruits the friendly and eccentric Wells of Earth-19, despite the Earth-2 Wells' misgivings. Jesse and her father then return to Earth-2, with Wells apprising Cisco about Barry's suspicious escape. That night, Caitlin accidentally freezes the water in her shower and her appearance begins showing signs of her Earth-2 doppelgänger, Killer Frost.

Wells and Jesse return to Earth-1, where she reveals she has gained super speed from the second dark matter blast. Wells hopes everyone will dissuade her from using her powers. Elsewhere, foster child Frankie Kane develops metahuman magnetic powers that manifest as an alternate personality, Magenta, who attacks her abusive foster father. Julian confronts Frankie at the station and is nearly killed by Magenta. Barry learns from Magenta that she got her powers from Alchemy. She escapes and later goes to the Central City Hospital to kill her foster father by dropping an oil tanker on the building. Barry creates a vortex to hold the tanker in place, but is unable to confront Magenta simultaneously. Wells sends Jesse to help. She takes over the vortex while Barry talks Kane into gaining control over Magenta. Wally, grappling with disappointment over having no speed, realizes he is also having dreams from "Flashpoint". Wells tells Jesse that he will support her decision and presents her with her own speedster costume. Joe later shows Barry and Julian footage of Clariss being killed in his cell by an unseen force, manifesting only a flying ball of white light.

Barry learns of multiple changes to the timeline: Iris has not forgiven Joe for concealing that her mother was alive, Cisco is angry with him for not altering the timeline to save his brother Dante from being killed, and he has a new CSI partner, Julian Albert, who does not like or trust him. Barry decides to travel back to fix the damage, but he is intercepted by Jay Garrick. Jay tells Barry that the timeline never resets exactly and he has to learn to live with his mistakes. Meanwhile, Clariss has visions of "Flashpoint" and locates the person responsible, Alchemy, who restores Clariss' powers and full "Flashpoint" memories. Barry tells the team about the timeline's alterations before confronting Clariss at an abandoned warehouse. Alchemy is there as well, saying that he is "preparing this world" for a future event. Cisco arrives and helps Barry defeat Clariss, who is then incarcerated in Iron Heights. The team determines Alchemy is creating other metahumans from "Flashpoint" whom they need to track down. Cisco and Barry reconcile, as do Iris and Joe. Caitlin is secretly revealed to have gained cryokinetic powers. Barry and Iris begin dating, while Clariss is killed by an unseen creature with a metallic arm in his cell.

After preventing the murder of Nora Allen, Barry returns with Eobard Thawne to the present and imprisons him in a cage that dampens his speed. In the new timeline, which Thawne dubs "Flashpoint", both of Barry's parents are alive; Joe has a poor relationship with Wally and Iris and is chronically in trouble at work; Cisco is a billionaire tech magnate; and Caitlin is a pediatric ophthalmologist. There is also a new Flash in Central City called Kid Flash struggling with his own nemesis, Edward Clariss, known as "The Rival". Barry begins losing his memories of the original timeline due to the new timeline becoming permanent. After discovering Kid Flash is Wally, Barry teams up with him and stops Clariss, but Wally is critically injured in the process. Realizing that the new timeline is worse for those closest to him, Barry is forced to let Thawne return to the past and kill Nora, resetting the timeline and restoring Barry's memories. Back in the present, Barry learns that the timeline did not reset exactly. Meanwhile, Clariss is confronted by a mysterious voice and finds the message "Alchemy" being scratched into his mirror by an invisible force.

Zoom comes to Barry and demands a race to determine who is faster, threatening to kill everyone Barry loves if he refuses. Wells realizes that Zoom stole a magnetar from Mercury Labs that will allow him to destroy every world in the multiverse if he and Barry can create enough energy from their race to power the device. When Barry refuses to back out, the team locks him in a containment cell for his own protection. The team develops their own successful plan to send Zoom back to Earth-2, but Joe is pulled in with him. On Earth-2, Zoom reveals to Joe that the man in the iron mask is the real Jay Garrick. Wally releases Barry to rescue Joe. Barry agrees to race Zoom if he returns Joe unharmed. As Barry and Zoom race, the magna tar begins to charge. However, Barry creates a time remnant of himself, who gives his life to stop the magna tar, while Barry takes out Zoom. Defeated, Zoom is then taken away by the Time Wraiths. The true Jay Garrick is revealed to be Henry's doppelgänger, which distresses Barry. Wells and Jesse return with Jay to Earth-2. Still feeling broken and defeated, Barry travels back in time and stops Reverse-Flash from killing his mother.

Zoom's metahuman army wreaks havoc across the city. Barry puts out several fires and takes out some of the metahumans to help the police. Back at S.T.A.R. Labs, Barry displays a level of confidence in stopping Zoom that concerns the team, and each of them attempts to convince him to be more cautious. Caitlin returns to the team, but not without emotional trauma from being kidnapped. A metahuman begins attacking various buildings around Central City using a sonic blast. Barry confronts the metahuman, who turns out to be Laurel Lance's doppelganger, "Black Siren". She initially gets the upper hand, but Barry is rescued by Wally, who is trying to help out in order to repay the Flash. The team creates a sonic amplifier tuned to the frequency of Earth-2 natives. They discharge it and render all Earth-2 metahumans unconscious, allowing Barry to apprehend them all at once, although Zoom escapes. Later, Zoom returns and kidnaps Henry in front of the team. Barry races after them, revealing his identity to Wally, and is forced to watch Zoom kill his father.

Jesse and Wally are found unconscious; Wally recovers, but Jesse remains in a coma. Meanwhile, Cisco has a vibe of Barry and realizes that he is still alive. Barry wakes up in his own bedroom and finds "Joe" downstairs. "Joe" explains what he really is: a physical manifestation of the Speed Force. "Joe" informs Barry that he cannot leave unless he catches a mysterious moving figure. Cisco and Wells create a path into the Speed Force so Barry can escape, but Barry chooses to remain so he can earn his powers back. As he pursues the figure, other Speed Force entities challenge Barry on what it means to be a hero, and how he cannot become the Flash again until he finally accepts his mother's death. Barry shares a moment with his "mother", which allows him to finally catch the moving figure—himself. His powers restored, and with help from Cisco and Iris, Barry returns to S.T.A.R. Labs to save the team from the reanimated corpse of Tony Woodward. Afterwards, Barry uses speed force energy to bring Jesse out of her coma. Across town, Zoom has assembled a metahuman army, which he plans to unleash on Central City.

With Barry powerless, the team rigs a hologram of the Flash to stop crime around the city so that no one will know the truth. Wells again proposes recreating the particle accelerator explosion. Barry goes to his father, Henry, for advice, who returns with him back to Central City. Henry argues with Wells over his procedure for returning Barry's powers, concerned for his son's safety. Zoom and Caitlin arrive back on Earth-1, with Zoom declaring the city under his control. The Earth-2 version of Dante Ramon, "Rupture", arrives on Earth-1 looking to kill Cisco for killing his Earth-2 brother. Zoom sends Rupture after the police to send the city a message. Barry and the police stop Rupture, but Zoom arrives and kills the officers himself, and Rupture for failing. He then publicly announces the Flash's disappearance. Realizing that he cannot stop Zoom without his powers, Barry agrees to Wells' plan. During the process, Barry is seemingly vaporized, while Jesse and Wally are caught in the blast.

As Barry adjusts to life without his powers, Wells decides to leave the lab to look for Jesse. Shortly after speaking with her, Wells is attacked and kidnapped by Griffin Grey, who demands that Wells find a cure for his metahuman abilities. Grey has superhuman strength, but he is also aging rapidly. Barry discovers that when Grey uses his super strength, he accelerates the aging process. Barry, Joe, and Cisco manipulate Grey into exerting his powers until he ages and dies as a weak, old man; his body then reverts back to its 18-year-old self. To fight Zoom, Wells offers to recreate the circumstances that gave Barry his speed. On Earth-2, Hunter tells Caitlin that he kidnapped her because he is in love with her. Caitlin encounters her doppelgänger, Killer Frost, who was captured by Zoom. Frost convinces Caitlin to help her escape, but then attempts to kill her. Zoom arrives and kills Frost, then warns Caitlin not to free the man in the iron mask. Later, Zoom decides to conquer other the Earths in the multiverse, and he takes Caitlin with him back to Earth-1.

Years earlier on Earth-2, a young Hunter Zolomon watches as his father murders his mother and is subsequently sent to the local orphanage. In present day, Barry tests the tachyon accelerator and is able to enhance his speed four times greater than normal. Barry decides to re-open a breach back to Earth-2, and he believes that Cisco's powers are the key to opening the portals. Meanwhile, Wells recounts how the particle accelerator explosion on his Earth created Zoom. Zolomon was a convicted serial killer as an adult, who was receiving electroconvulsive therapy during the explosion, during which he received his powers. Cisco opens a breach and Zoom immediately comes through, chasing Barry back to S.T.A.R. Labs. There, Barry uses images of Zoom's parents as a distraction to trap him, but Zoom manages to escape, claiming to be "the darkness". Zoom kidnaps Wally and demands Barry's speed in exchange for Wally's life. Barry agrees, so Wells siphons all of his speed force, leaving Barry powerless. Zoom injects the speed force into himself, and he kidnaps Caitlin with his enhanced speed, before escaping.

Barry travels back in time to when Hartley Rathaway attacked the team, and changes places with his past self in order to have Dr. Harrison Wells/Eobard Thawne help him solve the Speed Force equation. However, after a Time Wraith follows Barry to the past, Eobard deduces Barry's deception and attempts to kill him. Barry is able to convince Eobard that his plan succeeds in the future, but that in order to maintain it, he must help Barry become faster. The wraith comes to the lab, where Caitlin and Cisco are forced to accept help from a captured Hartley to deter the wraith. Afterward, the Barry from the current time arrives, forcing an explanation of the time travel event. Eobard provides the future Barry with the information needed to solve the formula, so that he can return to his time. Before he leaves, Barry tells Caitlin and Cisco to find a way to stop the wraith. As Barry prepares to make the jump through time, the wraith arrives, which forces the past timeline's Barry to intervene, so that his future self can return. Back in his time, Barry is confronted by the wraith again, but a reformed Hartley arrives with his sonic gauntlets and defeats the wraith.

Trajectory arrives in town intent on creating maximum chaos. Trajectory's antics are misinterpreted as having been perpetrated by The Flash himself. Barry must thus act quickly to uncover the mystery of who is causing damage in which others think it is him, and what may be driving their mad desire for speed and destruction.

Wells, Cisco, and Barry agree not to discuss what happened on Earth-2 for fear of repercussions. While everyone tries to move on, the humanoid shark-monster that Wells stopped, known as "King Shark", escapes A.R.G.U.S. custody and heads for Central City to kill the Flash. John Diggle and Lyla Michaels arrive to warn Barry, which prompts him to look for King Shark and put a stop to him for good. Barry teams up with Diggle, Lyla, and the rest of A.R.G.U.S. to track King Shark, but he shows up at Barry's home looking for the Flash, tracking Barry's electrical field. A.R.G.U.S. arrives and forces King Shark to retreat. The teams attempt to trick King Shark into a trap, but the bait does not work. Barry forces King Shark to chase him out on the water, and when he is far enough he creates an electrified, underwater cyclone that subdues King Shark and allows A.R.G.U.S. to imprison him again. Later, Barry vows to open a breach back to Earth-2 to stop Zoom. Back on Earth-2, it is revealed that Zoom's real appearance looks exactly like Jay.

Zoom realizes that Dr. Wells has returned to Earth-2 and issues a demand to the citizens of Central City to locate him. Zoom attacks S.T.A.R. Labs looking for Wells and Cisco, but they manage to escape with the Earth-2 Barry. Wells, Cisco, and Barry update Iris on what happened with the Earth-1 Barry, so they all set out to find Killer Frost in the hope that she will lead them to Zoom. After a fight, Killer Frost agrees to take the team to Zoom. The team arrives to rescue Barry and Jesse, but Zoom shows up too. The team is able to escape while Killer Frost keeps Zoom frozen and unable to move, but a third, unidentified prisoner is left behind. On Earth-1, Caitlin creates "Velocity 9", a compound to temporarily give Jay his speed so that he can stop a new metahuman named Geomancer. After, Caitlin discovers that when Jay uses Velocity 9 the serum starts to cure his illness. Jay, Caitlin, and Joe stabilize the breach and allow Barry, Cisco, Wells, and Jesse to return, but not before Zoom pulls Jay back through the breach to Earth-2.

Before heading to Earth-2, Barry closes all but one of the breaches so that Zoom has no other way to travel between the parallel Earths. Using the last breach at S.T.A.R. Labs, Barry, Cisco, and Dr. Wells travel to Earth-2, but there is a surge of energy that de-stabilizes the breach. The trio will be stuck in Earth-2 until Caitlin and Jay can stabilize the breach again. Barry decides to impersonate his Earth-2 self to get more information on Zoom. Barry is attacked by Earth-2's Caitlin and Ronnie Raymond, known here as Killer Frost and Deathstorm, agents of Zoom. Cisco attempts to help the police stop the pair, but he is confronted by his own evil doppelganger, "Reverb". Barry tries to rescue him but is stopped by Reverb and Deathstorm. Zoom arrives, kills Reverb and Deathstorm for harming the Flash, and then imprisons Barry alongside Jesse. Meanwhile, Jay reveals to Caitlin that he invented Velocity-6 on his Earth, and that it is the real reason why he lost his speed and is dying.

Right before the particle accelerator explosion, Joey Monteleone was thrown into a tar pit and left for dead. Sealed away, he is freed two years later with the ability to turn his body into tar. He sets out to get revenge on those who attempted to kill him. Meanwhile, Dr. Wells creates a device to syphon Barry's speed energy and attaches it to his suit. He and Barry also successfully find a way to close the breaches of Earth-2. When Barry goes after Joey, the device works, and permanently steals a portion of Barry's speed, slowing him down. Wells gives the energy to Zoom, who demands the rest. While going after Joey a second time, Iris is injured when Barry is too slow to save her. Watching Barry wrestle with the guilt of Iris' injury, Wells confesses. Wells pleads his case, asking to be returned to Earth-2 and have Barry seal the breaches so Zoom cannot re-enter. After stopping Joey with an invention of Wells', Barry realizes that Wells was only trying to save his daughter, which the rest of them would have done. The team informs Wells that he will return to Earth-2, but that Barry and Cisco will be going with him to save his daughter.

The team discovers Turtle is dead, and Jay suspects Dr. Wells is responsible. Meanwhile, Cisco asks Harrison for help in controlling his vibing abilities. Harrison determines they are connected to Cisco's fear response, and he triggers a vibe which alerts the team that Eobard Thawne is back. Wells surmises that this version of Eobard is from a point in the future before he went back in time to kill Barry's mother, and was thus protected from being erased with Eddie's sacrifice. Retrofitting goggles to induce Cisco's vibes, the team learns that Eobard is planning to use tachyons to return to his future. Barry arrives and destroys Eobard's tachyon machine. After a race around the city, Barry stops Eobard and imprisons him at the particle accelerator. However, his capture causes a rupture in the timeline that threatens to kill Cisco, so Barry is forced to send Eobard back to the future to save his friend. Meanwhile, Patty discovers Barry is the Flash, but when he refuses to acknowledge it, she chooses to leave the city. Caitlin tries to find a cure for Jay's illness.

As Dr. Wells struggles to try to find ways to increase Barry's speed, Cisco presents a new idea to slow Zoom down. Cisco tells the team about a metahuman, whom he has dubbed the "Turtle", who has the ability to stop the kinetic energy around him and thus slow everyone to a halt. After Barry fails to stop the Turtle at a diamond unveiling, the team sets a trap at a local art exhibit. Barry invites Patty, with the intention of telling her his secret, but the Turtle is aware of the trap and almost succeeds in killing Patty before escaping. Later, the Turtle kidnaps Patty in an effort to punish the Flash. The team tracks down the Turtle, and Barry is able to generate enough speed to move through the kinetic waves the Turtle creates to knock him unconscious and save Patty. Later, Patty tells Barry that she is leaving Central City, and Dr. Wells kills the Turtle while extracting a portion of his brain. Meanwhile, Joe struggles to develop a relationship with Wally, who has been street racing in an attempt to earn enough money to pay for his mother's medical bills.

Mark Mardon breaks James Jesse and Leonard Snart out of Iron Heights in an effort to team up to kill the Flash. Snart declines and warns Barry as repayment for him saving Snart's sister. When Patty learns Mardon is back in the city, she sets out to take revenge against Mardon for killing her father years earlier. Jesse and Mardon place bombs hidden in Christmas gifts throughout the city, threatening to set them off in family homes if Barry does not sacrifice himself. Wells, Cisco, and Jay find one of the bombs and alter its magnetic polarity; they send it into one of the dimensional breaches, which causes it to attract the remaining bombs, removing them from the city. With them gone, Barry subdues Mardon and Jesse. Patty arrives ready to kill Mardon, but Barry as the Flash talks her out of it. Meanwhile, Joe learns that his ex-wife was pregnant when she left and that he has an adult son named Wally, who later shows up at Joe's house. Elsewhere, Zoom visits Wells and agrees to release his daughter if Wells helps Barry become faster so he can steal Barry's speed.

Vandal Savage arrives in Central City looking to kill Priestess Shayera, who turns out to be Kendra, though she is not aware of it at first. Barry goes to Star City and enlists the help of Oliver and his team to protect Kendra until they can stop Savage. The team is visited by Malcolm Merlyn who informs them that Savage is an immortal who cannot be stopped. Later, Kendra is kidnapped by a winged man, but is rescued by Barry and Oliver who capture her captor. The man is Carter Hall, who tells them he was Prince Khufu in ancient Egypt and that he and Kendra are soulmates who have been connected for 4,000 years. The pair are destined to die, be reborn, and find each other in each lifetime. Carter also reveals that Vandal has killed them the last 206 lifetimes, each time growing stronger. Vandal locates the Staff of Horus, a weapon capable of killing Carter and Kendra, in Central City. After Kendra unlocks her abilities, the team decides to regroup in Central City to take down Vandal for good. Meanwhile, Caitlin and Harrison create a serum that will increase Barry's speed temporarily so that he can defeat Zoom.

Barry manages to recover following his fight with Zoom, but is unable to use his powers due to the psychological trauma of Zoom exposing his beating to the city. Iris reaches out to Henry Allen, who returns to the city to help Barry overcome his fears. Cisco has a date with Kendra Saunders, but leaves after seeing a winged man in one of his vibes. Grodd returns, using scientists to steal various chemicals in the hopes of creating more gorillas with his level of intelligence. He later kidnaps Caitlin to help him with his plan. The team dress Wells up as the Reverse Flash in order to trick Grodd into thinking that his "father" is still alive. The plan works long enough for Wells to rescue Caitlin before they both escape. After Barry is fully recovered, they lure Grodd to one of the dimensional breaches and send him to a jungle sanctuary for gorillas that have been experimented on in Earth-2. Later, Cisco meets Kendra again, this time vibing and seeing Kendra as the winged figure.

As the team works to find a way to stop Zoom, Doctor Light escapes from her containment cell after Barry was hoping that she would help them stop Zoom. Instead, her Earth-1 counterpart, Linda Park, agrees to help the team by impersonating Doctor Light. Dr. Wells creates a speed dampening serum and the team stages a fight at one of the breaches in order to trick Zoom through. The attempt fails as Zoom knew what they were attempting. Instead, he goes after Linda before fighting Barry. Zoom is much faster and easily bests Barry, showing his defeated, unconscious body to the local news and the police station, before ultimately returning to S.T.A.R. Labs. Zoom stabs Barry with his hand, but Cisco shoots him with the serum, which hurts Zoom but still leaves him with enough speed to escape. Later, Wells reveals that Zoom has his daughter Jesse and he came to Earth-1 to stop Zoom. Barry wakes from his injuries and discovers that he can no longer feel his legs.

The team meets the Earth-2 Harrison Wells, who is responsible for the creation of the metahumans and Zoom of his Earth. Despite his attitude, Wells plans to help Barry's team stop Zoom and his metahumans. At the same time, a thief from Earth-2 named Doctor Light arrives and starts robbing banks. Jay tells Barry that she can be reasoned with, and it works until Barry recognizes her as the Earth-2 version of Linda Park. Later, Light attempts to kill Linda and take over her life, but accidentally kills Linda's boss and is foiled by Barry's team in the process. Wells reveals Cisco's metahuman powers to the team, which Cisco uses to locate Doctor Light. Barry defeats her using a speed mirage technique that was suggested by Wells. After locking Light up, they plan to use her to lure Zoom and defeat him for good. Jay, who does not trust Wells, thinks it is too dangerous and leaves the team. Back on Earth-2, it is revealed that Zoom has Wells' daughter captive.

The team are able to stabilize Dr. Stein, but only for a short period of time while they can locate another viable partner for the Firestorm matrix. The team identify two potential candidates, a scientist named Henry Hewitt and a former high school football star named Jefferson Jackson. Hewitt is excited to merge with Stein, but the attempt fails and Hewitt leaves angrily, but also now unknowingly connected to the Firestorm matrix. Jefferson initially refuses, but when Hewitt goes on the attack with his new abilities Jefferson agrees to merge with Dr. Stein. After the successful merge, the new Firestorm joins Barry in helping to take down Hewitt, forcing Hewitt to get angrier until he burns himself out and loses his abilities. Meanwhile, Dr. Wells breaks into Mercury Labs and steals an unknown device. Later, Barry is attacked by a humanoid shark monster sent by Zoom to kill the Flash, but he is saved when Dr. Wells uses the device to incapacitate the creature.

The team locates one of the singularity breaches in the lab and Jay creates a device that stabilizes it and will allow him to return home, but he opts to stay to help Barry stop Zoom. Meanwhile, Lisa Snart shows up asking for Flash's help in rescuing her brother Leonard, who she believes was kidnapped. Barry tracks down Leonard, who reveals that he was not kidnapped but is working with his father, Lewis. Lisa swears that Leonard would never work with their father willingly, because their father was abusive toward her when she was a child. Eventually, the team determines that Lewis placed a bomb inside of Lisa and threatened to kill her if Leonard did not help him steal some diamonds. Barry infiltrates Lewis' crew with assistance from Leonard. Cisco successfully removes the bomb from Lisa, so Leonard uses his cold gun to kill his father in retaliation. Dr. Stein's condition continues to deteriorate, and Dr. Harrison Wells arrives through the singularity breach at the lab.

Jay explains to everyone that he is the Flash on his world, a parallel Earth, and that he was in a battle with a demonic speedster named Zoom when the singularity brought him to this Earth without his powers. Dr. Stein explains to the team how Jay's story could be possible using the multiverse theory, identifying their world as "Earth-1" and Jay's as "Earth-2". Zoom arrives and brings another metahuman from his Earth, named Sand Demon, to kill Barry. The two fight, but Sand Demon escapes. Cisco analyzes "sand" left behind and has a flash of the fight between him and Barry. After Sand Demon kidnaps Officer Patty Spivot, Jay teaches Barry how to hurl lightning from the energy he creates when he runs. Cisco uses his new power to tap into the "sand" particles and find Patty's location. Barry uses the lightning blast to turn Sand Demon's particles to glass, stopping him. Later, Officer Spivot joins Joe's metahuman task force. Cisco divulges his new ability to Dr. Stein, but asks him not to tell anyone. Dr. Stein and Cisco are able to locate 52 breaches with the other Earth. While showing the team, Dr. Stein collapses into unconsciousness.

Ronnie and Professor Stein turn into Firestorm and destroy the singularity, but at the cost of Ronnie's life. Six months later, Barry is now working on his own to avoid hurting any more of his friends and family; Cisco works in the police department alongside Joe and his metahuman task force, and Caitlin works at Mercury Labs. The city holds a ceremony honoring the Flash for his work in saving the city where they give him the key to the city. At the ceremony they are attacked by Al Rothstein whose strength and size manipulation prove too much for Barry to handle on his own. He is convinced by Joe and the others that he needs help in taking down certain metahumans and Barry defeats Al by allowing him to absorb too much radiation. In his dying breath, Al tells Barry that he was sent to kill him by someone named Zoom. Barry also receives a hard drive from Eobard Thawne containing his confession to killing Nora that finally proves Barry's father's innocence. They throw a party where Henry tells Barry that he won't stay in Central City, thinking that it could hold back Barry's duty as the Flash.
