Becoming the Flash
Barry was working in the CCPD lab one night after Julio Mendez left the lab, a violent storm happened and he was accidentally struck by lighting, putting him in a coma for few hours. Later in a hospital, Barry woke up completely safe, wondered about his life when he realized how close he was to die. Later at a dinner with Iris West, Barry and Iris talked about themselves but Barry wanted to return to the lab, which disappointed Iris. At CCPD, Barry received a call from the doctor, who revealed that tests showed some kind of cell damage and recommended Barry to make a check up at S.T.A.R. Labs but he declined knowing their bad reputation. Later Barry realized that he has speed but that makes him eat a lot, which frightens his dog Earl. Later, Barry checked his messages and realized he had missed a call from Iris who wondered where he was since he was supposed to help her setting up an exhibit at the gallery. Barry ran out to catch a bus but, going too fast, he ended up in the beach's water before passing out. After waking up, realizing that he had slept, he called Iris to apologize but failed to convince her that he had run "30 miles". Back at home he got a call from Tina McGee, and agreed to meet her the following morning at 50 Garrick Ave. Inside S.T.A.R. Labs, Tina made Barry run on a treadmill but, because he went too fast, it blew up. As Barry was hungry, they both went out to eat but Barry realized that he consumed a ton of food, revealing that his body is burning too many calories, which makes him wonder if he is aging prematurely. McGee asked him to keep his identity a secret since the last time S.T.A.R. Labs discovered something, it costed her husband's life. That night, Iris came to his place and Barry tried to clean up the mess but by doing so, his shoes melted and made stains all over his apartment.

Using this suit, he managed to reach the speed of sound. When Barry goes back to the lab, Julio revealed that the sample that he found belongs to Nicholas Pike, whom Barry recognizes as Jay's ex-partner. Realizing that his brother is actually on the same Highway, he figured out that it's a trap and ran to save him but when he arrived, Jay is already dead and the Dark Riders escaped. The next day, Barry and his father were at Jay's funerals and argued about how Barry is trying to go after after Pike himself but his father disagreed and tried to dissuade him to go after him. Later at S.T.A.R. Labs, he asked Tina to add a hood to the suit so that he can conceal his identity and bring Pike to justice. He then decided to add an emblem on the chest that Pike would fear. The following night, Barry attacked the gang and sabotaged their chemicals convoys but after taking out all the bikers, one of them managed to stab him in the leg and Barry had to avoid the police and meet some of his colleagues that brought him home, where Tina met him. At the lab, he found out that a sample from the crime scene originated from a unique place. Barry, as his alter ego, managed to get in their lair and found Jay's badge along with a plan that would break out the gang from prison. He later went to Cooper's office to explain that the Dark Riders will try to break out their friends in prison. Once a unit had been sent to stop the break out, Barry goes to his car but before he could wore the suit, he passed out due to his metabolism. Later at S.T.A.R. Labs, Barry woke up and got mad at Tina since he was supposed to be stopping Pike instead of be treated like if he was Tina's husband. At the prison, Barry toke out the inmate on the roof and put tear gas in all air conducts to force all inmate surrender. In the sewer, Barry confronted Pike but his metabolism, started to cause pain witch gave Pike the opportunity to beat him. When Pike tough that he was done with him, Barry got up and confronted him one last time and start to beat up Pike? Barry than created a tornado by running all around Pike to make him and shock him trough the prison power plant before tiding him up. After that Pike was arrested, Barry apologized to Tina for being mad at her and accept to figured out how to stop his metabolism for being a serious problem. The next morning, at the Allen house, instead of eating breakfast to celebrate Pike's arrest, Barry went outside with Shawn and told him stories about Jay in different situation of his life and Barry gave Shawn Jay's silver medal.

Barry told Paloma to call him if she learned anything new. Barry and Julio than went to the Santeria shop to interrogate the Santero but the only thing important that he could tell is that he knew that they must make a human sacrifice but he didn't know who. As Barry and Julio left, Paloma approached them and told them that the Santero was delusional. Sofia comes over and when Barry said that everything is okay, she complained that he was in no position to judge.

She must came forward or someone she loved will die in her place. Paloma showed Barry a newspaper article about her father and explains that he sent her there to hide with her aunt and uncle after Calderon killed her brothers. If Calderon found her then he would use her as leverage to stop her father from testifying. Barry than decided to take Paloma somewhere safe. Later at S.T.A.R. Labs, Tina ran a scan on Barry to find something out of the ordinary and Barry started to argue with Tina. Paloma came in, overheard them arguing, and said that she could handle herself but Barry insists that she has to stay, that he has work to do and left for the lab.

The next day, Barry and Tina goes to meet Joan at her veterinarian clinic and she assures them that she can handle the children. When he asks her what Sullivan was working on, Joan says that all she knows is that he was bringing home dead files from college. Terry and Cory turn the dogs loose, and Joan angrily orders the kids that they'll both walk the dog called Brutus. Later, at the lab, Julio finds Barry dozing. Barry wakes up and admits that the kids are keeping him up, and Julio gives him the information on Sullivan's murder. He confirms that the data Barry is looking for wasn't in the explosion since they were supposed to be in leather but since they didn't find any, Barry deduce that it was stolen. As Barry and Terry leave the station, Barry suggests that they go get some pizza but Terry tells him that they're better on their own. As they drive off, two person follow them in a van and drive them off the street. Barry is knocked out in the crash, and the two person grab Terry and leave. When Barry wakes up, he gets his costume out of the trunk and speeds after the van. He ties a cable to the back and the van jerks to a halt and then frees Terry and reminds him to never accept rides from strangers. Barry brings Terry back to the station and asks why those people grabbed him. Terry claims that he doesn't know anything, and Barry checks their records and confirms that they have drug records. Julio then arrives and warns Barry that the two guy he arrested are "freaking out" and Barry goes to see them. When he arrives, they've passed out, and Barry goes in to check them out. They wake up, go berserk, and attack Barry. Bellows and Murphy subdue them than they die from Blue Paradise overdose. Back at the apartment, Barry returns with Terry. As Cory goes to bed, she confirms that she can't stay there forever, and doesn't believe him when he says they'll find her somewhere that she can. Joan talks to Barry about Sullivan, who admits that he doesn't have anything on her husband's case yet. Once Terry gets Cory in bed, Barry tells him that the cops are looking for a skateboarding snatch-and-grab artist. Terry says that he's got Cory to take care of and nobody else will protect her, and Barry asks what he's lifted recently. When the boy says that he lifted a stuffed animal from a car a week ago, Barry asks to see what he took. Terry figures that Barry has been setting him up, figures that the Flash is the only one he can trust, and storms out. As the Flash, he stops Terry on the street and Terry shows his excitement when Barry says that he could test his speed with his skateboard and when they try it, he finds it cool. When they stoop, Barry lecture him about the fact that he must trust someone that can help him and that will protect him and his sister before running away. Later, Terry gives the bag that he stool with the puppet from last week and Barry finds a magazine with Beaugarde Lesko face on it and some Blue Paradise. Later Tina analyzes it and goes back to the apartment with Barry where she explain that its a hallucinogenic drug. Barry tells Tina that the only one who were capable of this was Lesko according to Sullivan's notes and he supposedly died 20 years ago. After leaving the kids with Joan, Barry goes to the lab and shows Julio the newspaper article on Lesko's death in a plane crash. His body was never recovered, Barry figures that Lesko faked his death and went underground and calls a police car to watch his home to make sure that nobody will get those kids. Later, after that Terry ran away, Barry manage to convince Cory what terry is up to and she shows him a disk giving clue that he went out to sell one of the disk. Barry as the Flash finds Duvivier and after disassembling his car he grabs him asking Lesko's whereabouts and once he cracks, he gives a ways his location and Barry ties him up and delivers him to the station. Barry than goes to Lesko's lair and punches Lesko. He then asks Terry to get off and while he was about to punch Lesko again, Lesko makes him breath some Blue Paradise. Out of control, Barry vibrates so fast that he phase through the wall. Outside Terry finds him and Barry realize that he vibrated so fast that he has burned the drug out of his system. Barry than runs into the lair again put the speaker to max volume before playing electric guitar causing everyone around to be hurt by the sound and the equipment to be destroyed before they can gather them. He then break the guitar finishing to drive unconscious the remaining members of the gang. The next day, Terry and Cory prepare to head to New York City by bus. Barry wishes them well and hugs Cory. Joan pulls up and suggests that they live with her. Terry doesn't want to hear it assuming that Barry set him up again, but Cory insists on staying. Barry tries to convince Terry if he's tough enough to do the right thing, and Terry agrees to do it but under one condition, that the next person that asks him to shampoo a cat dies.
The next week, Barry investigate on a crime scene with Julio where a Judge and his wife were killed. Since they found evidence about explosives uses, they recommend Garfield to search to old case and find anyone who has been released that has a history with explosives. When he left, Barry notice an engagement ring felt of Garfield jacket and give it back and they gave it back to him and says that it's a "big step". The next morning, Barry is analyzing the explosives but since the equipment is broken, he shake it with his hand to get the result faster and Julio who entered the room caught a glimpse of him using his speed but assume that it was his eyes that blurred. Julio then reveals that it was made of titanium and Barry decided to pay a visit to Jack Callahan a specialist that they booked years ago. As the Flash, he interrogates Callahan about the titanium used to create a bomb. When Callahan calls back up, Barry handcuffs them and destroys all of his gunrunning operation and when he interrogates him again, he stills refuses to talk and Barry runs away. That night at a restaurant with Tina, Barry explain how Callahan was ready to die with his secret and Barry deduce that the man behind the murder must be powerful enough to be feared but Tina reminds him he promised that he would not talk about police related stuff and then Tina reveals that she receive an offer from a research institute in California and Barry realize that he won't be able to see Tina frequently. Then Frank Dejoy a lawyer and Barry's friend greet him only to be killed by two arrows seconds later. Barry fond a pieces of medallion that resemble the one found on the previous murder. Barry saw the assassin running away and uses his speed to catch him but the assassin shot him with a laser gun that knocked him unconscious. The next day, Garfield shouted at Barry for leaving a crime scene and disappearing and Barry show the two pieces of the medallion to justify his investigation and prove that the murders are related. Garfield tells him that that a god job but he warns him that it doesn't excuse what he has done and the next time it happens, he will get suspended. Since Barry's back is hurt, Julio recommends him to go see a doctor but Barry asks him to cover him at work for a couple of hours. Barry ask Julio before living to search anything about cases the judge and the lawyer where implicated in and Julio asks Barry why did he tell the Lieutenant that he was in the lab last night since Julio was there and didn't saw him. At S.T.A.R. Labs, Tina is mad at Barry for forgetting to call her to say if he was alright after the murder and Barry asks her again if she can fix his back but Tina is still mad at Barry from easily accepting the fact that she could leave to California and Barry leaves. At the lab, Barry search emblems about who could the medallion represent and asks Julio to go get some coffee and speeds up the process. But Julio saw him again and Barry tries to tell him that he is a little bit sick. Barry than figures out that the medallion represent the Warriors of Freedom. And figures out that this used to be the emblem of Jefferson Zacharias's gang and that the murderer is after every one that lead to Jefferson arrest including lieutenant Garfield. Barry asks Julio to send back up to the lieutenant and Barry speeds away. When Barry arrived (as the Flash), the shooter has already shoot Mavis Garfield's fiancée but he manage to deflect bullets aiming for Garfield. But the time Barry arrives on the roof, the sniper got away and he finds only the sniper. Later, as Barry Allen, he took the testimony of some witnesses before Garfield asks him what do they have on the shooter. Barry explains that the shooter has left the sniper but he suspect Callahan for being the one that sold the weapon. Garfield orders Barry to leave Callahan and after forcing to much on why Garfield is protecting Callahan, Garfield explains that Callahan was a mole inside the Warriors of Freedom and was the main responsible of taking them down but in exchanges, every aces to his record is restricted. He then tells Julio to finish the analyze of the crime scene while he goes to Helltown to ask question about the gun pro-curation. When Barry arrives, he finds Callahan with multiple gun wound and he manage in his last breath to say "Angel". Barry than found the last pieces of the gang medallion on Callahan's neck. Barry than call Julio to identify a member of the gang tha goes by "Angel" and Julio who read the file explain that Jefferson has a daughter called Angel Zacharias. When Barry arrives at the station, Julio gave him a file on Zacharias's daughter and reveals her military past and the fact that her parents where divorced when she was 13 and lived most of her life with her mother and that the day after his dad was executed, she ran away from home to join the military until she was discharged last month. Julio than reveals that Garfield has already taken the first file on her 15 minutes ago and Barry realized that he is not going to arrest her but to kill her. When Barry arrives, Garfield is on a pressure plate trapped with a detonator and Barry manage to save him but got knocked out in the explosion. Later, Barry would wake up and speed to the hopistal just in time to save Mavis from being poisoned. After manipalting the grappe hook of Angel to avoid Garfield killing her, Barry meet and avoid all of shuriken on the roof but when Garfield enter the roof, Barry was distracted and got hit in the leg. When Garfield was about to kill her, Barry manage to convince him that her action was led by hatred like he is led by hatred. Realizing that he was right, Garfield put the gun down and arrests her. Days later, Barry joined Garfield wedding with Mavis and Julio reveals that he figured out that he was the Flash but Barry tricks him into believing that the Flash is another person by showing up in different place at the same time without Julio realizing that he was gone. Tina reveals that she has turned donw the offer and ask Barry who is hungry and looking at a pizza truck, to keep a slice for her.
The following week, Barry and Julio went to S.T.A.R. Labs to give back Tina's computer and Barry commentated the fact that their equipment are better that those of the police and Julio asks what does Barry do in S.T.A.R. Labs those days and since Barry couldn't find a good excuse, he assumes that he and Tina are a thing. Tina than appears and learns that Barry, Julio and Sabrina participate to a telephone game service on TV and Tina agrees to come even if Barry doesn't like it. Later, at his apartment, Tina rang the bell and Barry uses his speed to get dressed before answering the door. Later, while answering a phone, Barry complains that there is aw woman that called him three time already to match him with her daughter and Joe Kline than asks Barry to move because Joe wants to seat in the middle. He asks Sabrina is she wants a coffee and she answers that he wants Julio to take one too since he is distracted by another woman. They go meet Garfield who successfully finish a magic trick. He than asks Julio if he can be his magic partner Monday before introducing Dr Desmond Powell But the stage is interrupted by armed criminals that broadcast a man. As the Flash, Barry manage to save some civilian from being crushed but the two thugs gets away with it. Later, after the incident, Barry tells Tina that it was a bad idea to go there. The next morning, Garfield took Barry's breakfast and Powell enter the room and tells them that the man that was on the broadcast, was the Ghost. Barry than learns about the Ghost background and the existence of a vigilante called "Nightshade" that has defeated him. At home Barry listen to the new but Kline's broadcast is interrupted by the Ghost that asks the Flash to meet him at S.T.A.R. Labs. Barry than suit up and runs into S.T.A.R. Labs where he disarms the two thugs from earlier but he is trapped in a laser cage. Suddenly, Nightshade shows up and shot Skip with a tranquilizer but is injured by the latter. Barry manage to break the device that traps him and discover that Nightshade is Dr Powell. Barry than goes to Powell's car and use the first aid kit to save his life. After bringing him to his car, Desmond tells him that "it's nice to meet the man who picked up the torch" before Barry leaves. He comes back seconds later as Barry and help Desmond to escape the police. At Nightshade's lair, Barry is surprised about how much Powell has done for the city but that no one remembers him. Powell than state who would remember the Flash in 35 years before they leave. Later, at the lab, they realize that the Ghost is jamming all connected computers in the city and Desmond states that he will fight him alone in the frustration of Barry. As the Flash, Barry followed Desmond interrogating Belle Crocker and ask him how he can help. Desmond give him Intel about the Ghost's lair and Barry speed to the location. At the lair, Barry and Desmond talk about how Desmond defeated the Ghost years ago. The device that helped to fry his system is broken now and Barry take it to S.T.A.R. Labs so that he and Tina could repair it. At S.T.A.R. Labs, Barry uses a treadmill to powers the room with electricity and repair the device. later, dressed as Nightshade, he would trick the Ghost to ask his thugs to get out and attacks him. During the fight, the Ghost manage to bring Barry into his world and tortures him. Luckily for Barry Desmond used the device to fry the Ghost's machine and save Barry from his world. Barry than takes off all the wire to neutralize the Ghost and cuff him to a chair. Later, at Nightshade's lair, Barry tries to reveal his identity but Desmond doesn't want to know. He then tells Barry that he is retired and that Barry should also start a collection and on this, Desmond give him his mask.
The next week, In S.T.A.R. Labs, Barry is talking to Tina about going horse racing with him and Julio. Tina tells them to go on without her because she's working on a report for her chief administrator employer, Ruth Werneke. As Barry says that Ruth is tight, Ruth comes in and asks for the report before dawn. Once she leaves, Tina jokingly admits that she wants to strangle Ruth sometimes, and Barry leaves. At the lab, Barry tells Julio that Tina isn't coming much to Julio frustration as it is in his family tradition to have a woman picking up the winning horse. Barry than calls Tina but he gets a recorded message in case of emergency lock-down. As the flash, Barry arrives in the front door and find it sealed and when he tries to get in, he receive a shock that pushes him back. As Murphy and Bellows arrive. As Barry Allen, he tells them to stay away from the door before going in Tina's van and accesses the computer. Barry rigs up a video hookup through the satellite computer and Tina tells him what happened. She says that Barry can't break the seal because it will trigger an irradiation sequence that will kill both of them. Tina plays back the video and they watch Bernhardt's death and the release of the chemical into the air system. Tina figures that the thief used an electromagnetic stealth device, and determines that Project Pandora is a project for a government weapons research center to develop nerve toxins. Ruth is the project coordinator and she insists that the toxins would have never get used, but she points out that the intruder used it. Dr. Emil Velinski is the project director, and Ruth gives Barry an approximate address. But when Barry arrive where he could find Velinski, he is dead with only the blind Reggie as a witness. Reggie describe the murderer height and breathing and Barry leaves. When Barry returns to the van, Tina tells him that the thief took one of the two vials of the toxin and the one vial of the antidote. Barry explains that Velinski is dead and Tina warns him that the remaining vial could kill everyone in Central City. She says that according to the computer, they have less than four hours to live. As Barry, he is introduced by Garfield to agents Quinn and Edwards who supervise the setting up of the security perimeter around STAR Labs. Barry says that Tina and Ruth are exposed and Quinn says that they've been monitoring Barry's conversations and says that there is no such thing as an electromagnetic stealth device and they'll have the vial back in 24 hours. Barry points out that the sterilization will kill the women if the agents try to get in but Quinn makes it clear that he don't want Barry to interfere. He says that the government is under federal jurisdiction and tells Barry to leave. Garfield reluctantly agrees with Quinn saying that the federal government has contacted the mayor. Later, at the lab, Julio suggest to Barry to jam Quinn's signal and contact Tina via the police network. Once the signal is jammed. Barry comes in and Tina tells him that she's trying to analyze the toxin. She gave him the name and address of Velinski's assistant, Taylor Cartwright. Barry manage to bring Cartwright in and but he warns him that it could take days to reconstruct the antitoxin. Barry agrees to help, and Tina asks to talk to Barry alone. Tina tells Barry to find the other vial of toxin and forget about them and she says that if anything happens to her then he should take care of him. When Quinn and his people barge in and shut down the jammer, they take Cartwright with them and Barry grabs Quinn. This caused Quinn to order Edwards to arrest Barry for interfering in a government investigation. Barry tells Quinn that the killer will bring the vials to Quinn when he tries to kill Cartwright like he killed Velinski. Barry vibrates the handcuffs off and as the Flash, he finds the dying assistant in a car. The invisible man than attack Barry but Barry manage to throw him into the windshield, and the cloaking device shorts out revealing to be Brian Gideon before he disappears. At the police lab, Barry uses the computer to check Gideon's connection to STAR Labs. Gideon is a biochemist and physicist who worked briefly for S.T.A.R. Labs six months ago. Before that he worked for the government. He lost his security clearance and was fired, and Barry decides to go talk to him as the Flash. A proximity alarm goes off as Barry enters the lab. Gideon uses the device and fades away, and Barry tells him that there are two innocent women trapped in S.T.A.R. Labs. Gideon says that 2,000 people died in Costa Luca and no one remembers them except him. Quinn was in charge of the incident and claimed that it was a factory leak. When Gideon went to S.T.A.R. Labs to start over, he found out they were working for Quinn. He insists that there are no innocents and they are all responsible and convulses briefly. Gideon takes some pills and explains that he has a brain tumor from his time in Costa Luca. Barry asks for the antidote to save his friend, and Gideon says that they'll all be dead. He states that if people die in Central City, then maybe it will bring Quinn's efforts to the world. Barry tells Gideon that he'll help him get to the press than Quinn calls on Gideon to surrender telling him that he just wants to talk and Gideon figures that the Flash set him up. He turns invisible, knocks him back and leaps out the window. Barry manage to grab Gideon's voice log and goes after him as the government agents break in. Barry returns to the police lab and Tina sends a fax about the heat signature. He faxes back saying that he'll pursue the idea tells Tina not to give up hope. Barry then calls Search & Rescue to get their heat-signature equipment. Julio plays back the voice log and Gideon mentions poisoning the well. The two men realize that Gideon is going to put the toxin in the reservoir. Barry arrives to the reservoir with the heat-detection device and infrared contact lenses and searches for Gideon. Gideon injects him with the toxin and Barry collapses. As he goes to the water supply, Barry accelerates his metabolism to burn the toxin out of his body. The lights flicker, and Barry realizes that the stealth device causes a power surge. He wraps wiring around a pipe to create an electromagnet and burns out Gideon's belt as he prepares to put the toxin into the water. Dying, Gideon says that someone has to do something and they're all responsible. He warns that the vial is destroyed, and after Gideon dies Barry takes the stealth belt. Barry speeds in and gets Tina and Ruth out just in time. He figured out that the blood is the antidote, and inject them with it. Once they are recovered, Barry and Garfield arrive and tell Quinn that they've reported Quinn's activities to the mayor. Edwards confirms that she has been ordered to detain Quinn pending full investigation of his actions and Ruth says that she'll call a press conference to expose his activities. After the others leave, Barry suggests to Tina that they use her computer to place bets on horse racing. She says that the only horse that she'd bet on is the Flash. Barry goes over to Quinn and offers him the dismantled stealth belt, and says that Flash delivered it to him.
The next week, Barry is watching Joe Kline's news report which tells that Wayne Cotrell, a saxophonist is about to be executed tonight for the murder of Linda Lake. He notices Julio disagreement for his execution with during an argument with Garfield since Julio strongly believe that he is innocent. A Musician called Dave Buell calls the lab looking for Julio but as Julio has just stormed out of the lab after an argument with Garfield he gives Barry a message. He has stolen a tape that will prove Wayne's innocence and wants Julio to meet him at the Take Five club in 15 minutes. Before he has a chance to hang up Dave is attacked and murdered and Barry speed to his location. Seconds later, Barry as the Flash arrives but only finds his hat and the tape is crushed by a truck. Barry tells Julio to meet him at Take Five after warning him about Dave's message in five minute. When Barry entered the club, he saw Elliott Cotrell, Wayne Cotrell's brother giving an interview to Joe Kline talking about the innocence of his brother and Barry finds Dave's trumpet case and notices that Julio almost started a fight with the security guard Whisper. After that Elliott stopped the fight, he recognises Barry as he is a regular patron of the club. Barry asks Elliott if the rumour of unreleased tracks by Linda are true. Elliott says if they exist and if he finds them he will release them for all her fans to hear. Barry remarked that he could make a fortune if it's true and asks where Dave is and Elliott claimed Dave was in Chicago. Barry finds him suspicious as he knows that's not the case. Once out of the club, Barry show Julio the broken tape and believes that Tina could fix it. Barry picks Tina up from a performance of Swan Lake and brings her to S.T.A.R Labs. He explains the situation to her and she thinks she can digitize the tape but it may not be finished in time. Barry as the Flash than runs inside Contrell's cell and asks him his side of the story. He explains that a woman named Suzy Storm is his only alibi and that she mysteriously diseppear with no trace and that she wore some saxophone earring. And went Barry tells him that Linda was leaving him to LA, Wayne said that Linda made her first record with Elliott his producer but she didn't want to do a second one with him as he was too controlling. She was going to LA to work with a big time producer who would let her call the shots. Barry than promises Wayne that he will do whatever he can to prove his innocence before leaving. Once Tina has digitized more of the tape. Barry hears a recent tune by Dave Buell with Linda's voice singing over it. Tina asks how that can be the case as Linda was killed a year ago. Julio arrives and tells them what happened to Dave. They tell Julio about the tape and he thinks it's a fake. Tina than compares the voice print from the tape with Linda's CD and it's a perfect match. Once Tina plays more of the tape, they hear Elliott voice saying “I’d like to help you remember”. Julio and Barry decieded to go through the evidence bag and they find a custom made saxophone earring that was found in the car wreck where they also found “Linda’s” body. The only reason they thought it was Linda was due to her dental records and Julio deduces that the dental records must have been switched with Suzy storm's. Barry and Julio go off to confront Elliott. They ask Tina to call the governor so he can stop the execution. At the Take Five, Barry notice that Linda's window emit light which makes him wonder who could be there. While Julio enters the club, Barry as the Flash enters the room and sees Elliott at a mixing desk and a very much alive Linda singing a new song. Barry notice that Elliott is drugging her Linda which make her lost her memory and keeps her locked in his apartment. He tells her until her memory returns, the "medecine" it's for her own good. Once her and whisper are gone, Barry enter the room and asks Linda to come with her bu Whisper attacks him and throw him off the window. Minutes later, Barry wakes up and stops Whisper from beating Julio before taking Linda to the prison. Once there, Barry releases Contrell from being fried and the police almost shot him but once the notice that Linda is alive, Elliot takes a gun and threaten everyone only for being stoped by Barry a second later. Days later, Barry and Julio are in Take Five watching the reunited couple playing together. Once they finished, they go seat at their table and Linda states that Julio and Barry will always have a seat there. Wayne than states that he is about to change everything that Elliot has done there but not the clock that the Flash trowed Whisper into as a good memory. He then show them that he has changed the Buffalo wings into Flash wings which makes Barry laught.
At some point before December 2018, Barry Allen became John's friend. John wears a ring and is implicated by Barry having some kind of ability or special power.
The Monitor's test
Devastation of Earth-90
"Why are you doing this?" "You did this to yourself. And now, all of you will perish.
|~ Mar Novu and Barry Allen|
When Mar Novu arrived on his earth to test it, the Flash along with the other heroes confronted the Monitor but were no match for him and in the resulting immense battle, the Flash was the only survivor and dragged himself towards a giant book that glowed with purple energy but Novu got there first. When Barry asked why he was doing this, Novu said that they had done this to themselves, and that they would now perish. He then opened the book, which began to glow, while The Flash ran off to escape to another universe.
|“||Enough! You will not do to this Earth what you did to mine.||„|
|~ Barry Allen to the Monitor|
Barry attempted to breach to the Monitor's next target, Earth-1, creating red skies and lightning which followed Earth-1's Barry Allen and Green Arrow, whose lives had been swapped by the Book of Destiny. Eventually, when Team Arrow and Team Flash create a quantum flux anchor was Barry able to open a portal through which he warned them about the Book of Destiny and urged them to acquire the book if they have any hope of fixing their Elseworld, before closing once more.
Sometime later, Barry finally succeeded and fully breached through at A.R.G.U.S. At first he was mistaken for his doppelgangers, Jay Garrick and Henry Allen, before formally introducing himself. He then mistook John Diggle with his Earth-90 doppelgänger, remarking that doesn't possess a ring. He then explained of the threat of Mar Novu, who had since taken on the moniker of the Monitor and was unleashing the Book of Destiny across the multiverse to test different Earths in preparation for an impending crisis. Just then, the Monitor appeared on TV, so Barry joined the heroes and they set out to try to attack him. During the confrontation, The Flash declared he would not let the massacre of Earth-90 repeat and attempted to attack first but the Monitor made him vanish before he could take a step.

|~ Barry Allen|
The Anti-Monitor found him and put him in his lair in the Central City sewers where he was forced to run on a treadmill to power up the Antimatter Cannon. During the Crisis of 2019, Barry was found by his Earth-1 counterpart alongside Cisco Ramon, Caitlin Snow and Pariah.
Later on, Barry took some of Earth-1's speed and took his place by running in the opposite direction, sacrificing his life to disable the antimatter cannon.
|“||Tina, I watched myself die. It really brought home to me what you've always tried to make me understand. That I am only a man. And like all of us, I'm on a journey of a birth, a life, and a passing.||„|
|~ Barry Allen to Tina McGee on his mortality|
Barry's death saved the life of his Earth-1 counterpart, erasing the long-existing timeline in which he died during the Crisis.
His resemblance to Earth-1 Barry's father, Henry Allen, had caused him to commiserate with Jefferson Pierce on their respective fathers and the legacy it left them with.
