"My name is Barry Allen, and I am the fastest man alive." "To the outside world, I'm an ordinary forensic scientist, but secretly, with the help of my friends at S.T.A.R. Labs," "I fight crime and find other meta-humans like me." "I hunted down the man who killed my mother, but in doing so, I opened up our world to new threats, and I am the only one fast enough to stop them." "I am The Flash." "Previously on "The Flash"..." "Why are you here?" "Because I want to go faster, and you're the only one who can teach me." "Everything you need is on this drive." "It means a lot, you looking after Barry." "Barry's not the only person here I wanna keep safe." "We found Barry's double, so where the hell am I?" "Reverb." "You don't even know how powerful you are." "My name was Hunter Zolomon." "I thought that if I could find my doppelganger on this Earth," "I could replace my damaged cells with some of his healthy ones." "I've been vibing Zoom, and every time it's happened," "I've been near that thing." "I saw Jay." "He's Zoom." "Sometimes terrible things happen to us when we're children." "Things that can define who we become, whether we want them to or not." "Run, Barry, run!" "Some of us become stronger." "The people who took me and helped me heal and move past everything that happened." "They're responsible for who I've become today." "But I know that I'm one of the lucky ones." "Come on, Barry." "Not everyone gets that kind of support." "Without it, I don't know where I would have ended up or what I could've become." "[glass shatters, thudding]" " James..." " Who do you think you are?" "Do you know what I went through over there?" "Do you know the sacrifices I made for you?" "I come back after years of fighting for this country and this is my welcome home?" "[grunts]" "You think you can walk out on me?" "I'm your husband!" "You're not my husband." "I don't know what you are right now." "I am a hero, Ashley." "No." "You're a monster." "Run, Hunter, run." "Stay, boy!" "[both grunting] [panting]" "It's okay." "Please." "Please don't do this." " Shut up!" " No, please." "No. [sobbing]" "You're gonna want to see this, son." "No, James!" "[sobbing] Please." "No." "No, James." " [gun cocks]" " No!" "[gunshot] [somber music]" " Name?" " Hunter Zolomon." "Father killed the mother." "Kid saw the whole thing." "Next of kin?" "No relatives wanted him." "He is all alone." "Follow me." "And don't dawdle." "Okay, you guys." "I'm here." " You got my location?" " You're good?" "You don't need to, like, stretch or something?" "No, no, no, I'm good, I'm good." "Let's take this tachyon enhancer out for a test drive." "All right." "Hoo, yeah." "I feel that." "That is the tachyon device powering up the Speed Force in your cells like a quick charge battery." " How do you feel?" " Different." "Let's see how long it takes you to get back here." "On my count." "Three, two, one." "Go!" "Dang, this thing got you cruising." " How fast does he normally go?" " Not this fast." "Not even close." "Are his vitals okay?" "Yeah, they're perfect." "Cool." "It's like having a pit-stop attached to your chest." "Guys, I can go faster." "Do it." "I'm back." "What... how long was I gone?" "Let's put it this way, you just annihilated your old record." "Yeah, you went four times faster than you have ever been." "Four times?" " That's as..." " Fast as Zoom." "Well, faster actually." "Hey, uh, do we think that, um, we can get this thing smaller?" "It kind of sucks." "If it sucks, then, yeah." "All right, so now all we have to do is figure out how to get back to Zoom." "Yes, uh, just a minor issue." "We closed all the breaches and have no idea how to reopen them." "We don't..." "Um, Wells?" "Yeah, I have an idea, Allen." "Let's keep the breaches closed forever." "Forget about the breaches." "Forget about Zoom." "Wait, I'm sorry," "I thought that you were on board with this." "No." "No." "I said I would help you get faster." "I did not say I would help you give the man who kidnapped my daughter and tortured her a chance to do it again." "Hey, we are not gonna let that happen." "Oh, you're not gonna let that happen." "Gosh, I wish I'd known that the first time." "You don't understand Zoom is different than us." "Zoom is not tied to anything." "Zoom does not care for anyone." "I do." "My daughter's out here on this Earth somewhere." "I have to find her." "We all have people that we care about." "Zoom will use that against us." "Believe me." "Maybe we should just leave it be." "No, no." "Look, no." "Look, we're..." "We're not turning our backs on another Earth." "We're not gonna let Zoom get away with everything that he's done." "Right now, there is no way to another Earth, Allen." "Let's keep it that way." "We're getting back to Earth-2." "With or without his help." "Let's go to work." "Hey, where are you going?" "We could use your help." "Uh, yeah, I would." "It's just I have a date with Scott." " That's the editor?" " Yeah, yeah." "That's good." "No, I'm glad that you're finding a way to move on without anything holding you back." "You deserve that." "Yeah, and well, I would have been able to do it without your support." "It means a lot to me, so..." " Of course." " Thanks." "Yes, for sure." "Well hey, I mean, if you don't get this breach problem fixed by tonight, pencil me in for tomorrow?" "I can do that." "Okay." "Man, I love it when you train" " in Keystone City." " Mm-hmm." "Hey, you sticking around after dinner?" "Me and Wally are gonna watch Formula 1." "Mm." "No, I can't." "I got to get back to the lab." "I'm still trying to find a way back to Earth-2." "Can't you just stick Wells on it?" "No, he refused." "Doesn't want me or anybody opening the breaches again." "Well, I can't believe I'm saying this about a man I shot at..." "And punched in the face, but I think you should listen to him." "Why?" "Barry, it worries the hell out of me the thought that you want to go back to Earth-2." "I'm faster now." "I'm faster than I've ever been." "I'm faster than Zoom." "I can take him down." "All I'm saying is, you already escaped the hornet's nest once." "Why go back and kick it again?" "[door opens]" " Hey." " Wally!" "We got some pizza here all the way from Keystone City." "Hope it's cool I brought my laundry over." "Of course." "Barry used to do his laundry here all the time when he was in college." "That's cause those machines in the dorm always eat your quarters, right?" "Actually, I'm not, uh, living on campus anymore." "What?" "Since when?" "Since room and board became way more expensive than I thought." "Man, I can help you out with that." "I mean, I figured your money must be tight after paying all your mother's medical bills." "How much more is it?" "No, it's, uh, it's cool." "Come on, Wally, let me help you out." "Plus I got that mini-fridge in the garage." "You can use that, too, if you want." "Joe, I'm good." "Really." "All right." "Uh, let me just put these in real quick." "Man, I can't figure that kid out sometimes." "I wonder if his doppelganger's that complicated." "Hey." "Wow." "Um, any ideas?" "Well, the best plan we've come up with so far is to set off a nuclear warhead next to the city's electrical grid, so..." "We're not gonna do that." "Um..." "I think I thought of something though." "[dramatic music]" "Tell me everything that you know about Cisco's doppelganger." "Reverb." "What were Reverb's powers on your Earth?" "He could tap into the multi-dimensional energies between Earths." "He could see through dimensions." "Find breachers, like Ramon." "I mean, we... we saw Reverb do more than that though, right?" "I mean, we saw him shoot vibrational bursts out of his hands." "Really painful ones." "What do you mean?" "I..." "I mean, Reverb had the ability to somehow manipulate that multi-dimensional energy." " What's your point, Allen?" " My point is... if his powers are linked to the energy that ties together the multi-verse... if he can manipulate it..." "Then he can open a breach to any Earth he wants." "Exactly." "And if Reverb could do it..." "I could do it too." "Cisco, I think the way back to Earth-2 is you." "I got nothing." "Try again, okay?" "Barry, what if he can't do it because he thinks he can't do it?" "He can do it though." "You can do it." "[suspenseful music]" "[scoffs]" "You... it's gonna work, okay." "Maybe we're just not in the right place." "Or maybe I'm just not the right man for the job." "Right?" "Let's go." "Cisco." "I'm sorry, Barry." "[sighs] It's gonna work." "[knocking]" "Detective, um," "I need to ask you..." "Oh, you've got company." "Um..." "No, it's, uh, cool." "I should be studying anyway." "Do you know you kind of look like that guy..." " I'm not him." " Okay." "Later, Joe." "Ah." "Thank you." "Look, um," "I apologize for dropping by unannounced." "I just... have you had any luck locating my daughter?" "Not yet, but I circulated her picture through every department in the region." "And I reached out to some friends in Keystone." "She's smart." "She's gonna know how to stay hidden." "She's..." "We'll find her." "Right." "There's another thing also, Detective." "A favor." "I would ask you to talk Barry out of reopening the breaches to my Earth." "[laughing]" "Ah, I can't do that." "No." "You can't find a way to change his mind for both our children's sakes?" "Look," "I think it's just as dumb as you do." "but I learned a long time ago that I can't talk Barry out of anything once he sets his mind to it." "Zoom is terrorizing this other world... your world." "He can't let it go." "But look, why don't you do me a favor?" "Go with Barry." "Help him." "Help him?" "Why would I do that?" "'Cause he's got a much better chance of defeating Zoom if you're involved." "[increasing beep]" "This area has the highest levels of residual trans-dimensional energy." "Should be able to open the breach that used to be here." "[steady beep]" "It's right here." "This is it." "For real?" "In this Patch Adams nightmare right here?" " Yeah." " Love it." "All right." "Look, dude, if this doesn't work," "I'll stop asking you to do this, all right?" "Okay." "[exhales deeply] [suspenseful music]" "[exhales sharply]" "What?" "I can't do it." "That's right." "You can't." "What are you doing here?" "You said..." "I know what I said." "But you're not gonna stop, are you?" "No." "Okay, Barry Allen, then I'm gonna do what I can to make sure you don't get killed." "I recalibrated these to the electromagnetic frequency of this Earth." "It should help you access enough of the trans-dimensional energy to manipulate it." "Just like Reverb." "All I'm missing is the guyliner and the transformation's complete." "Take 'em out for a spin." "[suspenseful music]" "♪ ♪ [sighs]" "♪ ♪" "[futuristic humming]" "It's working." "♪ ♪" "[energy crackling]" "Keep coming, Cisco." "Keep coming." "It's working." "Hey, what... what happened?" "You were doing it." "No, no, no, no." "I-I can't do this." " What?" " Don't." "Please, don't ask me to do this." "Please." "Hey." "What do we got?" "It's your tachyon absorption enhancer upgrade." "Retrofitted from when it was used to steal your speed, to now give you more of it." "Almost done." "That's amazing." "Thank you." "You're welcome." "Is Cisco back yet?" "Have we seen him?" " I haven't seen him." " Check his workshop." "Yeah, all right." " Hey." " Hey." "We just came by to see if you guys needed some help." " Oh." " Uh, sure." " Yeah." " We can always use an extra set of hands." "Do you want to help me in the med bay?" "Yeah." " So this..." " Huh?" " This whole Wally thing..." " Uh-huh." "He won't let me help him." "[chuckles] It's probably 'cause you're not offering the right kind of help." "Wally doesn't want your help paying for a place to live." "He wants you to offer him a place to live." " Why didn't he just say that?" " I don't know." "So he does want to live in our house?" "Yeah, man." "Look, Wally's never lived with his father before." "And trust me, that is a big deal." "Huh." "And you're good with it?" "Mm-hmm." "I mean, you know, it's been you and me for so long, and I love that, but having Wally around would be cool too." "Just we won't get to have as much pizza from Keystone." "Yeah, it kind of sucks." "I'm sorry." "Have to get used to that. [laughing]" "They really have a special bond, don't they?" "Yeah, they sure do." "Are you okay?" "I don't know what I am." "Last night, I was supposed to go on a date." "My first real date since Eddie died, but at the last second, I just..." "I couldn't do it." "Is it because of Eddie or because of Barry?" "I've noticed the way you've been looking at him recently." "Is it that obvious?" "Only to a woman who's been through the same thing." "Everything seems to be telling me that Barry and I are meant to be together." "I mean, on Earth-2 we're married." "In the future, we're supposedly married." "And now that I'm finally ready to move on," "I just wonder if that should be with Barry." "Everything seems to be pointing in that direction." "Do you believe in destiny, Caitlin?" "Maybe for you." "Hello?" " Joe?" " Wally, I'm up here." "Hey." "What are you doing?" "It's not done yet." "I mean, you can decorate it how you like." " Make it your own." " Whoa, wait, Joe." "What is this?" "Wally, forgive me." "When Barry and Iris went to college, they couldn't get away fast enough." "They wanted nothing to do with their old man." "It didn't even occur to me that you might feel differently." "It's embarrassing, but it took Barry to help me see that." "So, if you still haven't found a place to live, live here." "I mean, it's yours if you want to." "You're serious?" "I'm not gonna do your laundry." "And I'm not washing dishes after you." "And this bed is going to be made every morning before you leave." "And there will be no beer in that fridge, but yeah, it's yours." "When can I move in?" "Whenever you want." "All right." "Thanks, Dad." "[chuckles]" " [chuckles] - [grunts]" "Hey, man." "[sighs]" "Look, um..." "I know what it's like..." "Zoom, getting in your head, how scary that can be." "It's not Zoom." "It's me." "What do you mean it's you?" "It's like right now I'm Anakin Skywalker." "I got the midi-chlorians." "I've got the goods." "The force is strong with me." "That is something I can feel." "But if I start opening breaches into other worlds, doing all this other crazy stuff Reverb was doing, then... what if this is how I become Vader?" "Dude, you're never going to become Vader." "You don't know that." "That is what happened to Reverb." "He learned how to use his abilities, and when he felt that, when he felt that power, he succumbed... to the dark side." "[chuckles]" "Look, I get it." "I..." "I really do." "Every time I've learned a new ability," "I've been terrified about what it might mean for me." "What it could do to me, you know?" "But you were there with me when I learned how to run on water, [chuckles] when I ran up a building, or traveled through time. [chuckles]" "Just like I'm gonna be there every step of the way with you." "You got something that Reverb never had, and that's Caitlin and Joe and Iris and Wells and me." "Friends who are gonna look out for you." "And we're more than just friends." "We're your family." "So what do you say?" "Ready to put those things on again, and go another round?" "Let's do it." "All right." "[exhales sharply] You're all set." "He won't even know it's there." "'Cause whoever said aesthetics aren't important." "Not me." "Let's go." "Hey, Cait, I know how hard this is gonna be for you, but we have to stop him." "I know, and I want to be supportive." "I just..." "I can't face Jay." "Or whatever his real name is." "What does that mean?" "Well, you remember when I was looking for his doppelganger, right?" "Yeah." "And you couldn't find him." "Because there is no Jay Garrick on this Earth." "His doppelganger's name is Hunter Zolomon." "Hunter Zolomon?" "Are you sure?" "Yeah, why?" "Well, because on my Earth," "Hunter Zolomon was a convicted serial killer." "That's Jay?" "No, that is Hunter." "Last public photo of Hunter Zolomon." "Instantly recognizable." "And people from my Earth... on my Earth, serial killers are an anomaly, so a lot of media attention to this." "There was a podcast." "When Hunter was 11, his father killed his mother right in front of him." "Father sent to prison," "Hunter grew up in the foster care system." "Years later he was convicted on 23 counts of murder." "23?" "That's, like, some real Hannibal Lecter type level." "After the trial, Hunter was sent to the Saint Perez Mental Asylum for the Criminally Insane... given daily electroshock therapy." "Cure him of his urges and then faded from view." "Until the night your particle accelerator exploded." "That's right." "The dark matter crept into the mental asylum." "I had thought... piping the explosion underground would limit exposure." "I was wrong." "All it did was create an unstoppable monster." "[ominous music]" "♪ ♪" "[electricity crackling]" "[rumbling]" "[grunting] [exploding] [ominous music]" "♪ ♪" "He's not unstoppable."

"Pretty sure, but just in case." "How do you use this?" "All right, so you aim it," " and then you pull the trigger." " Smart ass." "Barry and Cisco are in position." "Let's hope this thing works." " You ready, buddy?" " Yeah." "You've always believed in me." " Thank you." " You got this." "[futuristic humming]" "Reverb's doppelganger has increased his powers." "Hatred is a strong motivator."
