"You created Flashpoint and changed everything." "I went to the future." "My future self told me that he created time remnants to stop you." "But you slaughtered them all." "All but one." "Me." "I lived." "But a funny thing happened when I did." "You." "Joe." "Wally, Cisco." "You all shunned me because I wasn't the true Barry Allen." "I was an aberration." "A disposable hero." "Future you failed to mention that, didn't he?" "How did you become Savitar?" "I was broken... and alone." "I wanted the pain to end." "And that's when I realized the truth, Barry." "God feels no pain." "All I had to do was become one." "And I only need two more things:" "for Iris to die so that you are driven so far into the dark that I can be born." "And the other?" "It may sound ironic given who I'm talking to, but I'll keep that one to myself." "What happens if I kill myself?" "If I die, then you'll never be created." "Cause and effect's a tricky thing."

" "Voyager."" " I hate spinoffs." "That explains why Caitlin was willing to follow him." " He has a face that she trusts." " Half of one anyway." "So when the Legends found that message in the Waverider from old you saying "Don't trust Barry Allen,"" "it was talking about Savitar Barry Allen." "[chuckles] It's all coming together... in the worst way." "You said you made Savitar?" " How?" " Peep this." "Four years from now, future Flash creates... a time remnant to fight Savitar." "But Savitar lets that remnant live so that it can later become Savitar." "So once Savitar is imprisoned in the Speed Force, this remnant starts to go crazy." "And he goes back in time to the past... and becomes Savitar." "Creating the lie that he was the first speedster, spreading the myth and recruiting acolytes throughout the ages." "That doesn't make any sense." "Which came first, Savitar or the time remnant?" "It's a closed loop." "No beginning, no end." "It's just one endless cycle." "Classic chicken and the egg scenario, I think, eh?" "A time remnant, it's, um... it's like a duplicate of you, right?" "So it has your feelings, your memories." "So why would he want to hurt us?" "Why would he want to kill Iris?" "H.R., how's Tracy coming with the Speed Force trap?" "Good, yeah, good." "Slow." "Get her to speed up, all right?" "I'll do that now." "Can do." "If Savitar is a version of Barry from the future and he remembers everything that Barry does, how are we ever going to come up with a plan to stop him?" "What was he like?" "Broken." "You know... [sighs] all this time I thought that Savitar is this... monster." "It's hard to picture what might happen, and... it being you that..." "I..." "I know it's not you." "I'm..." "Part of him is." "He said it was like looking in a mirror, and he was right." "But not just the way that he looked." "It was... it was his eyes." "The pain that was inside them." "I've seen that in myself." "When I think about... how my parents died so violently... sometimes I want to repay that violence with more violence." "I want to make someone else... hurt as much as I do." "But you don't ever do that." "You're not him." "You're a good person." "But it's in there, you know." "That's in me." "That power, that pain, that's where Savitar comes from." "From loss." "From losing you." "You're not going to lose me." "Do you hear me?" "And we are going to stop Savitar." " You are not alone." "He is." " [sighs deeply]" "And he is not a god." "Jay told me that we're not gods." "He was wrong." "We could be." "Any speedster, and it wouldn't take much." "When the love that we feel in our hearts is drowned in anger... when the bad memories outweigh the good ones." "What am I going to have to become to stop him?" "Hey!" "Oh, bad time?" "No, man, what's up?" "I just came up with the best idea ever." "Either that or it's the worst idea ever." " But..." " It's an idea." "It's an idea!" "You want to give me a perm?" "It's not for your hair, Steel Magnolia." "This is for your brain, okay?" "I want to stop you from making new memories." "What are you talking about?" "Savitar knows everything we're gonna do because he remembers doing it." "He's a future Barry." "So... what if Barry can't remember what we're doing now?" "You want to mess with his brain?" "Just a little bit." "It's a minimal procedure." "It'll still be the same Barry you know and love, except he just won't be able to retain new information." "There's two types of memory, Allen." "Short-term and long-term." " Long-term is where you..." " Okay, Julian, just stop." "This is my presentation;" "I'm the expert here." "This is the part of your brain that retains new information before sending it to the cortex to be stored forever." "So what if we block that chain... with a magnetic disruption?" "So Savitar won't be able to remember whatever strategy we come up with to defeat him." "Which means he can't be two steps ahead of us anymore." "With any luck, we'll actually put him one step behind." "Beautiful." "Cause and effect." "Barry, what do you think?" "Let's do it." "Wait, wasn't Caitlin the expert on brains around here?" "She was." "But this is something we'll have to do without her." "I trust you." "You won't feel a thing." "Okay, let's get this show on the road." "The disrupter is attached to your hippocampus." "So, it's ready." "Okay, ready for zapping." "Can we not call it "zapping"?" "Ready to activate." "In three... two... one." " Sweet dreams, my beautiful boy." " Way to go, slugger." "Run, Barry, run!" "I have watched you be in love with Iris..." "Maybe we were meant to be together." "Okay, that should do it." "All right." "Right. [clears throat] How do you feel?" "I feel fine."

" You were?" "You..." " Yes." "Why can't I remember anything?" "Why can't I remember my name?" "Your name is Barry." "My name's not Barry." "I don't know what my name is, but my name's..." ""Bartholomew Henry Allen."" " That's not a good name." " Look, Barry..." "Are you sure I don't go by "Bart"?" "Can..." ""Bart" feels more natural to me." " Can we go with Bart?"

"That was the night that we realized how much we needed each other." "And look..." "I so wish... that I could take your dark memories away." "I wish... that I could make all of that pain go away, but I can't." "Okay?" "But what I do know, what I know, is that for every bad memory, there is a good one... that will get you through it." "♪♪ Soft dramatic music... ♪♪" "Run, Barry, run!" "♪♪" "Barry?" "I remember..." "I remember." "I remember everything." "I remember everything!" "Now for this fire." "♪♪ Exciting music..."

"Please tell me we're not gonna just let her walk out of here." " Now you want to fight?" " We don't want to fight you." "Can't really avoid that now, can we?" "Yeah, we can." "You can stay here with us." "We're your friends." "Your family." "Caitlin, I can fix you." "You already tried." "Well then, I'll try harder." "I don't care what it takes." "I don't care what I have to do." "I swear to you, I will find you a cure." "Caitlin, I love you." "I don't love you, Julian." "I never did." "I never loved any of you."

"When I was with my mom and dad again in Flashpoint, and I could've let it stay like that." "I could've let the memories of this timeline fade, but... if I'd done that, I would've lost Joe, and Cisco, and Wally, and Caitlin, and you." "Pain and darkness... it's a part of me."
