Barry: Why would you keep me here?
Cisco: Because I miss my friend.

Barry: What happened to us?
Joe: My daughter's life was taken. My son's...and then you left me, Barry. The last piece of who I was, left. Turned his back and ran away.

Barry: Tell me who he is.
Killer Frost: I'll never tell [taunting]. You're going to be so surprised when you find out.

Future Barry: Why are you here?
Barry: I need your help.
Future Barry: You're from before she dies, aren't you? You can't save her.
Barry: Yes, I can. And I'm going to.
Future Barry: No, you can't. Go home.
Barry: Just tell me who's in the suit. That's all I need. You tell me that and we'll be able to track him down. We'll learn his weakness. We'll stop him before he even tries. We'll stop him before he even tries. Just tell me who Savitar is.
Future Barry: I can't.
Barry: Why?
Future Barry: Because I don't know the answer. Sorry you ran all this way for nothing. You want some advice? Go home. Spend as much time with Iris as you can. Because pretty soon, we'll never see her again.

Cisco: Barry Allen [hugs him].
Barry: How did you know I was here?
Cisco: I had a feeling. A feeling I have not felt in a long time. So I hacked into the security cameras and I saw you fighting Top and Mirror Master in your OG suit with the white emblem. 2017 Edition, of course.

Barry: Caitlin, you can fight this.
Killer Frost: I know. But I don't want to.

Iris: I need you to make me a promise, okay? If things don't go our way. If Savitar kills me...
Barry: He won't.
Iris: If he does, Barry--
Barry: He won't.
Iris: If he does, Barry, promise me that you will be there for my dad. Don't let him push Cecil away. Don't let him spiral out of control. Make sure that him and Wally--
Barry: Stop. We're not going to talk about this. You're not going to die. I told you. I have a plan.
Iris: Barry, I need you to promise me, okay? I'm being serious. Promise me. Promise me you're going to make sure my dad is okay.
Barry: I promise.
