True love. That's your pitch?

Captain Cold

Lyla: I really don't think you should be spying on me, Cisco.
Cisco: Is it really spying if we're friends?

Julian: Caitlin, I love you.
Killer Frost: I don't love you, Julian. I never did. [to Barry and Cisco] I never loved any of you.

Joe: I haven't seen him this happy in a long time.
Iris: Try ever. It's the first time he hasn't been weighed down by the tragedies of his past, you know? First time he's actually been free of them.
Joe: You don't want his memory restored, do you?
Iris: Dad, I can't say that seeing him happy and light isn't something that I have wished for him because yeah, it is.

Killer Frost: You should have never tried this without Caitlin.
Cisco: We didn't really have much of a choice now, did we? Also, don't refer to yourself in the third person. It's Caitlin. It's you. It's the same person. It's just confusing.

Iris: It's really nice to see you smiling so much.
Barry: How can I not? I'm going to be with you for the rest of my life.

Hi, I'm Barry Allen. You can call me Bart.

Barry

What am I going to have to become to stop him?

Barry

It's all coming together! [pauses] In the worst way.

Cisco

Savitar Barry: [to Barry]: I forgot to tell you. My suit's cooler than yours.

Cisco: It's over, Caitlin.
Killer Frost: Caitlin is dead.
Cisco: Not to me.

H.R.: You know how we said we were going to keep you safe?
Tracy: Yeah.
H.R.: Now I need to ask you to do something dangerous.
