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

Admission here is so easy.

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

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

Can you please stitch me up? Because I think I need to pass out.

I was so focused on not hurting you as Killer Frost that I forgot I could hurt you as Caitlin Snow. And for that, I'm very sorry. So I understand if you don't trust me anymore, but maybe you can find it in your heart to forgive me.

Cisco: It looks like things between you and Julian are a little [pauses for effect] frosty.
Caitlin: [gives him a dirty look]
Cisco: It's too soon for the cold puns, huh?

They're being drained. The guy who did this to them [gestures to Barry and Kara]. I think he's stealing their powers.

Caitlin: It's not you.
Julian: It's impossible to tell. Savitar could be controlling me and none of us would know about it. None of us. Not even me.
Caitlin: But this time we know who it is.
Julian: How?
Caitlin: Because. I'm the one who betrayed everyone.

Caitlin: Julian, you can't change what happened to you. It's not your fault.
Julian: You keep saying that. But it is my fault. People are responsible for their own actions. To say otherwise is just a way to make yourself feel better.
Caitlin: Is that what you think I'm doing? Making excuses for things I've done in the past?
Julian: [doesn't say anything]
Caitlin: You know I'm really starting to regret bringing you in here.

Caitlin: You know, I used to think Barry was overreacting when he complained about sharing a lab with you. But now I understand his frustration.
Julian: Believe me, no one is more frustrated than I.
Caitlin: You do realize it's possible not to be a jerk all the time, right?
Julian: Yes, yes.

Caitlin: Are you asking her on a date?
H.R.: Are you kidding me?
Cisco: I am negotiating.

The Flash Quotes

Ramsey: You know, I don't understand you Barry. You march towards death without fear, just like mum. Where is it you get your strength?
Barry: Probably the same place she did, people I love.

Where I came from, I was a speedster like you. They called me The Flash.
