Clam down, electric guy.

Ignore him, it's his first crossover.

Looks like you're dead.

Killer Frost: Hey, stranger.
Caitlin: Hey.
Killer Frost: Well, we sure have a lot to talk about.

Caitlin: He's the only family I have left.
Barry: But Caitlin, that's not true. We're your family too. And we're only asking you to keep an open mind because we care about you. Especially Cisco.

You are Cisco Ramon. Genius engineer, prodigy hacker, and the mechanic who built a cold gun that could stop a speedster. And you're my friend. My friend who went out there and hurt himself today just to try and help me find my dad. And that wasn't Vibe. That was Cisco. That's the guy I need.

Cisco: Iris West-Allen, I know badassery when I see it. And that was raw, unrefined, cage-free, non-GMO badassery.
Caitlin: You dove off a building!
Barry: To save me!
Iris: Yeah, I guess I kinda did.

Iris: Whatever the future brings we’re gonna deal with it when it gets here, and change it if we need to.
Cisco: She’s right. If there’s anything Team Flash is good at, it’s handing the future it’s own ass and then some
Caitlin: What he said.

Cecille: You've done this before, right?
Caitlin: Yeah, a couple times... In med school.
Cecille: Med school. Right...

Caitlin: So do we have a deal? You'll give me the splicer as soon as we recover it?
Amunet: I'll even tie a little bow on it.

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.

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.

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.
