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

Tracy: What are you doing?
Cisco: You mean save you from a burning, fiery death?

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

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.

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?

Cisco [to Wally]: We win and we lose as a team. I'm coming with you.
J'onn: Me too.
Cisco: Look, J'onn. I respect this whole special agent situation you've got going on. But this problem right here needs someone with...
J'onn: [transforms to his Martian form]
Cisco: ...green skin and a sick ass cape.
J'onn: Call me the Martian Manhunter.
Mon-El: I think you'll find that J'onn's a lot more than just a pretty face.

Man, how did you get out of that cell?

Cisco: What is it with you and musicals?
Barry: Everything's better in song.

Cisco: No way. I'm not going to vibe you there for you to watch your sister die.
H.R.: This is to help Wallace! To help him see what happens so he knows what to do in the moment.
Wally: Come on, Cisco, please. If Savitar's coming back and I'm the only one that can save Iris, I have to do everything I can to make sure that happens.
Cisco: And you're sure you want to do that? Because this is not something that you can unsee, Wally.
Wally: If this is going to help me save my sister, yeah, I have to see it. Please.

Here's a bonus. You get to spend extra time with this face [points to his face]. And who doesn't want to spend extra time with this guy?

Sometimes it seems like everyone else gets to have their love donut. Where's my love donut?

Change of plans! Barry, it's all about the running away.

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.
