Cisco: Look at this man.
Other Harry: I see him.
Cisco: Is he not one of your own? Are you telling me you're going to betray one of your own because he doesn't meet some arbitrary intellectual standard?

Don't be afraid, Cisco, a great and vulnerable destiny awaits you now. I only hope that as you're living a great adventure, that you remember who gave you that life and that it was given out of love.

Eobard

Barry: I want to kill you right now!
Harrison: I used to know that rage. I used to feel that rage every time I looked upon you and now I know what Joe and Henry feel when they look on you with pride. With love.

Barry: Why did you kill my mother?
Eobard: Because I hate you. Not you now, you years from now.

Eddie: You know they're gonna find me. And you. You're not as smart as you think you are.
Harrison/Eobard: Oh really? 'Cause I'm a genius where I come from. Imagine how smart that makes me here.
Eddie: The future? With a name like Eobard, I guess you'd have to be.
Harrison/Eobard: Eobard is a distinguished name for a distinguished member of a distinguished family.
Eddie: It's depressing to think all of my descendants are as crazy as you.

Eddie: I don't suppose you brought lunch.
Harrison: Do you know human beings can survive up to two months without food?
Eddie: Is that how long you plan on keeping me here?

Harrison: My name is Eobard. Eobard Thawne.
Eddie: I don't understand. Why do you have my name.
Harrison: Because we're family, Eddie.
Eddie: Funny. I haven't seen you at any weddings or reunions.

Barry: You know, I couldn't have done any of this without you.
Harrison: I feel the same way about you.

Barry, listen to me. You need to move your arms faster! I believe in you, Barry.

You're good, Barry Allen, you're very good.

Harrison: Your ATOM suit is quite the technological achievement, Mr. Palmer. I'm impressed.
Caitlin: And he is never impressed.
Ray: Thank you, but I can't quite seem to keep it up.

Harrison: What exactly are we waiting for, Ms. Smoak?
Felicity: [points to the sky] That there!
Caitlin: Is that a bird?
Cisco: It's a plane...
Felicity: It's my boyfriend
Ray: Hi! [waves] I'm Ray.

The Flash Quotes

One mystery I cannot figure out is why some people come into our lives and why some people go. Others become a part of you. Some friendships feel like they'll last forever and others end far too soon. Not every friendship is meant to last forever. What does last forever is the pain when that person is gone.

Barry

Harry: I am continually amazed by the similarites of our two worlds.
Joe: You got talking gorillas on your earth, too?
Harry: Oh yeah.
Joe: Whew. Remind me never to go there!
