Wells: So, potentially, these two guns could cancel each other out.
Cisco: Yeah, but to do that you'd have to get them to cross streams.
Barry: You mean like Ghostbusters?
Cisco: That film is surprisingly scientifically accurate.
Wells: And very funny.

Look Barry, Cisco and I will work with Joe and the police and devise a way to catch Cold; yes, I said it, as soon as it came out of my mouth, Cisco, I heard it.

Harrison: The reason I know all this is because your powers are almost exactly the same as The Flash!
Yellow: Well, I'm not like The Flash at all. Some would say I'm the reverse.

Joe: Look, Barry, me and Dr. Wells have spoken and we think it would be best if you weren't here for this.
Barry: What are you talking about?
You're too close to this.
Barry: Well maybe you're not close enough! If you hadn't been too scared and warned me that he was here weeks ago, I would have been prepared for this.
Harrison: I think we can all appreciate Joe's concern for Iris, Barry.
Barry: That's why I have to be here! I'm the best chance at catching this guy!
Joe: Not in this state.
Barry: This man stabbed my mother through the heart and sent my father to prison for it. This is MY fight!
Joe: Not today, son.

Harrison: Mr. Queen, I met your father once, at a charity event. One of the things we spoke of was you. I think he'd be very proud of the man you've become.
Oliver: Thank you. Please, call me Oliver.

None of us can stop, Barry. Fortunately, Felicity knows somebody who can. I think you better call back Oliver Queen. We're gonna need The Arrow's help.

Harrison: Felicity, I like to surround my team with known quantities. That is because I find the unknown to be toxic. Dangerous. Arrow is unknown.
Felicity: I can assure you, Dr. Wells, that he's not dangerous. To us.

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.
