Barry: I think that you were right about Harrison Wells.
Joe: Which part?
Barry: All of it.

All you proved today, Mr. Ramon, is that you're human. All you proved today is that you loved your brother. And the reason that we all want you to stay is that we love you, too. Now, I am not a parent, but in many ways you have shown me what it is like to have a son.

Harrison

Joe: Let me ask you something. Who do you love?
Iris: I mean I love Eddie.
Joe: OK. You need to make them believe that because right now I'm not sure that either one of them does.

Captain Cold: I like you kid. You're smart, you pulled yourself up from humble beginnings, you seem like a good brother.
Cisco: You, too.
Captain Cold: Debatable.

Barry: I don't understand. I thought that I was helping people by stopping Mardon.
Harrison: Yes, but this new ability of yours, Barry, is dangerous and you only traveled back in time one time. What if you traveled back in time decades, centuries? Imagine the havoc you could wreak.
Barry: But I will have the opportunity to travel back in time in the near future to save my mom. Are you saying I shouldn't?
Harrison: I'm saying how many more people could die if your mother lives.

Captain Cold: My sister needs a weapon. Something that suits her personality.
Lisa Snart: Make me some pretty and toxic. Like me. How about something with...gold.

Tell the rest of the Santini family that there's a new godfather, and his name is Cold.

Captain Cold

Harrison: No! Do not tell me. I do not want to know anything about the future you experienced. Nothing.
Barry: Dr. Wells...
Harrison: Barry, time is an extremely fragile construct. Any deviation, no matter how small, could result in a cataclysm.

[to Iris] I am so sorry. I didn't want you to find out this way.

Barry

Iris: Listen to me. Ever since the night that you told me how you felt, I have not been able to stop thinking about you. At first I was really mad, and then I realized that the reason I couldn't stop thinking about you was because I didn't want to.
Barry: I've never stopped thinking about you.

Do you know how hard it has been to keep all of this from you, especially from you, because the truth is I've grown quite fond of you and in many ways you have shown me what it's like to have a son. Forgive me, but to me you've been dead for centuries.

Harrison

Cisco: Joe was right. You were there, that night, 15 years ago in Barry's house. You killed Nora Allen.
Harrison: It was never my intention to kill Nora. I was there to kill Barry.
Cisco: Why?! You're his friend. You've been teaching him how to...
Harrison: Go faster, I know. It's a means to an and and I'll tell you why. Because I have been stuck here, marooned here, in this place for 15 long years. The Flash and The Flash's speed, is the key to returning to my world and to my time and no one is going to prevent that from happening.
Cisco: I can help you.
Harrison: You're smart Cisco, but you're not that smart.

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.
