You always did look good in red.

Henry

Joe: I don't know why he's helping us. All that matters is that he is.
Barry: I can't lose my dad, Joe. [breaks down in tears]

Look, whatever else he is, he is Harrison Wells. You love science, he is science. It's like you made best friends with Einstein.

Barry: I think that you were right about Harrison Wells.

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.

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.
