Nora I shouldn’t have left things the way that I did. I want you to come home. We all do. You just have to stop working with Thawne.

Barry

Sherloque: She has a good reason to be mad with all of us
Cisco: What? Don’t lump me in with you two!

Cisco: I am clearly the Samantha of this group, right?
Iris: Okay, Miranda.

Sherloque: The Flash is already on the scene so for all we know the problem has already been solved.
The Flash: Guys, I have a problem.

It's what we do Barry. WE. She's our daughter, not just yours.

Iris

I’m only going to say this once. You don’t get to comment on us. Do it again and you won’t even make it to the end of that timer.

Iris [To Thawne]

I know how Barry can be, but you two are like the Megan and Harry of superhero royalty!

Ralph

You talk about making decisions based on emotion. Look in the mirror.

Barry [to Iris]

Barry: Damnit Iris she lied to us for months!
Iris: Yea and she explained why.
Barry: That she was working with Thawne?! That honestly doesn't bother you?
Iris: No, it doesn’t.
Barry: Maybe if he killed your mother in front of you, you’d feel differently.
Iris: Maybe you feeling differently Barry, is why we should have made this decision together.

Iris: We have been through so much crap. We have been through so much therapy, but you are still making decisions based on your emotions!
Barry: Because I’m right this time!
Iris: Flashpoint? Going to the speed force and leaving me? Were you right those times too?

I’m a father too, and I have a daughter who I love more than I ever thought possible. I would do anything for her and I know you would do anything for [Grace]. So do it.

Barry

Nora: From the movie Breakin'
Cisco: Yeah!
Nora: I've seen Electric Boogaloo, too. I've seen them both like, a hundred times.
Cisco: Wooooow, fangirl!

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

Barry: How long do you think he'll stay asleep?
Captain Cold: I like Shark Week. I'm not a marine biologist.
