Caitlin: He's the only family I have left.
Barry: But Caitlin, that's not true. We're your family too. And we're only asking you to keep an open mind because we care about you. Especially Cisco.

Cisco: Iris West-Allen, I know badassery when I see it. And that was raw, unrefined, cage-free, non-GMO badassery.
Caitlin: You dove off a building!
Barry: To save me!
Iris: Yeah, I guess I kinda did.

Barry: Nora, you gotta snap out of this.
Nora: What I've got to do, is kill you.

I have enough faith in you for the both of us.

Barry: Okay there's no telling the ripple effect of this change or the future Nora's going to return to. We gotta catch this guy fast.
Cisco: You mean catch the guy future us can't catch? Right. I thought beating The Thinker was hard.

Cisco: Thanks Fangirl, you saved my life.
Nora: I did good?
Barry: You did great.

Barry: Nora wait what are you doing?! You can't touch that, you'll contaminate the evidence!
Nora: Sorry, you mean you don't have a scene wide modified bi-sonic frequency field to avoid cross contamination?
Barry: I don't even think we have some of those WORDS yet!

DeVoe: You beat me!
Barry: No. We beat you.

Barry: Yeah, yeah it's Ralph. He's alive! Wait, how are you even here?
Ralph: How are you here? Did DeVoe get you?
Barry: No, no. He didn't.

Barry: Yeah, I just don't know if it's the best idea to send people out there to do our jobs for us.
Iris: We're inspiring them Barry. I mean we could be the ones to show them how to do the right thing.

Cisco: And if you don't take us, we'll die anyway. Our brains get wiped, and that's it. That's the end of the world.
Barry: No, losing both of my best friends, and it being my fault...that's the end of my world! You may think it's worth the risk, but I couldn't live with myself.

How do we explain me at the wedding? Do I sit bride-side or groom-side?

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

You are my lightning rod, Iris.
