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?

Savitar-Barry [to Barry and Iris]

Cisco [laughing]: You better have a Plan B. Because I don't think your Plan A worked out too well.
Savitar-Barry: Fix this.
Cisco: Fix what? The Speed Force Bazooka? I didn't name it. If I didn't name it, I didn't make it. And if I didn't make it, I don't know how it works.
Savitar-Barry: You know enough about it to alter what it does.
Cisco: Oh, I see. You want me to alter it. What do you want me to alter it into? Like a hair dryer? Or a waffle maker? Oh, I know maybe something that's going to fix that thin crust pizza you call a face.

Iris [reads future newspaper]: Iris West-Allen.
Barry: It changed back.
Joe: Does that mean what I think it means?
Barry: Yeah, Joe. The future's ours again.

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

Captain Cold: Make the plan. Execute the plan.
[King Shark appears]
Barry: Expect the plan to go off the rails.

Barry: This is not goodbye.
Iris: I know you're going to do whatever it takes to save me. Don't lose yourself in the process, okay?

Joe: You time traveled again?
Barry: Yes.
Joe: That's what got us into this mess in the first place.

Iris: It's really nice to see you smiling so much.
Barry: How can I not? I'm going to be with you for the rest of my life.

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: People we admire aren't always who we want them to be.
Iris: Well said.
