Caitlin: That kind of power, it could take out another Earth.
Chester: Or another universe.
Allegra: Wait, what? Are we about to have Crisis part two?
Cisco: No, no. There's not enough anti-matter for that, thank the sequel gods.

Abra: I see you're finally Mecha-Vibe.
Cisco: Mecha-Vibe? I know he did not just name me.

Chester: Wait, hold on, hold on. Is this thing, like, a time capsule? Ooo, maybe like a TARDIS.
Cisco: P-Runk, you picked a hell of a day to start your CCPD Consultant Internship. Yeah, this is definitely a time traveler.

Look, there are people out there just like you who wish they hadn't been a part of this story. But they were. You're their voice. So try again, for them.

Allegra

Usually we have to kiss first to make the ground shake.

Iris

I may be the Paragon of Love, but that's only because you're my heart. Please, come back to me.

Barry

Barry: Of all the Wells, you were the one I wanted to meet the most. I'm Bar-
Harrison: Barry Allen. I know. The other Wells might be gone, but they left an imprint, memories. And so let me just say, whatever's wrong. Let me help you because they would want me to.
Barry: You can't. This enemy that we're facing is all-powerful, plus my speed is gone.
Harrison: Aren't you the Paragon of Love? Look, anyone could save the world with their speed, with their might. But it takes a real hero. A once-in-a-lifetime hero to do it with his heart.
Barry: What is that supposed to mean?
Harrison: It means run, Barry. Run toward love.

I have a theory that went Nash and all the other Wells were removed from the timeline, the universe required a balancing act. One Wells to make up for all those lost. Isn't that cosmic?

Harrison

Barry: And what happens to us?
Eva: You adapt to your new world. Same as I did. Don't worry, Barry. I'm not going to kill anyone. I'm not your enemy. What I am is a mother to a newer, better world.

Boss, you have to get better. The Citizen doesn't work without you. So, just, please, come back, okay? Cause we're not giving up on you. Especially Barry. What you two have is amazing. No matter how strong you both are on your own, you're even stronger together. Don't let Eva McCulloch end what you guys have.

Allegra

Why does it always feel like for us to win, some of us have to lose?

Cisco

Barry: Your emotions are making you irrational.
Cisco: And your lack of them are making you wrong!

Harry

Eva: Why do you keep interrupting my mission, Flash? I told you, we're on the same side.
Barry: If we're on the same side, then give me back my wife!
