Pepper Potts: We got really lucky.
Tony Stark: Yeah. I know.
Pepper Potts: A lot of people didn't.
Tony Stark: I can't help everybody.
Pepper Potts: It sort of seems like you can.
Tony Stark: Not if I stop. I can put a pin in it right now. And stop.
Pepper Potts: Tony, trying to get you to stop has been one of the failures of my entire life.
Tony Stark: What we needed was a suit of armor around the world! Remember that? Whether it impacted our precious freedoms or not, that's what we needed!
Steve Rogers: Well, that didn't work out, did it?
Tony Stark: I said we'd lose. You said, "we'll do that together too." Guess what, Cap? We lost, and you weren't there. But that's what we do, right? Our best work after the fact? We're the Avengers? Not the Prevengers, right?
Rocket: You think you're the only one that lost people? What do you think we're doin' here? I lost the only family I ever had. Quill, Groot, Drax, the chick with the antenna - all gone! I get that you miss your mom. But she's gone - *really* gone. And there are plenty of people who are only *kinda* gone. And you can help them.
Bruce Banner: If we do this, how do we know it's going to end any differently than it did before?
Carol Danvers: Because before, you didn't have me.
James Rhodes: Hey, new girl? Everybody in this room is about that superhero life. And, if you don't mind my asking, where the hell have you been all this time?
Carol Danvers: There are a lot of other planets in the universe, and, unfortunately, they didn't have you guys.
Steve Rogers: You know, I saw a pod of whales when I was coming in, over the bridge.
Natasha Romanoff: In the Hudson?
Steve Rogers: Fewer ships, cleaner water...
Natasha Romanoff: You know, if you're about to tell me to look on the bright side - I'm about to hit you in the head with a peanut butter sandwich.
Steve Rogers: Sorry, force of habit.
Thanos: I used the stones to destroy the stones. It nearly killed me, but the work is done. It always will be. I'm inevitable.
James Rhodes: Let's search this place with a search party. He has to be lying.
Nebula: My father is many things. Liar is not one of them.
