- Bucky Barnes: Something's not right about Walker.
- Sam Wilson: You don't say.
- Bucky Barnes: Well, I know a crazy when I see one. Because I am crazy.
- Sam Wilson: Can't argue with that.
- Baron Zemo: The desire to become a superhuman cannot be separated from supremacist ideals. Anyone with that serum is inherently on that path. She will not stop, she will escalate until you are forced to kill her. Or she kills you.
- Bucky Barnes: Maybe you're wrong, Zemo. The serum never corrupted Steve.
- Baron Zemo: Touché. But there has never been another Steve Rogers, has there?
- Baron Zemo: Sam, you can't hold out hope for Karli. No matter what you saw in her, she's gone. And we cannot allow that she and her acolytes become yet another faction of gods amongst real people. Super Soldiers cannot be allowed to exist.
- Sam Wilson: Isn't that how gods talk?
- Sam Wilson: It's not a better place if you're killing people. It's just different.
- Karli Morgenthau: You're either brilliant or just hopelessly optimistic.
- Sam Wilson: Well, can't I be a little bit of both?
- John Walker: If you had the chance to take the serum, would you do it?
- Lemar Hoskins: Hells, yeah.
- John Walker: You wouldn't be worried about how it might... how it might change you?
- Lemar Hoskins: I mean, power just makes a person more of themselves, right? Karli Morgenthau. Steve Rogers.
- John Walker: And me?
- Lemar Hoskins: You already have three Medals of Honor. You consistently make the right decisions in the heat of battle.
- John Walker: Yep. Three badges of excellence to make sure I never forget the worst day of my life. We both know that the things that we had to do in Afghanistan to be awarded those medals felt a long way from being right. Being Cap is the first time I've had the chance to do something that actually feels right.
- Baron Zemo: Do we really have to litigate what may or may not have happened?
- Sam Wilson: There's nothing to litigate. You straight shot the man.
- John Walker: [enraged] WHERE IS SHE?
- Nico: It wasn't me... It wasn't me!
- [John proceeds to ram the shield multiple times into Nico, killing him as onlooking pedestrians watch in horror; all the while recording and taking photos of John]
- Nico: My grandfather, Lucas, he was a World War II resistance fighter. He always used to tell me, 'If you're doing something, and it makes you scared, it's probably because it's the right thing.' And he fought Nazis, so...
- Karli Morgenthau: Seems like good advice.
- Nico: You know, when I was a kid, I was actually a Captain America fan.
- Karli Morgenthau: Don't know if I should tease you about that yet or not.
- Nico: He made me believe that there was decent people in this world. I didn't think that there could be another Captain America until I met you.
- Karli Morgenthau: [taken aback]
- Nico: Back then, there was just good and bad. But the world's more complicated now. People are lost, they need a leader who looks like them, who understands their pain... Someone who understands that today's heroes don't have the luxury of keeping their hands clean.
