Steve: I hate you.
Tony: I hate you too.
Steve: I hate you more.
Tony: No, I hate you more.
Clint: I know you want to marry each other, you fools! Just do it! Marry each other and adopt children and a movie about how you two met and write a book too!
Clint: Do it!
Tony: Propose me!
Steve: Marry me?
Tony: Do it right.
Natasha: [gives Tony a terrifying smile]
Tony: I-I mean… Yes, now let’s adopt kids and do a movie and write a book and die together.
Tony: Natasha is one badass, crazy, super bitch
Natasha: [sneaking up behind him] Tony if you just said I am one badass, crazy, super bitch you are correct.
Natasha: [talking to Tony and Bucky] Did the two of you really think you were going to get away with this?
Tony: Well… It would be stupid to say yes now.
Tony: Hey, guys, check it out. Pepper sent me the paper.
Natasha: Let’s see it.
Clint: Oh, yeah, that looks good.
Natasha: You make a very attractive couple.
Tony: Yeah, we look great together.
Bucky: We really do.
Tony: Imagine what our kids would look like.
Bucky: We don’t have to imagine.
Steve: I’m marrying him.
Bucky: We’ll see.
Tony: Ah, I’m really starting to feel this in my shoulders. You couldn’t give my a back rub, could you?
Natasha: That’s right; I couldn’t.
[Natasha is stabbing the air between Steve and Tony]
Steve: What are you doing?
Natasha: Trying to cut the sexual tension between you two. Unfortunately, it isn’t working.
Tony: How was I?
Natasha: Scattered. Annoying. Alternating between genius and bad puns.
Business as usual, then.
Tony: Okay. Now I’m scared.
Natasha: It’s okay, I’m here.
Bucky: Nat, you’re what’s scaring us.
