Iron Man: And who are you two supposed to be?
Wanda: Oh, um, we're brother and sister. Our father is a powerful mut--er, a different sort of fellow who was born with interesting magnetic powers.
Quicksilver: Yes, and because our father was born with powers we were also born with powers. Kind of like a genetic thing.
Iron Man: So you're saying there are people out there born with powers? I built my suit, Banner was hit with gamma radiation, Thor is a God, Cap was a scientific experiment... but there are others out there with mutations?
Wanda: Don't say that word! Are you crazy!
Iron Man: Why? What do you mean?
Quicksilver: You guys had a big fight with Loki in New York a while ago, right? Well, wasn't there something missing? There's a hero out there that famously makes his home in New York. Pretty iconic. You can't say his name for the same reason you can't say mutant.
Iron Man: Yeah, where was that dipshit Parker by the way?
Quicksilver: For chrisakes!! For a genius you're pretty stupid.
Iron Man: Well, it's not like Reed figured it out either.
Quicksilver: *facepalm*
