Tony Stark: Sh*t!
Steve Rogers: Language!
(Some chatter and fighting later…)
Tony Stark: Wait a second. No one else is gonna deal with the fact that Cap just said “Language”?
Steve Rogers: I know. Just slipped out.
(Some more chatter and fighting later…)
Thor: Find the scepter.
Tony Stark: And for gosh sake, watch your language!
Steve Rogers: That’s not going away any time soon.
