Scott/Steve
Pretty much. Although I didn't know you had any... specific skill set in our world until Sam started describing the fight. We don't have the same roster they have in the other world. You could've just been Scott Lang, regular guy. I wasn't sure.
Who stops on the roof to prove they're there for good reasons? I mean, come on. What did you think would happen? Stark can do whatever he wants with his property. This just happens to be my base. ... How many people know where it is? What were you after, anyway?
