Tony only looked momentarily offended at Nick's advice before he was smirking at him and handing the flask back like he was willing to accept friendship again despite the fact the Nick slept with his mother (and giving something back was a rather poor peace offering).

Also not aware of the rules of this game, Tony could only shrug at Billy, assuming the same thing from the start. He would have to be more careful with his asking then. As for Billy's idols, he was left wondering just how old he must have been in Billy's universe for Wanda to be on the Avengers early enough to be a childhood hero. He tried to think about that for about a fifth of a second before he realized he needed to stop trying to compromise the timelines. Everything obviously wasn't as familiar as Billy and Cassie made it seem.
"I'm pretty sure I was completely infatuated with someone new every semester, but it was always little fleeting encounters that ended with me having serious talks with the principal for doing something inappropriate on the playground. School was easy, but I did a lot of it in a very short amount of time, so I never really made any connections and they were all just crushes. The clearest I remember was when I was maybe seven years old and my parents got a new place in the Carribbean and next door there was this major European supermarket chain CEO who had been there with his family for a few months, so they were like our host family that showed us around. He had three daughters, all of them red hair and green eyes, and it was that early that I started to question monogamy. How were you supposed to choose?"
