It's surprisingly easy to break into Stark Tower, given all the supervillains. He left one of the windows unlocked. It's like he's asking for Chris to come in. Even if this plan doesn't work out (which it will, it's a great plan, Rachel agreed), he should probably come back just to steal some shit.
The room he breaks into has two teenage boys studying in it. Good sign, although if Asher makes Chris go to school their relationship won't be as long and mutually beneficial as Chris would have hoped. The boys are both tiny. They look like Chris could break them apart with his hand. Maybe Asher has a type, which would be disappointing. On the other hand, maybe he's looking for a change.
