Peter and Tony Stark
Peter wasn't really big into illicit activities anyway. He'd tried some beer at Steve's birthday party, and hadn't liked it very much. Aunt May hadn't been that strict, but Peter had never really had much interest in that sort of thing. He was more interested now than he'd ever been, but if it all tasted like beer? No thanks.
"No, no I've never been here before. I've always thought it sounded like a fun place to visit, though." Peter wasn't in it for the gambling and debauchery. But there were other things for a kid to do in Sin City. Arcades, indoor go-carts, roller coasters on top of casinos... escape rooms? All kinds of cool stuff.
"I dunno. I hear he's supposed to be around here somewhere. Are you having a good time? I mean, what have you been up to?"
