Assgardian Loki / Lil Cap
Here's the thing. Sure, Cap was pretty well traveled. If well-traveled meant that he had been to war-torn parts of the world in 1942, anyway. When he was thawed out, he didn't exactly travel for "fun" and there were few places in the US that the Avengers Academy sent them. Most of the time, the bad guys liked to invade New York for some reason. It certainly wasn't for the Coneys and to catch a Broadway show. So, whilst enduring sweltering heat was tempting, the possibility of visiting Las Vegas was almost too good to pass up. When else would he get the chance?
Steve quickly changed into something presentable. He wasn't quite sure what the attire was. Sure, he could try to Sinatra it up like they did on the TV but that wasn't him. So, he settled on a pair of jeans and muscle shirt underneath a button up with the sleeves rolled up. He wasn't sure what the plan was. Were they going to wait by the door until everyone showed up or were they to just step through? Last time he went through the door, they'd done so as a group.
He stared at the door and waited. No one seemed to arrive. He bit his thumbnail, considering his options, and then decided to step through the door. He hoped that whatever waited on the side of the door wasn't completely insane. Maybe there would be people he knew already.
