Chris is there in full Neon getup, (read: the neon clusterfuck of clothes that he calls a costume,) a little - but not too excited to rub elbows with some of the other hero types. He's bobbing around the park, usually with a cigarette or a beer in his hand - nothing illegal though (aside from the underage drinking,) he knows better to do that shit in an open area full of capes.

He's kinda taking stock of all the costumes and trying to remember names, but more than that one can rely on him to a) join in any fun looking games, b) be kind of bouncing like there's music playing even when there isn't, or c) showing off his fancy robot arms to any children who happen to stare. Where are the children? Not in the park but on the street? Did Chris leave the party just to go show a kid his arms? You betcha. And he probably gave them a balloon too.
