Camping and the great outdoors are cool and all, but Dave is a modern teenager and so of course he wanders back to the rec area eventually. Space internet is as distracting as the normal/past internet, as it turns out. He's just stepping through the doorway when he catches glimpse of a strange shadowy mist disappearing around a corner.

Well. That sure looks like a suspicious thing right there.

As much as he has certain complexes over the whole hero-ing thing and personal issues about fighting and whatnot, Dave is still quick to leap to action when it appears necessary. Compartmentalize that shit and deal with it later, there's potential trouble afoot and no one else around to do anything about it. So there's barely a moment's pause before he's making a brief quantum leap forward to tail the shadow around the corner, hand moving for a shitty sword he doesn't actually have here. Shit, really gotta do something about that soon.
