Before much longer, after that last, big crash, while everyone's awake and alert, they can probably hear someone coming up the stairs, and going down the hallway of the apartment building- as well as what sounds like an argument going on. Mostly Casey insisting that he doesn't need to be carried.

Then the door opens, and everyone can see the giant woman carrying the young boy over her shoulder, stepping inside and looking over at everyone, sitting around the room like they're waiting. "...Hm? You're all still awake? And... Greg? Is this some kind of late night get together?" She'd intended to just quietly drop Casey off, rather than being faced with a group of people here- but really, this is probably for the best. "Well, that's fine. Anyway, this young boy needs a bit of patching up. Do any of you know... human medical stuff? I think I heard something about one of you being a doctor."

She doesn't seem all that concerned or guilty about having gone out to fight things in the middle of the night.
