It sounded like destruction, and Matt was always fine with that.
Well, that wasn't strictly fucking true. It didn't sound like significant destruction, though. On the other hand, it was in a room that he would've sworn was unoccupied, and he couldn't quite place it, so he knocked on the door. He was, he could admit, pretty much hoping that the rolling sound was something awesome.
He didn't really expect the door to actually open.
