Unsurprisingly to maybe anyone who had ever met her, Kennedy was chomping at the bit for something to do, or more specifically something to do that didn't involve hitting her friends (and finding out they were demons, but that part was applicable even outside of this situation) because you couldn't hit fog, damn it. A couple of further calls to her Watcher hadn't dug up anything even remotely useful to the situation, and that contributed to her, uh, mood.

She could have replied to the text, but actually barging over to Arthur's room burned some of that restless energy, so there she was, pounding on the door.
