As he always has as long as they've known him, as soon as the group is moving at speed, Kurt is galloping along the walls and ceiling on all-fours, effortlessly scrambling over anything in his way and keeping up with the other two. This is where he is when that shudder moves through the ground. His eyes widen, tail lashing. "Was im Himmel?"
He only spares a brief glance in Trista's direction, because he's going to have to pay attention to all this fighting in a moment, here. "Who, who is back, what was that?"
Answers will have to wait, of course. The demons are almost upon them, and getting their entire group together, in one place, is more important still. Kurt found himself baring his teeth as the first wave closed on them, eager to work out months of pain and despair on the wretched things. He doesn't intend to leave a single one of them with all its limbs attached.
