Kurt doesn't look at the Doctor, just sitting with his arms around himself in the corner. His eyes look off to the side to stare at the wall instead. His tail is curved around, laying on the floor. It taps against the floor now and again.
He did what he was supposed to do. Now he just waited for orders...but internally, his mind was edging towards thinking about how wrong this situation felt. He pays the Doctor as much attention as if he was never there. His three toed feet and hands are visible, still wearing his circus costume due to the fact he has no other clothes.
