He'd expected her to do one of two things, upon finding herself atop him; she could either recoil from the contact and get back over to her side of the bed, or else she might take advantage of the situation to try and get into a position of power and wrest his wand away from him. He was not prepared for the middle ground between the two, and he was rather baffled when she simply froze, staring at him like an animal caught in a trap. She looked like she didn't enjoy being draped across him, but it wasn't as though he had put her there, or as though he was keeping her there.

After her previous violent reaction to his turning over, though, he wasn't sure he wanted to just shove her away. Instead, he took advantage of the quiet to ask, "What are you doing?" It might have been a question, but his tone was a mixture between a demand and an accusation. His patience with her game, whatever it was, had worn thin.
