As she spoke, she gave him that look that made him feel like an animal at a zoo. She seemed to be actually concerned, or just really good at acting, when she asked if he was okay. But Sasha was no sick pet, in need of tending to. He was a perfectly healthy human being who really wanted to be left the hell alone. 

Her comment about him looking pale was almost funny. He was [i]always[/i] pale. 

"I'm fine," He said curtly. He paused, then added. "I was kind of in the middle of something. I'd like to finish before dinner." Sasha made it blatantly obvious that he had no interest in talking to the doctor. She creeped him out a little bit and he really wanted nothing to do with her. Whatever scheme she was getting at here, he planned to resist every step of the way. And if his incidents with his meds were anything to go by, he was [i]very[/i] good at resisting.
