I always love their first encounter. He clearly knows her, so knows that she is a doctor. She so authoritatively tries to move Barnabas, but he won't allow it. Speaking as one doctor to another, she can't be too vague. He asks her quite specifically about Barnabas' condition and her treatments, and there isn't too much she can say. He reveals quite specific knowledge of it, yet she obviously can't confirm it. She has to try to protect Barnabas and pretend not to understand what he is saying. Yet, she says enough to reveal it to him (although he clearly seems to know without that). Their sparring is a lot of fun.
