Marian's starting to get the feeling he's implying something, and doesn't like it. The one advantage to that though is that irritation replaces some of the panic, although she's still going to keep him more in peripheral vision rather than look directly.

"You look like someone who's dead. Reanimated as s-some kind of v-vessel for s-s-s.... s-something else." Her voice rises again, perturbed. Not like that was a thing that actually happened. Nope. Let's not talk about that directly. "D-don't you think that bothers people? Maybe you c-can't help what you look like. And m-maybe some of us have a good reason for being ...s-s-suspicious."

Suspicious is one way to put it. Instead of, y'know, panicked.
