Sam blinked, as if he wasn't sure she was serious, then gave her an arrogant smile.

"Cat, no offense, but I'm the medicine student here. I think I'm more qualified to evaluate my own health than you are. Biology isn't something you learn through prayer."

She frowned but didn't answer. Sam immediately realized he might have actually hurt her feelings, but was too proud to apologize. He looked at her blankly for a moment, before shrugging his shoulders.
