You hated people, and it wasn't exactly because of any reason specifically. More like, you were born with this hatred. Medic could see it. Sure, he wasn't a psychiatrist in the medical field, but who could miss such a look? He's never seen such a cold stare. Which made him curious about you since the very beginning. Did your hatred make this job easy? It made him want to cut open your head and study your brain. He was so lost in thought, he didn't even realize he was staring.
