I have Mort, the boy who would not die. He'd avoid Mikhail, since his weird curse gives him a healing factor, and that's not something you'd want a doctor to know. Especially one with interests like Mikhail's.
Then, there's Jay. Jay doesn't like animals and would probably appreciate the fact that Mikhail isn't much of a people person. Mutual understanding. He might sometimes call upon Mikhail's medical knowledge for when he's got a sick or injured animal on his hands.
