Your reluctance is definitely understandable. I apologize, Doctor.

If it is any reassurance, my programming does not allow me to harm humans, not even in self-defence. The only exception to that rule allows me to non-lethally restrain a human who is assaulting another human.

I hope this puts you at ease. [Maybe it was also his programming, but he seemed genuinely concerned with Hank being uncomfortable around him.]
