Fighting: Reeve can defend himself in a fight, though he has a body guard for a reason. In general, other characters can probably overpower him, but if he spots a chance to run, he'll take it.

Mind control, telepathy: Reeve has no natural defense against any sort of mind control and your character can probably get in his head pretty easily. Just check with me first.

Sex: In his younger days, Reeve went through a bit of a wild phase. As a result, he is relatively sexually experienced, more than one might expect of a giant nerd. That said, as he's aged, his sexuality has changed, and at the canon point I am taking him from, he strongly prefers a romantic or friendly connection to his sexual partners. He may be slow to warm up to the idea of Ariel at first.
