I think mine would work in something that's simple to learn and doesn't require much interaction with other people, like a shelf stocker, a mailman or a dishwasher (it's the kind of thing I'd like to find someday too)
Former black ops infiltrator, he now lives and works in a small truck pit-stop motel in Canada, near the Alaskan border. He works on the overall maintenance of the place and sometimes helps his co-workers fix trucks and cars. None of them know about his past life. He sometimes sneaks to the place where border services keep confiscated goods, and steals cash or jewelry. Old habits die hard.
Being a werewolf, he has an intense desire to tear people apart, so he decided to channel that violent impulse into something constructive. It helps that he is extremely arrogant. You have to be pretty arrogant to saw through a person's chest, take out their heart and believe you can fix it.
