Hm... well, one thing that John usually has to deal with, is the fact that the spirits annoy him, popping up at the most inopportune times from his experience, and generally ends up yelling at them, startling people. Another thing, is that an organization called Iscariot is after him. They are after alot of people, so they only send a few people after him at a time, but they are generally rather skilled, and good at ambushes. THey hunt down non-humans that they feel to be 'evil'. They are really just bigots. So that can factor into... whatever, lol. He also has some shitty luck at times. Like just bumping into a drunk who happens to decide it's a good idea to stab him repeatedly.
