No, I think I got it. He can't really possess me as easily as he can other, and if he tried to possess you I'm not sure what I'd do. But when I catch him and contact Jo, I'm definitely going to want your help then because even if I can get him trapped I'm pretty sure I can't keep him that way. Plus, I'm not exactly sure where the demon is going to go and if it somehow gets out, you're the best person around to do the whole slayage so it can't possess someone else.
