Guy meets girl. Guy devours girl's soul and takes over her body. Guy in girl's body gets tied up and kidnapped by other guy. Other guy brings first guy to new girl. New girl wants to brainwash first guy.
I don't want that to happen. Dodgy can help me. Or if he can't help me, he can show me a few tricks, maybe, or exchange tips about some great bodies to snatch - I don't know. I've never met anyone else who can do what I can do. Or has any of the same kind of...problem. Sure, it's probably a long ways away, but I'm good at getting around, no? And it's not like someone's going to mug me along the way. Not successfully, anyway.
And even if he wouldn't help me normally, I think breaking him out of a brainwashing camp is a pretty good excuse to tell me what he can do.
