I am fine with whatever decision you guys make in terms of father. I have a really open mind for this roleplay. I also like the idea of the boy possessing the next door boy it should be good plot. Sometimes I think its just better to invent things as they go. Nobody can predict what is going to happen and telling how stuff would get its a bad idea since nobody knows what will happen. So I suggest to start the game without the father (unless omeone plays him) and see where it goes. I think also it would be cool if my char has claustophobia (afraid of closed spaces) so when she gets trapped she would really freak out.
