It is so stupid that they killed john off. That is the second time i had to watch him die on a show and he is so hot!!! No fair. i have this thing for older guys !!! I think that because sam and children like him have "special powers" the demon would want to take over there bodies and then they would have those powers to. They would be like superdemons in human form!! I have a feeling that there is still something wrong with Dean. he said he felt different and that worries me. i think the demon did something to him when he saved him.
