edit: at 0:26 they hear a strange thud, we see no physical force that could have made that noise. the girls scream.
at 0:29, the cameraman comes out of the room the noise came from and says "it's just stephen".
... but stephen didn't go with them and ke$ha hasn't spoken to him in ages.
how could it have been stephen? did he die? how did he die? if he did die, why is trying to haunt kesha?
