And if so, is it just going to be Ben and The Ghosts?

I don't think Ben can live with himself knowing what he did to his family, but in an ironic twist he will somehow die without getting to be a ghost in the house.

But what's up with the ghosts? The nurses and the burnt up kids and the little pricks from the 70's all appear with their burns and wounds and whatnot from when they died, but why isn't Tate covered in bullet holes?
