Here is a question - and I am still lost on the whole GoT ****e, but didn't when JJ was killed on the first night we had to burn the body in order for her not to come back to life or what not? Could "the others" still exist - the ones we have lynched because we have not burned their bodies? Not sure how the hell we would do that, but perhaps they can resurrect themselves on certain nights - I dunno this is a total shot in the dark...
There was the whole thing of keeping dead players in the game somehow - well if "the others" don't really die unless we kill them a certain way we might be screwed.
