Who do you all think is going to die in book 6?
I'm positive its Snape for two reasons.
1. He's going to be the new defence against the dark arts teacher since he wanted the position since the very beginning and considering that its jinxed he's got to die.
2. Voldemort doesn't like disobdience with his followers he'll want to teach snape a lesson for leaving his death eater gang. And he's a character who's closely linked to harry and then too sirius died because he purposely pretended to not know what harry was telling him about sirius when that ministry woman was present so he's got to pay for that.
Others will die too but snape being a more important character is the main person to go just like in book 5 sirius died
