Everyone who is helping Harry is going to die -- I think.
There has been a trend with the books so far...that is, slowly those on the helping side of Harry have kicked the bucket , per se lol.
People say she was awful in killing off such a major character in the 6th book like that...well, she had to. The poor guy was helping Harry out.
I think her main goal is to have Harry alone with Voldemort...I think that she feels it is completely important for it to be a one on one battle.
With that said -- I can definitely see a "blood bath" in the book -- too many people are on Harry's aggressive side (helping him out).
