I'm BGK.... and why is no one open to the possibility that Harry wil die in the sixth book... maybe I've muddied the issue by spouting sh**e a bit, but look at this for a plot... Harry, desperate to reach Sirius, goes beyond the veil himself... he's dead! Hermione and Ron struggle and struggle to find a way to bring him back, unaware that Harry is on the verge of finding the secret of how to finally destroy Voldemort... alas, just as Harry and Sirius are nearly there, WHAM! He's brought back... the wrench of losing Sirius a second time is almost too much, and Harry becomes almost psychotically devoted to ending Voldemort's life... and incredibly angry with Ron, Hermy and Albus.... then, in book seven, Harry's friends watch him becoming more and more ruthless and single minded, and must work out how to stop him becoming a murderer... but too late for poor Draco....
Dan says Harry will die in the end... but if the last word of the last chapter of book 7 is "scar" -- what would be the need to say it if Harry is already dead???
and I also have a theory that either Ron or Harry will die, and that the other 2 will move mountains to try and bring him back... and will eventually succeed.
