Harry will die for sure! and I think I know how.
one night he begins to study his book of magic as always...but this time he is really tired cause of working in the troll mines. he holds his wand in his right arm and the right arm is on the book. he quickly falls asleep and slides forward. the rest is pure physics(?): the wand penetrates his right eye and goes even deeper spilling his brains all over the book. then he will be mumified. the embalmers will thank him later cause they didn't have to do the egyptian ritual (the nose part).
the end
oh..and voldemort will get hermoine
ron will commit suicide
