Here’s my theory. The prophesy is not about Harry but about Draco. Sure, he was born in early June rather than the “end of the seventh month” but either they miscalculated based on using the wrong calendar, or Draco’s mother had an early C-section because she didn’t want stretch mark (because she’s a little narcissistic :)). The mark that Voldy leaves on his opponent is not Harry’s scar but the dark mark that Voldy put on Draco. Snape has spent the past seven years protecting Draco so that he could fulfill his destiny and he kills Dumbledore so that he can escape with Draco and protect him. What???
OK-here’s what really happens; Snape is actually good although he legitimately hates Harry. He ends up sacrificing himself to help Harry kill Voldy. Hagrid also dies. All the couples end up together and have a nice mass wedding at the end and they all live happily ever after.
Now for the questions that remain unanswered for me after reviewing books 3-6:
-How does Harry get the Marauder’s Map back at the end of Book 4. When we last saw it, it was in the hands of Barty Crouch junior and Dumbledore (who Harry had carefully prevented knowing about the map in the past) has become aware of it. Does Dumbledore just give it back to Harry?
-Harry has been banned from Quidditch for life in Book 5. Does Hogwarts just randomly reverse the punishment?
-There is evidence of children casting spells without wands, and Harry has also done magic without a wand. Why is it that when a powerful wizard like Dumbledore loses his wand, he is completely helpless?
-There is supposedly excellent protection around Hogworts, to the extent that nobody can apparate within the grounds. However, there is apparently no protection against the flue network before Book 5. In addition, wizards can fly in and out of the grounds without any problems. What kind of crap security is this?
-At one point in Book 3, it is mentioned that the front doors of Hogworts are locked every night. However, students apparently come and go freely at other times. How?
-People in portraits can come and go between each of their portraits. Why do some leave blank canvases, yet some maintain portraits in both places?
I’m sure there are more but this will do for now.
