Book 7 prediction!
Okay, I'm blogging this one more with a view to pointing back to it
after book 7 is finally released and saying "look, I had it 3 days
after Prince was released!"
Click through for the prediction. MAJOR SPOILERS for HBP inside.
We know that Voldemort was looking for items belonging to Ravenclaw and Gryffindor to complete his Horcrux collection.
We know that Dumbledore believes that "the only known relic" of
Gryffindor's - presumably the sword - is safely in his office. Note
that he uses the singular here.
We know that Voldemort showed up at Hogwarts - in Dumbledore's office
no less - to request a job that he knew Dumbledore was not going to
give him. Dumbledore called him on this, but he gave no true reason. We
also know that his hand flicked to his wand in Dumbledore's office.
But - and here's the crucial part - we know that Dumbledore is wrong that there's only one relic of Gryffindor's remaining in existence. Remember the Sorting Hat's song from Phoenix?
"Twas Gryffindor that saw the way,
He whipped me off his head:
The founders put some brains in me
So I could choose instead."
So here's the prediction:
While Dumbledore may have forgotten that the Hat is a Gryffindor relic,
I'm sure Voldemort didn't. I'm not sure how exactly he managed to kill
somebody (necessary to make a Horcrux) with his hand and wand in his
pocket in Dumbledore's office, but I'm absolutely convinced that that's
what he did.
The Sorting Hat is the Gryffindor horcrux that Harry's searching for!
