Spoilers? I do this because I want to know...
Little bit of possible Book 7 spoiler for everyone to think on. In recent interviews, JKR has said that a couple main characters that she hadn't intended dying. Do we have clues as to who this could be?
Possibly.
From Sorcerer's/Philosopher's Stone, we have this little exchange in the Forbidden Forest:
"Yeah," said Hagrid, glancing up, too. "Listen, I'm glad we've run inter yeh, Ronan, 'cause there's a unicorn bin hurt -- you seen anythin'?"
Ronan didn't answer immediately. He stared unblinkingly upward, then sighed again.
"Always the innocent are the first victims," he said. "So it has been for ages past, so it is now."
Now, why is that important to Book 7, you ask? Simple. Cedric's wand had a core of Unicorn hair. And like the Unicorn, Cedric died. Now both Ron and Neville have wands with Unicorn hair cores. Hmmm. One of them, perhaps?
And from other reports, interviews, etc, we also know:
Hermione would see the trio “alive and unscathed and Voldemort finished” in the Mirror of Erised. She may also see herself in a romantic embrace.
This perhaps plays an important role. We all know that the Mirror of Erised shows he person looking at it what they most desire. So, why would Hermione desire to see the trio 'alive and unscathed' if it is so? Is the trio merely greatly traumatized? Or... is it RIP, Ronald Weasley?
Of course, this is all mere speculation, given that I am one of those that look way too far into what's there. But then again, makes you think, doesn't it?
