Questions & Theories: Goblet of Fire

Less than a week away from Deathly Hallows...if you're one of those people who just can't wait, The Guardian is claiming to have the first paragraph of the book, snatched from a screen cap from a forthcoming documentary about JKR that was shot while she was finishing the book. You can view it at Mugglenet if you dare. (In case you're wondering, I didn't. I'm trying to stay spoiler-free.)

* In Harry's vision, Voldemort is telling Peter he's to kill someone. Who is it?

* Is Neville under memory charm to keep him from remembering something about his parents' torture? (This is a popular theory on the Potter sites.) He says the sound from the golden egg "sound like people being tortured." How does he know? They also point to the remembrall turning bright ride in SS - what has he forgotten that is that important?

* Fleur Delacour suggests that the final task may be to find treasure in underground tunnels. Is this, by any chance, the tunnel featured on the U.K. cover?

* Harry's watch breaks during the second task, which Rowling draws attention to more than once. Will he inherit the watch Dumbledore wears and what is its significance?

* Trelawney see Mars at the end of GOF as burning red, similar to Firenze in SS. Is she less of a fraud than we think? (More on this coming under HBP.)

* When Harry is shouting at Cornelius Fudge about what he saw, he names Lucius Malfoy as a Deatheater, and Snape "made a sudden movement." Why?

* What was Dumbledore's "gleam of triumph" when Harry said Voldemort had used his blood? JKR says this is "enormously important." There's something about the blood of sacrifice now being in Voldemort's veins that makes him vulnerable to Harry in a certain way, but I can't put my finger on what it is.
