But until then, my predictions.
The end of the story will be something about Harry meeting his mother and knowing her embrace. Either he will die and finally meet her, or, he will be granted some sort of other-worldly experience where he is able to make the physical connection.
Harry’s family has a link to Godric Gryffindor, which he begins to piece together when he visits the place of his birth, Godric’s Hollow.
Snape redeems himself. Dumbledore believed in him, and so do I.
Neither Ron nor Hermione will die.
At least one, and maybe both “major” deaths will occur at in an attempt to save Harry or one of his friends and will account for some sort of redemption for the victim. My vote for the One Most Likely To Be A Goner in Book 7 is Snape. I’m going with the Sidney Carton theme here. I’m also thinking that the story will be something along the lines of Snape dying and THEN Harry understanding Snape’s true nature and why Albus trusted him, etc.
Others on the redemption wagon are Peter Pettigrew (he has a life debt to Harry, so this seems obvious) and Neville (my favorite… who I really, really, really want to remain safe.)
I don’t think Harry will be the one to do Voldemort in… maybe I’m harping on the same theme here, but Snape is a top contender for finishing him off in my mind.
Dumbledore continues to mentor Harry from beyond. The pensieve (over the Star Wars glowing Yoda) is my guess for how.
RAB is Sirirus’s brother. It’ll be a good pick-me-up for Harry to discover that another of the Black family line turned ‘good’ in the end. Kreacher will be involved in figuring out this plot line.
I’m struggling with a ‘Harry is a horcrux idea’. I keep thinking about Dumbledore’s eyes lighting up at the news that Voldemort used Harry’s blood in Book 4 — did Voldemort tap into Harry’s horcrux-qualities when he did this? There is more to the story of Harry’s scar and his parents’ involvement.
Percy has a breakdown, becomes fun, and settles down with Madam Rosmerta. (One can hope!)
