Yet more Potter

I've just finished re-reading Harry Potter And The Order Of The Phoenix, and I've noticed a few details I missed in my first read. One of the themes is Harry as a leader. This is quite noticeable in a few scenes towards the end of the book:

• Everyone follows Harry to the Ministry of Magic, despite doubts or not being able to perceive their mode of travel. They will follow him, because he is their leader. I think this will have serious echoes in books six and seven. Harry is now a force to be reckoned with in the Wizarding world.
• In the Ministry of Magic, Harry's team line up behind him and draw wands together. Imagine the wedge shaped formation of the Ur-Viles from the Thomas Covenant books. Or, if you haven't read them, imagine that Harry is in front of a triangular formation of his friends. "Wands out!" *Snick*.
• At King's Cross, Harry and Arthur Weasley lead a bunch of Harry's friends over to talk to the Dursleys. Again, the wedge thing, this time Arthur and Harry are leading it.
• Harry leads the Dursleys out of the station.

Of course, there are other clues. I think that the Muggle world and the Wizarding world may need to come closer together, now that there are so many people with a foot in both camps. I also think that Harry and Snape have a closer connection than is previously known. And that Petunia Dursley is not what she seems.

Prediction: Petunia Dursley, nee Evans, like her sister Lily Potter, nee Evans, was also at Hogwarts. she was romantically involved with Severus Snape, but she rejected him and was expelled for some reason. This has lead to Snape's refusal to allow Lily to intercede on his behalf when required, and contributed to his hatred of Potter: his ex-girlfriend's sister has taken up with his tormentor. Meanwhile, Petunia was expelled for doing something very nasty, so she has to live as a Muggle. This explains why she knew instantly what Dementors were and where they guarded, and may explain [SPOILER]'s Howler: "Remember my last, Petunia". Last what? Line of the letter? Condition of not revealing her magical abilities to a husband who would disown her if he found out?

Petunia: "Harry, give me your wand!"

Harry: "Aunt Petunia, you want my what?"

Petunia: "Give me your wand Harry, I need it to do the Unforgivable Curse I was expelled from Hogwarts for."

Harry and Vernon together: "What?! You were at Hogwarts?!"

Petunia: "Malfoy! AVADA KEDAVRA!"

So, when's book six coming out? Next Tuesday, huh?

I'm guessing in less than two years: maybe this time next year, as Rowling's already started writing it. She does have a small baby though, and I know how hard it is to get anything done with an infant in the house.
