Ah, it seems that the wedding we've been building up to is Bill and Fleur's. It looks like it's a lot fun.
At the wedding, Harry chats with Luna and her dad, and then he goes to talk to a dude named Elphias Doge, Dumbledore's friend. Doge just wrote an article about Dumbledore.
Harry and Doge talk about Rita Skeeter's recent work on Dumbledore. Turns out, it's not just an article she's been cooking up. She's done a book as well.
Ron's Auntie Muriel is listening in on their conversation and chimes in as well.
Through the chat, Harry learns a few things about Dumbledore that he hadn't known before. Auntie Muriel is shocked by how little Harry seems to know about Dumbledore. As is Harry, actually.
Then, Harry and others see a glow in the distance, and a Patronus arrives. Perhaps it's a message of good wishes for the happy couple?
No such luck. The Patronus announces that the ministry has fallen and "they" are coming. We're not exactly sure who "they" are, but probably no one/nothing good.
Sure enough, Death Eaters arrive shortly thereafter, and Hermione, Ron, and Harry Disapparate together to a busy city street.
Hermione, it seems, has prepared for a possible quick departure by packing up a magic bag that's way bigger on the inside than it appears (kind of like a Tardis). That girl really is always three steps ahead, isn't she?
As they walk through the crowded streets of London, she pulls out clothes for them to change into.
