DH29: The Lost Diadem – Harry Potter Lexicon

"Everyone in this Room's been fighting and they're been driven in here because the Carrows were hunting them down. Everyone in here's proven they're loyal to Dumbledore - loyal to you."
-- Neville Longbottom

Neville Longbottom escorts Harry, Ron and Hermione through the passageway from the Hog’s Head to the Room of Requirement, where Dumbledore’s Army recaps the situation in Hogwarts and the Ravenclaws tell Harry about Ravenclaw’s diadem. Luna Lovegood escorts Harry to the Ravenclaw Tower to look at its representation on Rowena Ravenclaw’s statue, and Alecto Carrow ambushes them in the Ravenclaw common room.

Calendar and Dates

Immediately after the preceding chapter, on the same May evening in 1998.

Interesting facts and notes

Apparating directly into the bar

Presumably - since nobody can Apparate into or out of Hogwarts without the headmaster's cooperation, such as during Apparition lessons in the Great Hall - this refers to the members of Dumbledore's Army who turn up later from outside the school. But in the last chapter, we just established that the Death Eaters have anti-Apparition spells up, so that the trio would have had to wait until the Caterwauling Charm was lifted in the morning to walk out of Hogsmeade into the mountains, to get clear of the spell. This seems to be a contradiction.

We're up on the fifth floor

Hmm. Let's see if we can get some idea of where the entrance to Ravenclaw Tower is then.

By the way, the Room of Requirement is ordinarily found on the seventh floor.

I was wondering whether Filch, as a Squib, would have been kept on by the Death Eaters, no matter how much he loves corporal punishment of the students.

They climbed in tight, dizzying circles.

Since they started on the fifth floor, the entrance to Ravenclaw Tower is at least on the sixth floor.

Ravenclaw's symbol.

Not the lake or the forest, in other words. This is consistent with Ravenclaw Tower being on the opposite side of the castle from Gryffindor Tower.

It was not unlike the tiara Fleur had worn at her wedding.

Nice red herring, that.

'Wit beyond measure is man's greatest treasure.'

Luna quoted this during her first conversation with Harry (OP10).

Memorable lines

"Look after 'em, then," said Aberforth gruffly. "I might not be able to save 'em a third time."

"Blimey, Neville," said Ron, "there's a time and a place for getting a smart mouth."

"Little old witch living alone, they probably thought they didn't need to send anyone particularly powerful. Anyway," Neville laughed, "Dawlish is still in St. Mungo's and Gran's on the run."
