anxiously. 

"Dumbledore obviously thinks he might be," said Ron. "It's very lucky he picked tonight, you know," said Hermione as they climbed fully dressed into their sleeping bags and propped themselves on their elbows to talk. "The one night we weren't in the tower...."

" I reckon he's lost track of time, being on the run," said Ron. "Didn't realize it was Halloween. Otherwise he'd have come bursting in here." 

Hermione shuddered. 

All around them, people were asking one another the same question: "How did he get in?" 

"Maybe he knows how to Apparate," said a Ravenclaw a few feet away, "Just appear out of thin air, you know." "

Disguised himself, probably," said a Hufflepuff fifth year. "He could've flown in," suggested Dean Thomas. 

"Honestly, am I the only person who's ever bothered to read Hogwarts, A History?" said Hermione crossly to Harry and Ron. 

"Probably," said Ron. "Why?"

"No," said Amelia.

 "Because the castle's protected by more than walls, You know,,, said Hermione. "There are all sorts of enchantments on it, to stop people entering by stealth. You can't just Apparate in here. And I'd like to see the disguise that could fool those dementors. They're guarding every single entrance to the grounds. They'd have seen him fly in too. And Fitch knows all the secret passages, they'll have them covered...." 

Amelia hummed. "I'm not too sure about all this myself. I have been doing some digging."

"And here we go again," sighed Ron.
