Not long before Hermione was angry with Ron, in the principal's room

"McLean, what do you think this is?" Dumbledore picked the candlestick he put on the table with his wand. At the top of the middle of the three candles, there was a translucent black flame flickering without wind.

Dumbledore took it from Celine's mother's soul with a spell unknown to Marka.

"I don't know. According to what sailin said, this thing should be provoked in manchak swamp..." Maka sat opposite and hesitated. "Maybe it's something related to the voodoo resurrection corpse?"

Dumbledore nodded, but shook his head again.

"Maybe it's related, but I think it should be older." he said slowly, "... Don't get close to the swamp in the United States, at least not at present. We must remember this."

Dumbledore was already "Percy Sirius Black!" Ron said weakly. "In our dormitory! Take a knife! Wake me up!"

There was silence in the common room.

"Nonsense!" Percy looked frightened. "You ate too much, Ron - you had a nightmare --"

"I tell you --"

"Well, that's enough, stop talking!" Professor McGonagall came back again.

When she entered the common room, she slammed the hole in the portrait behind her and looked around angrily.

"I'm glad Gryffindor won the game, but you're ridiculous now! Percy, I expected you to do better!"

"I certainly didn't let them do that, Professor!" Percy tried to look more serious, although he looked a little funny in his pajamas and the badge of the president of the boys' Student Union.

"I'm telling them all to go back to bed! My brother Ron had a nightmare -"

"It's not a nightmare!" Ron shouted hard. "Professor, I wake up and Sirius Black is standing in front of me with a knife!"

Professor McGonagall stared at him.

"Don't make people laugh, Weasley. How can he get through the hole in the portrait?"

"Ask him!" Ron pointed tremblingly at the back of Sir cardogan's portrait. "Ask him if he saw --"

Professor McGonagall glanced suspiciously at Ron, pushed the picture away and went out by himself.

The whole common room held its breath.

"Sir cardogan, did you just let a man into the Gryffindor tower?"

"Of course, madam!" cried Sir cardogan.

Everyone was speechless with surprise, both inside and outside the public lounge.

"Did you -- did you do that?" Professor McGonagall asked in surprise. "But -- but what about the password!"

"He has a password!" said Sir cardogan proudly. "A password for the whole week, madam! Read it on a small piece of paper!"

Professor McGonagall came back from the hole in the portrait. In the face of these surprised students, she looked like chalk.

"Which one," her voice trembled and looked a little incredible, "which completely ignorant fool wrote down all the passwords for this week and left them everywhere?"

There was silence, and then a tiny, frightened voice broke the silence.

Neville Longbottom trembled from his feet in fluffy slippers to the tip of his hair. He slowly raised his hand.
