Dumbledore knows all

Dumbledore enjoyed walking through the quiet corridors of his school. He enjoyed the peace and quiet but he did love a bit of mayhem. The school had been too quiet recently, nothing interesting, by wizarding standard, had happened. He knew all that would change, however, when he heard giggling echoing down the corridor.

Those Weasley twins were at it again. They were in their second year now and they had caused a lot of havoc for their teachers. With a twinkle in his eyes, Dumbledore decided to go and investigate.

When he arrived he found the two boys on opposite sides of the corridor, quietly apologising to the portraits as their wands shed light under their paintings. At least, he found the silhouettes of the boys – their backs were turned to him, crouched in the corridor. On closer inspection, Dumbledore noted that they were using their wands to control a plant they were sticking to the floor. Devil's Snare. How they had come upon the plant, Dumbledore didn't know, nor did he want to find out.

"I take it that this hallway would be unwise to go down tomorrow?" Dumbledore asked casually.

He watched with much amusement as the two boys jumped out of their skins. One let out a very inhuman squeal. Maybe Hagrid should inspect him.

The boys spun around at an impossible speed, even the latest broom couldn't match it.

"Pro- Profe- Professor Dumbledore." One of them stuttered.

"How nice to se- see you." The other added.

"Oh yes," Dumbledore said pleasantly. "I enjoy a calm walk through the corridor after curfew. I see I'm not the only one."

"It's too crowded during the day." One twin stated looking solemn. It seemed that he saw the slight smile on Dumbledore's face, lit by his own wand.

"Can't seem to move." The other agreed.

"I see." Dumbledore said. "And how long will this walk take you? If I was to inspect this hallway in, say, an hour, would your walk be finished?"

"No need to worry professor, we'll be fast asleep by then-"

"-like little angels tucked in our bed." they said.

Dumbledore's smile widened a fraction.

"Enjoy your walk boys." he said as he walked past them, the mirth easily heard in his voice.

Dumbledore walked away from the twins. He didn't plan to check that corridor again but they didn't need to know that.

Dumbledore walked for ten more minutes, moving in the winding corridors of the school when he spotted another light. He thought for a moment it might be Flitwick on his patrol, perhaps he could sway him from colliding with the twins. Instead he noted that the light looked different from that of one created by a wand.

He cast a quick invisibility spell, hiding himself from the light.

Dumbledore walked towards the light quietly and just before he collided with it, he revealed himself. The student in front of him froze like centaur in a bludgers' pathway.

The student was identical to the two boys who Dumbledore had just bumped into. However, this one was holding a muggle device which allowed him to see in the dark. A torch.

"Pro- Professor." The boy stuttered.

"I see you've finished your walk already. I'm guessing your other half is already in bed?" Dumbledore asked.

The boy stood there stuttering and unable to form a sentence, very aware of the muggle device in his hand.

"Goodnight Mr Weasley." Dumbledore said with a wink.

That completely silenced the boy. He stared at the headmaster for a few moments. To the terrified boy, the old man had a smile that just screamed 'I know'.

Jack gave a weak, forced smile.

"Night Professor." he said breathlessly.

Dumbledore walked on with a smile and went about his walk. He listened closely to the noise behind him. After ten seconds, the Weasley twin seemed to be rid of the self-inflicted sticking charm and got his legs working again and stomped quickly in the other direction.

Jack all but ran to the corridor where he knew his brothers were working diligently. He saw them look up as he charged towards them.

"Jackie! You'll nev-"

"Dumbledore knows!" Jack blurted.

"Wait-"

"-what?

"He knows!"

"HOW?" George cried out.

"Didn't you know?" Fred asked, a small smile spreading.

"Dumbledore knows all." Jack answered, his smile also growing.

"And he doesn't care." George finished looking at his brother's smile. Obviously Dumbledore hadn't said anything if Jack was still there.

That night, all four people went to bed with satisfied smiles upon their faces.
