The Sorcerer's Stone (Percy Jackson and Harry Potter crossover)

Merry Christmas, here's your Detention

Disclaimer... I do not own Percy Jackson or Harry Potter. They belong to Rick Riordan and J.K. Rowling. I am so excited about this chapter and the next one. On with the Story!

Weekend turned in and the Trio decided to go to Hagrid's, to meet up and also to do a little investigation.

"He's a goody two shoes, he'll babble on us." Ron said.

"He's my friend and he should know about this." Harry said.

"He's a human being and he can speak for himself." Percy said.

"I agree with Percy." Hermione nodded.

Then the realisation dawned on them as they jumped and looked at Percy.

"Honestly guys, you need to learn about constant vigilance. It's trending. As for letting me in o your little secret," he glared at Ron, "I have no interest. Just don't do anything stupid and you have my blessing."

With that good news, he stepped out of the portrait hole to go to the Black Lake.

But he never reached there. Because he fell victim of a truly dreadful thing.

"Percy!" Fred came to him.

"What happened?" Percy was startled.

"Professor Snape is calling you!" Fred said.

"Me? Why?" Percy was now confused.

"Dunno mate. You should hurry." Fred pushed him along.

In his hurry, he did not notice the change in his clothes. It was only seconds before knocking on the door that he noticed the change.

He was fricking Santa Claus.

"No harm done. Just walk back out." He told himself and moved backwards. Then his back collided with a professor. More specifically, professor Snape.

His breath hitchhiked. And that's when the song started...We Wish You a Merry Christmas. Sprinklers of confetti burst in, raining down on them. And in the middle of the celebration was a trembling Santa Claus and a glaring Krampus.

"I...I can explain." Percy gulped as he turned around towards him.

"It seems you are too excited for this festival Mr. Jackson," Snape said, "Did you plan a surprise in my class? We should check it out."

"No." Percy covered his face as Snape opened the door. The whole classroom was covered in gift wrapping paper. And on the wall was a big banner saying 'The Merriest of Christmas Professor Snape. From Percy Jackson.'

Snape blinked twice at the sight before looking back at Percy.

"Weekend," Snape began, "is cancelled for you. Today you will clean this up, without magic. And tomorrow, you will have a full day Potions class with me. one wrong potion will result in one more day of detention and ten points off Gryffindor. Also, twenty points off Gryffindor right now. Come at 12o' clock and you will be dismissed ten minutes before dinner. Off you go." Snape entered the class and banged the door shut behind him.

The song changed to 'Joy to the World' and Percy groaned.

As he walked back in the Common Room, he saw the Trio on the couch, about to leave. Opposite to them were the twins, grinning at him.

"Ho, Ho, Ho." Fred said.

"Where's our present?" George asked.

"There it is." They both pointed at Percy and laughed. Percy cocked his head and gave them his trademark troublemaker smirk.

"Uh oh," Harry stood up, "Percy, whatever you are thinking, I strictly advise against it."

"Oh no Harry dear, I am going for it," Percy pointed at the twins, "You have just begun a prank war."

"We are the troublemaker duo of this school. What has a first year against us?" George asked.

"You are the troublemaker duo, I am the King. Bring it on." He walked up to his room.

"What s got you so pale?" Hermione asked Harry.

"I have a bad feeling about dinner tonight." Harry said.

"Let's just go." Ron said.

Percy spent the rest of the day in Snape's classroom, forming a very devious plan.

What do you think our little evil Percy has got planned for the twins. It is going to be amaZhang if Percy is involved in this. You just gotta wait for it. Till then.

Raven.
