What would happen? (Hogwarts marauders era)

13: Another prank?

"So," Prewett one said as they encountered me in the hallway.

I glanced back at the four boys behind me and smiled nervously. The evening sun shone through the windows as we stood in one of the corridors after dinner.
"When you said two students," James said softly, amazement in his voice, "I never thought it would be them!"

Remus whispered as well, "We shouldn't do this, we've already got detention!"

Sirius said, "Remus is right, let's go! We're on a roll. I'm ready for my next Howler."
("That's not what I meant" Remus muttered confusedly)

Peter said nothing, he just concidered if the trouble was worth it. He decided it wasn't, but it was better than disappointing his new friends.

"Come on," I told Remus, "What's one more detention? Besides, we got away with our first prank."

Patiently the twins waited on us before Remus sighed and very lightly he nodded.

"Okay, we're ready!" I told the twins excitedly as I ran up to them, "What's the plan? I've got one!"

The twins glanced at each other, then they laughed at me.
"What's your plan?" They taunted. "Getting caught?"

I smiled emptily. As I told them my plan, the twins wondered what fucked up brain I had and why on Earth it was that targeted on two people.

"Actually," Gideon said to his brother, "We can do something with this. Just not that bad."

"Yeah, it could be fun," Fabian nodded thoughtfully. Then he looked down at me and smiled, "We'll do it!"

"Do what?" James asked as he had missed out on the whole plan.

Gideon and Fabian explained to them our new plan.

"We will sneak into the Slytherin common room," Gideon said, "(y/n) apparently knows how." I nodded excitedly.

"Then we'll cast a number of spells, which I don't know so we'll use a safer one, which is funnier."

I rolled my eyes. "You're no fun." I wanted to get back at the two stupid Blacks.

Gideon gave me a smile as Fabian continued talking. "Tomorrow morning when the Slytherin students wake up, they'll get a lovely surprise. Of course it will last a day at least before they'll find the counter to the spell."

"Sounds alright," James said thoughtfully, "But what did (y/n) think of?"

I told him softly and James grinned. At least he understood what fun was.

"No," Fabian said frustratedly, "We won't make their robes see through!"

—

When the moon was high up in the sky, we set out to set our plan into motion.
As I read the note someone so conveniently left for me, the wall to the Slytherin common room opened at the word 'mudblood'. I sighed at it as Peter flinched.

"Where'd you get that?" Gideon asked when he noticed how I had gotten the door open. The twins never expected us to get inside, but I proved them wrong.

I pointed to further in the hallway. "Someone's pocket."

Remus glared at me. "Don't steal!"

"Nah," James shook his head, "We hate Slytherins, remember?"
I left out the fact that someone had dropped it.
Because Peeves noticed I was trying to steal it...
Really my plan was bad, I have no defence, it was only because of Peeves that I succeeded.

Fabian sighed and gestured for us to get inside. We found two doors, presumably one to the boys, and one to the girls dormitory.

Gideon told us the spell and how to do it, and with ease me and Peter did it.
"It's not like we're idiots," I told the twins.

"Alright," Fabian tiredly, "You're not idiots."

Sirius winked at me and distracted the twins. I was confused. Did Sirius just wink at me... oh!

Quickly I put a jinx on the door handle to the girls dormitory, putting a charm on it to target it on specific people. It was a trick I had practiced since I had thought of it.

"Let's get going now," James said when I put my wand away again. He grinned at me as we left. Excitedly I jumped out of the common room, only to pause.

Peter bumped into me softly before he squeaked at what he saw in front of me.

"Filch's cat!" He hissed. Sirius and James after us tried to get back to he common room, which Fabian and Gideon closed in front of them with mischievous grins.

"What?" Sirius hit his hand on the wall, "Let us in!"

James gritted his teeth, "Mu... I don't want to say it!"

"Mudblood!" Peter said, but the wall remained closed.

The hissing of a cat had us all quiet.

"How about we run?" Remus suggested softly.

We ran to the nearest stairs.

Once again up in the common room we frustratedly sat down. (Panting and tired, but non of us would admit that part)

"Why did they do that!?" James huffed.

"I never thought I'd ask to get into Slytherin," Sirius said sheepishly.

"Do you think they saw (y/n) cast the charm?" Peter asked softly.

Remus looked at me sharply. "Did you?"

"Did what?" I smiled as I quickly added, "Anyway, it's late, we should head off to bed."

As Remus shook his head at me. I shrugged at him and walked to the girls dormitory.
Once in bed I couldn't stop smiling. I wouldn't trade this for nothing!
