What would happen? (Hogwarts marauders era)

18: The (evil) twins

"Okay," Remus sighed as he crossed his arms, "So," he started summing it up, glaring at each of his friends as he did so.
"And to top it off," Remus' glare deepened, "You just gave me a face full of cream!"

Sirius let a laugh escape, while James just burst out laughing. Peter gave Remus a sorry look as I hid my smile and chuckle behind my hands. Remus had just complained for a full twenty minutes about us as friends. He looked tired, and we could all guess he was sick or something. I knew it was the full moon.

"I'm not joking," Remus said annoyed, "James, focus on your homework!"

James gave Remus a dead look, "Sorry, you want me to listen to you or—"

"Okay," Remus huffed, "Sorry."

"Hm?" I looked up a bit at Remus, "Sorry? You're sorry? While we acted stupid and pranked you?"

Remus uncomfortably picked up his book from the floor and hugged it to his chest a bit. "I've been acting off, I shouldn't have explode like that."

"Oh don't worry about it," Sirius said with a smile, "At least you don't curse my ass."

The other three didn't seem to realise the meaning behind those words, and I had to squeeze my robes a bit.

"I especially liked the insult to James' glasses," Lily walked passed.

James opened his mouth to retort, but at Remus' glare he returned to his homework.

"Personally," Peter said, "I liked the part where he started about (y/n)'s state of her robes."

I adjusted them a bit with a smile before I tried to redo my tie, "That better? I mean, I didn't really care for it on the train here." Sirius went to redo my tie again, showing me that I've been doing it wrong all year. The unnecessary embarrassment almost made my cheeks light up.

"But anyway," Peter said, "Remus, is something up?"

He gave a shrug and turned to his book with a hard look. He was probably lecturing himself, and as I stood with Sirius teaching me how to tie a tie, I couldn't ask him what was up. I wanted to sit next to Remus, to give him a reassuring smile... I couldn't.

"Are you even paying attention?" Sirius asked with a sudden stern frown.

I looked up at him and smiled nervously. "Er, can you redo that..?"

—

Classes immediately stabbed us with homework and what not. Even though we had only been back for a day, already were we studying.

... why would I complain?
It's fucking magic we're learning.

"I can't sit still any longer!" James complained. Me, I just shushed him sternly. We sat in the common room, books open everywhere around us, and the parchments we wrote on spread out on every possible surface. Peter, for instance, used the wall to write his potions essay. He didn't have much other choice or he'd have to sit somewhere else. He said it worked...

"Well you're in luck!" Someone behind James said.

James looked up a bit. "Huh?"

"We,"
"Fabian,"
"And Gideon,"
"Proudly present,"
"A plan to prank everyone—"

"No thanks," Remus grumbled, "Not in the mood, try again later."

James rolled his eyes at Remus, "Boring." Remus glared at James and James now shut up and turned back to his homework. I almost laughed at them.

"Okay..." the prewett twins crossed their arms at the same time before looking at each other, "Prove to us that you don't need our plan."

"I already said," Remus grumbled just as tired as before, "Not in the mood."

"The objective," Fabian said, "Is to prank everyone, using this."

"What's that?" Peter said confused.

Gideon showed a single dung bomb. "Invented in 1800 by Alberic Grunnion, a classic example of a great prank item."

"Only use one, but prank the entirety of the Hogwarts staff with it," Fabian said with a smile, "I bet you can't do them all at once."

"We can," James said confidently but at Remus' glare he said, "Just not today, maybe tomorrow?" Remus hesitantly nodded. "Great, tomorrow, then."

The prewett twins grinned at each other before throwing the bomb at Peter. He caught it clumsily and quickly put it down somewhere safe.

"Okay, we'll just start tomorrow then," I muttered as I pulled my legs up the couch and put the parchment on my knees to write.
My eyes suddenly widened when I realised. "Guys!"

"What?" Sirius asked as he jumped awake a bit.

"You didn't realise, but," I grabbed the dung bomb and went to throw it. A wide variety of no's and what are you doings went through the air as the dung bomb flew through the air. Then it fell on the ground and...

It bounced twice before it rolled underneath one of our chairs. "It's a fake!"

"And you had to test that in the common room!?"

I looked at James, frowning at his yelling, "Well, if it were a fake then the twins wouldn't have just thrown it at Peter either."

"True," Remus shrugged, "I don't know how we'll use a fake dung bomb in a prank though."

James put a hand to his face as he thought. I noticed Sirius turning to his next homework assignment and Remus seemed to fall asleep a bit. I knew the full moon had been three days ago, and I knew Remus probably had a bad one.
I just hoped he was really okay. I still hadn't found a good moment to ask him how he was doing.

"Wait! I know!" Peter suddenly said, "It's a fake!"

"Yeah, we just discovered that," James siad.

"No," Peter shook his head, "I mean, it's a fake, we can pretend to throw it at... at..."

"At the teachers?" I said randomly.

Everyone looked at each other at my words. Would we? Would we not?

"Absolutely not," Remus said, "We'll get detention for months."

"But it'll be fun," Sirius said with a smile, "And I've got to do something to anger my parents anyway."

"Why?" Peter asked with a frown.

"Because I hate them," Sirius explained with a smile, "And I need them to give up on me already. No way am I going to be like them."

"So..." I looked at Remus, "Will we do it?"

Remus stared at his quill for a second. Then he sighed and James jumped up with a, "Yes!"

It was settled.
We were going to make a mess.
