Note shared between Sirius and James during Potions on October 30th:
J: So what are we going to do tonight?
S: Um, sleep…
J: NO! I mean for Mischief Night!
S: What?
J: It's a muggle thing.
S: That's exactly why no one cares.
J: Keep your pants on! I wasn't done. it's the night before Halloween where you go out and make trouble. Muggles usually do stupid stuff like teepee things but since we're wizards, we can do just about anything.
S: I'm liking where this is going…
J: So am I. We'll consult with Remus at lunch.
Consulting with Remus over lunch:
"You guys are a bunch of idiots," said Remus with a smirk. "Pass the potatoes. I'm not in on another one of your half-baked schemes!"
"HALF-BAKED? Are you accusing me of being my mother's meatloaf?" James said, infuriated. "I'll have none of that! I hate meatloaf. When have I ever come up with a Meatloaf Scheme?"
"Um," said Sirius looking sheepish at countering James. "Remember when we were trying to find out the measurements of Professor's Sylvie and you almost got into the second detention of the day? That was semi-half-baked…"
"SEMI? SEMI? Of all the betrayal. And you're my best mate! And it was you that said we needed the measurements!" James protested.
"WOULD YOU pass the freakin' potatoes?" Remus said loudly. All the Gryffindors looked over and sniggered. He turned red as he took the potatoes from a smirking Sirius. Once they had all continued eating Remus said, "I suppose it wouldn't be THAT bad to do some trouble-making. But could we get Stephen Gillman? He called me a scrawny whelp and punched me when I didn't give him my homework for him to copy."
James grinned. "Oh, we're gonna get a few Slytherins. In fact, I'm thinkin we should focus on finding their entire house for our map. I mean we already have Hufflepuff and Ravenclaw from following Regina Richards and Tommy Poppert."
Sirius laughed. "Poppert. I love that name…"
James's Notebook. Written during Charms:
Operation: Mischief Night
Preparation: Have Pettigrew follow Stephen Gillman. DON'T TELL HIM WHY!
Sirius: Code name- Flamingo Mission: Distraction of Slytherins to vacate the Common Room/ Keep Watch (Sleeping Charm)
James: Code name- Tango Mission: Cast booby trap spells
Remus: Code name- Waltz Mission: Cast booby trap spells
Operation: Mischief Night. Midnight in the Gryffindor Common Room:
"I still don't understand why I always have to keep watch. Like a dog or something!" said Sirius, annoyed. (A/N hah… that's totally ironic)
"Aww… stop complaining! Buck up, BUCKO!" said James.
"Jeez, James… must you be such a bloody dweeb?" This was Sirius.
"Hey! Don't forget the code names!"
"Alright," Remus intervened before Sirius could strangle James. "Let's go."
When they arrived at the Slytherin House, they poked their head through the door. There was just one person still there. Sirius had already left the poisoned cupcakes from "Professor Sylvie" the House Leader. Slytherins were gullible and basked in their own glory way too much. (This was at least James, Sirius, and Remus's opinions along with the entire Gryffindor House)
Sirius moodily kept watch while James and Remus did a few little tricks with slime blasting out of their wands every once and a while. Remus almost had his attacking thumbtacks attack James which amused Sirius. When they were finished, they started up the steps. The Slytherin Common Room was down in a dungeon and 2 flights separated them from the First Floor.
They were creeping about the Seventh Floor coming vaguely closer to Gryffindor which was unluckily in a TOWER. They were panting quite excessively when they heard it: a meow.
"Oh… poopy," said James. "It's Mrs. Norris. Filch will be around anytime now. We need to hide."
They sprinted, all thinking, "OH, MY GOD! WE NEED A PLACE TO HIDE!"
Remus skidded to a halt and pointed to a door. They went in and found themselves in perfect madhouse with confusing mirrors, doors and such. "Oddest thing.." said Sirius. "This is the perfect place to hide."
Once the coast was clear they sprinted back to the dorms and dreamed of that peculiar madhouse.
A/N: If you know, don't say… :P
