A/N: I finally got my computer fixed! I'm so happy! So now I can continue my story. So, in honor of it being Halloween, and the 30th anniversary of James and Lily's deaths, I must post a Halloween Chapter. I assume it is a great time to give James and Sirius their first round of pranks and trouble-making. Remember, they are only 11 years old so the prank is something that would amuse children around that age. It will be nothing spectacular. Still, I dedicate this Mischief Night/Halloween special chapter to the two people who ensured that All Was Well, James and Lily Potter.

Chapter Three: Halloween

Classes had just ended for the day and the students of Hogwarts were ready to relax. It was Mischief Night, and many of the students were planning mischief of their own. James Potter and Sirius Black were no exception.

"We should do something worthwhile." Sirius said as the two boys walked out into the brisk air of the courtyard. James nodded in agreement, "But what?" The boys were silent as a group of second years passed them. "Something that won't get us expelled?" Sirius mused. "Maybe detention though." James said with a smirk.

"Who's getting detention?"

Remus Lupin appeared behind James, a look of concern on his face. The boys had started to get close over the past few weeks. Remus had even helped Sirius with the History of Magic essay (Sirius had slept through most of Professor Binns' lessons).

James turned to him with his large smile pulling at his lips, "Sirius and I want to do something mischievous tonight!" Remus blinked. James continued, "Nothing too horrible, just something worth doing… to get a laugh, you know?"

"Uh Huh." Remus said lightly, "And who will be the one suffering for your amusement?"

Sirius and James scowled at Remus. Remus crossed his arms across his chest and stared back. "It's not like we're going to hurt anyone, Remus!" James argued, "So don't give me that look!"

"So what are you planning then?" Remus asked. Just as James was about to answer, Peter came up to them smiling happily. "I just finished my tutoring in charms!" He said, "Flitwick says that he's sure I've got it now!" He found a small rock on the ground and pointed his wand at it, "Wingardium Leviosa!"

The rock lifted from the ground, gave a shutter, and fell. Peter chuckled, "Needs a little work."

Remus clapped him on the shoulder, "Good for you Peter!"

"Yeah, very cool." James assured him. He glanced toward Sirius who was obviously not paying attention to Peter. "I have an idea." Sirius said slyly, staring at a group of first-year Gryffindor girls, "But we have to set it up just right."

"Come on Peter." Remus put his arm around the small boy's shoulder, "We don't want to be part of this."

Peter looked at Remus with curiosity, "Part of what?" Sirius and James groaned, giving Remus pleading looks. "We need your help to get the spells just right, Remus!" Sirius said sadly, "I promise we won't tell a soul that you helped!"

Lily lay beneath one of the large trees in the courtyard, staring up into the rustling leaves. Next to her, Elliot and Aida were enthralled by a game of wizards chess that Elliot had brought outside with them. Pyper and Honey were giggling as they compared the cute Hufflepuffs across the way. "Queen to E5." Elliot said, conducting her pieces across the board. Lily heard the crunch of Elliot's queen smashing one of Aida's pieces. "No good!" Aida whimpered, "I'm just not good at this!" She shook her head and leaned back from the board, "I quit. You win." Elliot clapped her hands together, "Undefeated!"

"Can I play?"

Elliot looked up to see Severus standing above them. She smiled at him, "Of course! I'll just have to beat you too!" Aida moved aside so that Severus could sit by the chess board. Looking uncomfortable, she joined Pyper and Honey. Lily sat up against the tree to watch the match.

"No homework to do, Severus?" She asked as the chess pieces moved to their original positions. Seveus shook his head, "No. I finished it earlier. I figured I'd see if you girls were out here…" Lily's face lit up, "See, being in separate houses isn't too bad. We can still see each other."

Elliot looked up from her pieces and groaned, "Don't look now, but here comes trouble." Lily and Severus turned to see Sirius and James walking towards them. Remus and Peter, who were usually right behind them, were nowhere to be seen. "I told you not to look." Elliot said quietly.

"Hey there Evans!" James said happily as he approached. "Go away!" Elliot snapped, "We don't want to hear your stupid voice any more than we have to." James frowned, "Ellie! Don't be so mean! We're bored and—"

"And you wanted to come over here and tease us about hanging out with Severus." Lily barked at him, "It's been a month, James, we've figured you out."

Sirius smiled and bent forward, making eye contact with Lily over the chess board, "You'll need a lot longer than that to figure us out, Lilz." Lily shot him a glare and kicked the chess board up, causing a knight and a rook to hit Sirius in the face. Severus laughed.

"Shut up, Snivvly!" Sirius snapped, glaring at the boy. "To unpopular with the other Slytherins are you? Have to hang out with people from other houses?"

"Girls from other houses?" James chided.

Severus glared.

"At least he's likable enough to have friends." Lily spat.

James scoffed, "Oh yeah, you and Ellie. What a great pair of friends!"

"Watch what you say, Potter." Aida popped in, "They're our friends too!"

James frowned, "Then why don't you girls ever hang out with Snivellus here?" Aida looked from her friends to Severus and back to James. James smiled in triumph, "Because you don't like him either! You put up with him because of Elliot and Lily!" He turned on Elliot, "And YOU only like him because Lily does!"

"You're wrong!" Elliot gasped, "You don't know anything! Just go away!"

James and Sirius laughed.

"Excuse me."

Everyone turned to see a boy in Hufflepuff robes staring at them, a prefect's badge glistening on his chest. "Would there be a problem here?" James smiled sweetly and shook his head, "No sir. Just saying hi and being on our way!"

"See you guys later!" Sirius said, smirking.

They walked off as quick as they had come. "Thanks Dwayne." Elliot said quietly, staring at her older brother. He frowned and sat next to her, "Who are they?" He asked. "Just boys with nothing better to do." Lily said smiling a little at Severus. Dwayne sighed, "I know you don't want to come to me with your problems, Elle, but please… if someone is giving you guys a hard time, tell me… or your own house prefects… or one of the professors… Okay?"

Elliot nodded. Dwayne smiled, "Alright, have a great day you guys."

After he left, Elliot turned back to her game of chess and proceeded to lose horribly to Severus. They, however, never took notice of the boys behind the tree, slipping something into the girl's bags.

"So how will we know if it worked?" James asked Sirius as the prepared to go to bed that night. "Morning. They'll either say something, or wake up the whole dormitory by screaming." Sirius assured him. "It's harmless, so even if they figure out it was us, we'll be okay. Just get some sleep. Good things come to those who wait, you know."

The next morning came about early, filled with the shrieks of the girls who had slept soundly in the Gryffindor dormitories. It was Aida who ran down the stairs first, still clad in her pajamas, pulling a rather large slug from her hair. Honey followed, clearly sobbing as she pulled many different sized slugs from herself. By the time all the girls were free, their whole room was filled with slugs that varied in size, and seemed to be growing...and multiplying at an alarming rate. It didn't take long for Professor McGonagall to arrive. After a quick talk with the girls—who had immiediately blamed James and Sirius—and rounding on the boys, she decided it would be up to Sirius and James to gather all the slugs from the common room (they couldn't go up to the girl's dormitory and clean, much to Elliot's dislike) and then they would help set the slugs free in the forest. They were also to report for detention the next Friday at five o'clock.

Sirius and James conveniently forgot to accuse Peter and Remus as accomplices.

A/N: Okay it's short and it's not that great and I apologize but you need to bare with me through year one. I promise year two will be better. As will year three...and so on. Thank you for your support!
