Not pausing to think, James did the first thing that came to his mind. He whispered, "Accio Cloak," and watched as his invisibility cloak flew from across the room and settled over the four boys, hiding them and the cauldron, from view. Suddenly, the classroom door flew open and light flooded into the dark room. There in the doorway stood Lily Evans, Peeves the school poltergeist close behind her. Lily's emerald green eyes scanned the room, then rounded on Peeves. "This isn't funny, Peeves. You wasted my time by making me come here, when I could be catching up on my Potions homework." Lily glared at Peeves, who just floated there, dumbfounded. "But I could have sworn..." He started, but Lily cut him off. "That's nice, Peeves, but I must go now. Goodbye and good night." She turned and walked away, flipping her dark red hair over her shoulder before disappearing around a corner. Not long after, Peeves glided away, most likely to cause some mischief.

James let out a sigh of relief, before pulling the cloak off of them. The four boys begin to clean up in silence, all still in shock from such a close encounter. James and Sirius stored the cauldron inside a large cupboard, while Remus and Peter gathered all of the potion ingredients. Finally, they were ready to head back to the Gryffindor Common Room.

------------------------

They got back to the common room with out any incidents. As soon as they entered the room, James and Sirius flopped down onto a nearby couch, exhausted from the day's work. Remus sat down in a large armchair, while Peter settled himself on the floor.

Remus looked around at his friends. "We need nicknames. Something we can call each other so that no one knows who we are talking about." Sirius glanced at James, a grin on his face. "Well, James already has a nickname. You know - Jamsie." James glared at Sirius, but didn't bother to respond. "How about nicknames relating to our Animagi forms." He paused, shooting an apologetic look at Remus, "And Remus can have a name that relates to a werewolf." Remus stared into the fire, deep in thought. "Werewolf... full moon... moon... I know, how about Moony?" James nodded. "Great, now how about me? Stag... Antlers? No..." Peter looked up at him, his eyes bright. "Prongs." He whispered. Sirius and Remus stared at him, surprised. James looked thoughtful. "Nice name, Peter. Alright, I'm Prongs. Now we need one for Peter." Peter rested his head on his hands. "Rats have long tails... hairless tails, like worms... Wormtail!" Peter looked up, surprised at his own cleverness. Sirius clapped softly, then fell into his own thoughts, thinking of a name. "Dog, black dog. Big dog... paws... padded paws..." James coughed and mumbled something that sounded a lot like 'Paddy'. Sirius glared at James, then continued. "Paddy feet, Pad feet, Pad foot... Yeah, that's it, Padfoot." Sirius grinned at the rest of them, glad that they all had nicknames.

Remus looked at each of his friends individually, saying their name when he looked at them. "Padfoot, Prongs, Wormtail. It'll take us awhile to keep saying Moony, Wormtail, Padfoot, and Prongs, so I was thinking we could call ourselves something. Something like... the Marauders. It means mischief." He explained, seeing their confused looks. The four boys grinned at each other, happy that things had gone so well that day.

The silence was broken when James hit his forehead with his hand and muttered various swear words under his breath. "Guys, I... I left my invisibility cloak back in the classroom." The three other Marauders turned to look at him. Sirius was the first to speak. "Well, Prongs, my friend, I guess we'll just have to go and get it. It's no big deal." Moony, who was usually calm and composed, was fidgeting in his chair. "I don't know, Padfoot, something doesn't feel right." Sirius stood up, along with James, who was following his lead. Peter, who was watching them with wide eyes at the thought of sneaking out once more, hesitated, but stood up all the same. Finally, Remus stood up as well. The Marauders pushed open the portrait hole and stepped out into the deserted corridor.

------------------------

The four boys walked out of the classroom, cloak in hand. A movement to their left caught their attention. "What the-" Sirius started as a shadowy figure started to sprint down the corridor away from them. They managed to glimpse the figure's dark, greasy hair and dirty robes with the Slytherin House emblem on the chest. James pulled out his wand and saw Sirius and Remus do the same. James looked at his friends, his expression a mixture of anger and disgust. "Snivellus." He said, breaking into a run.
