Saturday arrived quickly. Too quickly, in fact, for Andi, who was nervous about her part in the Great Prank of '89, as Fred had dubbed their plan.

At six o'clock, they were going over last-minute changes to the plan. Butterflies were dancing around in Andi's stomach.

"I still say rocks won't be enough. Don't we have any dungbombs?" asked George.

"Yeah, a couple, but I'd rather save them for later," said Fred.

"Use them now," said Andi. "If we're going to get detention for the rest of the year, we could at least go out with a very large bang."

"True. I'll grab them," said Fred, rummaging through a trunk. They were gathered in the boys' dormitory. Everyone else was at dinner, so the Gryffindor Tower was deserted.

At 6:50, Fred and George loaded Andi up with last-minute advice and dungbombs to set off. She had found a convenient suit of armor outside of Filch's office the day before. She jogged off and hid behind it. Several minutes later, Fred and George ambled into Filch's office. Fred lagged a bit and winked at her, signaling that the prank was about to begin.

After nearly 20 minutes (during which she assumed Fred and George were filing and secretly looking for a key to the drawer) Andi snuck out several feet down the corridor, set the dungbombs off, tossed them into the air, and let out a piercing shriek. It was a good thing she was a natural actress.

Filch ran into the hall. He immediately caused the source of the commotion: a small first-year girl, huddled in a ball with dungbombs all around her. He hobbled over to her. She was crying and shaking.

"Who?" he grunted, not one to waste time. Andi sniffed and took a breath.

"Peeves. He-he set off the dungbombs on me, he's horrible," she wailed, trying not to laugh with all her might.

"You go to the Hospital Wing and get cleaned up," he said gruffly. "I'll find Peeves and deal with him."

And with that, Filch stormed off, turning into corridors randomly. Once he was out of sight and earshot, Andi jumped to her feet and darted into his office, aware each precious second ticking by.

"The key won't work, Andi," said Fred, who was attempting to jam it into the lock. "None of them will."

"Fine-let me see-" Andi tried each key on the ring. None worked. "Alohamora!" She tapped the drawer with her wand. It obediently slid open, revealing a treasure trove of objects.

"Take a bunch," George instructed. "We'll sort through the stuff later, here-" Andi stuffed her robes pockets full and looked around.

"Have a good detention, don't get in more trouble," Andi said, locking the drawer again. "Act normal, above all else." She ran to the Gryffindor Tower, dumped the stuff under Fred's bed in the boys' dorm-which was still empty-and made her way to the Hospital Wing. That place was becoming extremely familiar to Andi.

"Madam Pomfrey?" she called, letting a slight quiver enter her voice.

"Yes, Andi, dear?" Madam Pomfrey now recognized Andi on sight.

"Peeves dropped dungbombs on me, and Mr. Filch told me to go to you to get cleaned up," Andi explained.

"Oh, dear. Right this way, then." Madam Pomfrey led Andi to a small bathroom with a shower and gave her a towel. "There will be fresh robes waiting right here when you're done," she said, closing the door behind her.

Andi scrubbed herself furiously in the shower, trying to get the disgusting stench off her skin and out of her hair. When she was satisfied, she dried herself off and pulled on the clean, dry robes that Madam Pomfrey had provided. With a quick spell, she dried her hair and then pulled on her shoes.

"Thank you, Madam Pomfrey," she said on her way out. "If Mr. Filch stops by, do tell him that I'm fine."

"I will, dear. Have a good night now," the nurse said fondly as Andi exited the Hospital Wing.

When she got back to the dorm, Fred and George weren't quite back yet. Lee was, though. He raised his eyebrows.

"What happened to you?" he asked. "Filch came through looking for you earlier."

"You'll find out from Fred and George eventually, I guess. I helped them with a prank, which involved me setting off dungbombs on myself and blaming Peeves."

"Dude," Lee said. "That is so awesome! Why, though?"

"I'll explain that when they get back. It was worth it, though."


Soon, Fred and George were back. They had numerous paper cuts on their fingers from all the filing they had done.

"So, what'd we get?" George asked eagerly.

"Haven't looked through it yet. Lee wants to know about it, though," Andi said.

"Oh. Hi, Lee," said Fred.

"It's under your bed, Fred," said Andi.

"I'm George," Fred said.

"No you're not." Andi, somehow, was beginning to be able to tell them apart.

"Fine, you win," said Fred, running up the stairs. He returned with his robes pockets and hands full. He spread the items out on the table.

"How are love potions highly dangerous?" Andi wondered, looking at the small bottle. "And lollipops?"

"Don't eat that!" George warned quickly before she could open it.

"That's an Acid Pop. It'll burn right through your tongue," said Fred, eyes wide.

"Our little brother Ron tried to eat one once."

"We gave it to him, remember George?"

"Oh right…we did, didn't we?"

"It was mainly you."

"Yeah, but you turned his teddy bear into a giant spider."

"He broke my toy broomstick!" protested Fred. Andi and Lee were watching with amusement.

"That's still right mean of you," Andi pointed out.

"It wasn't on purpose, it was accidental magic," said George calmly. "Happens a lot in our family."

"Let's get back to the stuff, shall we?" said Fred. "There are like twenty dungbombs here, excellent."

In the end, they came up with:

1 love potion

17 dungbombs

3 Acid Pops

2 containers of Bertie Bott's Every Flavor Beans

8 Cockroach Clusters

1 blank piece of parchment

And about a dozen other random items, including Fanged Frisbees, Fizzing Whizbees, and even a punching telescope.

Andi examined the blank parchment. "I wonder why this's here?"

"Me, too. Maybe it's got invisible ink or something," George said, looking at it over her shoulder.

"Hang on, I think I know what to do," Fred said. "I saw Dad do this once. Reveal your secrets!" he exclaimed, putting the tip of his wand on the parchment. To Andi's surprise, black ink blossomed across the paper:

Mr. Moony thinks that the Marauders shall definitely not reveal their secrets to insolent first-years.

Mr. Padfoot notes that the first-years are not taking their studies siriusly.

Mr. Wormtail suggests they quit pranks and focus on homework.

Mr. Prongs would like to correct Mr. Padfoot's spelling and mention that he does not know how these silly first-years got into Gryffindor.

Andi burst out laughing, as did Lee. The twins glared at the parchment.

"Andi requests that you reveal your secrets on behalf of the Weasley twins," Andi tried.

Mr. Wormtail wonders why such an eloquent, well-mannered person is friends with the Weasley twins.

Mr. Padfoot wonders how the Weasley twins made it to Gryffindor if they are letting a girl do their work for them and possibly boss them around.

Mr. Moony agrees with above statements and adds that Miss Andi should focus on her homework.

Mr. Prongs requests that the Weasley Twins keep their abnormally freckled faces out of other peoples' business.

"Hey!" protested Fred. "C'mon, we're not letting her boss us around!" Andi raised her eyebrows.

Mr. Prongs wonders why the Weasley twins are so disagreeable, and has decided to retire for the night.

Mr. Wormtail seconds this.

Mr. Moony bids the Weasley twins and Miss Andi good night.

Mr. Padfoot agrees with all the above statements.

"Well, good night then, Misters Moony, Wormtail, Padfoot, and Prongs," Andi said, setting it back on the table.

Mr. Prongs wonders why Miss Andi is being so polite.

Mr. Moony seconds this notion.

Mr. Padfoot wonders why they are giving up so easily.

Mr. Wormtail adds that Miss Andi and her companions must be abnormally tired to give up like this.

"We're tired because we pulled a tricky prank on Filch," George explained.

Prank? The parchment flickered. Do tell.

"Yes, prank. Anything to say about it?" asked Andi.

Mr. Padfoot makes a motion that the Marauders may have been a bit hasty in their evaluation of the Weasley twins and Miss Andi.

Mr. Wormtail inquires more about this prank on Filch.

Mr. Moony rolls his eyes at the eternal hopelessness of his companions.

Mr. Prongs ignores Mr. Moony and thinks that the Weasley twins may be worthy yet.

"Well, Filch has a drawer in his office marked 'Confiscated and Highly Dangerous," Fred started.

"We decided to break into it, and so-" continued George.

"We got ourselves in detention-"

"And with the competent acting help of Andi-"

"Managed to distract him-"

"And make off with several items from this drawer-"

"Including this piece of parchment," Fred finished.

Mr. Moony wonders what part Miss Andi played in this small prank.

"I wasn't in detention, so I distracted Filch by setting off dungbombs on myself and pretending Peeves did it."

Mr. Padfoot congratulates Miss Andi on her guts to attempt such a feat, and her aptitude in getting away with it.

Mr. Prongs agrees, and compliments Miss Andi on her everlasting awesomeness. (Mr. Prongs also wonders where Mr. Padfoot learned the word 'aptitude.')

Mr. Wormtail wonders why his companions are-

Mr. Moony requests that Mr. Wormtail shuts up before he gets us all in trouble.

Mr. Wormtail reluctantly agrees.

"Andi thanks Misters Padfoot, Prongs, and Moony. So what's this parchment for, and how do we get to it?" Andi asked.

Mr. Moony decides that the Weasley twins and Miss Andi will find out when they guess the password.

Mr. Wormtail suggests that they promise to use it for mischief-making.

Mr. Prongs suggests they make it official-sounding.

Mr. Padfoot suggests they make it first-person.

"Umm…so, I sincerely promise that I am going to make mischief?" Andi tried.

Mr. Prongs repeats his advice and adds that a promise isn't really official.

"I swear that I am going to make mischief?"

Mr. Wormtail notes that his wording didn't really matter.

"I swear that I am…going to make trouble?" George said after a minute.

Mr. Padfoot suggests that they keep trying, and add something to make it sincere.

"I sincerely swear that I am going to make trouble?" Fred tried.

Mr. Padfoot suggests finding synonyms for sincerely and going to make trouble.

"Up to no good?" Andi suggested.

"That's a good one, pun not intended, I sincerely swear that I am up to no good?" asked Fred.

Mr. Moony smirks at how close and yet how far the Weasley twins and Miss Andi are from the password.

"Andi would like to inquire if Mr. Moony could tell us how many words we are messing up," Andi said.

Mr. Moony could, and maybe Mr. Moony shall.

"How many?" George asked.

Mr. Moony suggests you try to solve an equation, and prohibits Miss Andi from helping for at least two minutes. [(5q3 – 7 + 3x) (6t + q2 – 4x3)]0

"Andi, what's the answer?" asked George, staring at the polynomials.

"Mmmph!" Andi exclaimed. She couldn't talk. She supposed that was part of Mr. Moony's magic.

"How do you solve this?" wondered Fred, turning the parchment upside down in an effort to understand it. "It's impossible!"

Andi rolled her eyes and shook her head. It was an easy equation, really; her class had learned the theory behind it in 6th grade.

Finally, two minutes were up. Andi glanced at the equation once more for confirmation and stated her answer. "One."

"What? What happens to the little letters?" asked George.

"The zero on the outside, it makes the answer one because there are none of the terms inside the brackets."

"How?" asked Fred, looking confused.

"Never mind, it just does. Let's focus on the password. We must have sincerely wrong, Mr. Padfoot told us to find a synonym."

Mr. Moony congratulates Miss Andi on her muggle-born algebra and deduction skills.

"Thank you, Mr. Moony," said Andi. "Sincerely…maybe earnestly?"

"I earnestly swear that I am up to no good?" Fred asked. "Doesn't sound right." It didn't work, either.

"Seriously?" Andi said thoughtfully. "I seriously swear that I am up to no good."

Mr. Padfoot makes a motion that Miss Andi is hilarious, and that if they got the joke, the Weasley twins would find it funny as well.

Mr. Prongs notes that this wordplay joke is funny, but it got old after first year.

Mr. Wormtail thinks that this is a silly argument.

Mr. Moony rolls his eyes at Mr. Padfoot, and suggests that Miss Andi not use the word 'seriously' or any of its derivatives around Mr. Padfoot until he becomes more mature than a seven-year-old.

Andi snorted, though she couldn't see why the word seriously was so funny. "Okay, solemnly then? I solemnly swear that I am up to no good!"

Messrs. Moony, Wormtail, Padfoot, and Prongs are proud to present…The Marauders' Map

"The Marauders' Map?" asked George. "What's it do?"

"Watch," Andi said. Little trails of ink were spreading across the parchment, which was also unfolding of its own accord. "It's a map of Hogwarts!" she decided, seeing the words 'Great Hall' etch themselves into an open space.

"Hold on," said Fred. "That's us!" He pointed to a group of three (Lee had gone to bed) labels. Overlapping were the words 'Andromeda Kirkwood,' 'George Weasley,' and 'Frederick Weasley.'

"Brilliant! It shows everyone and where they are!" Andi yelped, scanning the parchment. Dumbledore was pacing in his office. Peeves was flying around a corridor filled with students, no doubt causing trouble.

After a while, they tired of this and decided to go to bed. "Wait, how do we close it? If a teacher finds it like this, we're in trouble."

"Maybe another password?" suggested George. "It'll have to do with a prank or something, I bet."

"Right. Maybe 'Trouble-making accomplished?'" The map did nothing at Andi's words.

"Prank completed?" asked Fred.

"Mischief Managed!" exclaimed George. The map turned into a blank parchment again.

"Good job, George," said Andi. "Let's go to bed, it's late."

"But, we don't have classes in the morning!" protested Fred.

"Still, I'm tired," Andi yawned. "I'll stay up late another time, but right now I'm going to bed." Andi walked down the boys' stairs, up the girls', and into the dorm. Everyone else was already asleep; Andi immediately closed her eyes and fell into a deep sleep, exhausted.


Thunk. Bang. Andi woke to strange noises coming from the stairwell. It was still fairly early. She got up, dressed, and opened the door in time to see quite a strange sight.

Fred and George were attempting to outrun the staircase, with not-so-great results. They weren't making it two yards before sliding back down each time. Fred looked up and spotted her.

"Andi! Finally! You're up! I thought we'd never get up the stairs," he nearly yelled.

"And you never will. They're enchanted," Andi said, watching the stairs warily. "Back off a bit, I want to come down without sliding."

Fred and George backed up a few feet. Andi walked down calmly. Right as she stepped off, the twins hooked their arms around hers, turned around, and started to drag her backwards towards the portrait hole.

"Ouch! Get off!" yelped Andi. She tried to stay on her feet. It wasn't working; the twins were taller than her and there were two of them. "Fred! George! Off!"

"No can do, Andromeda, friend," said Fred happily.

"We've been summoned to Dumbledore's office," George said, equally gleefully. "Hey, Fred, what was the name of that one muggle movie Mum took us to once?"

"I dunno, something about Kansas and Toto?" Fred frowned. It clicked into Andi's mind immediately.

"The Wonderful Wizard of Oz?" she said, somewhat confused.

"Right! On three, George?" Fred asked.

"One, two, three!" George said.

"We're off to see the wizard, the wonderful wizard of Oz. He surely is a wonderful wiz if ever a wiz there was!" they chorused.

"Oh my gosh, you two. Why are we going to see Dumbledore?"

"I don't know, maybe the dungbomb incident?" suggested Fred with an evil glint in his eye. "Anyways, let's go again, George. One, two, three!"

"We're off to see the wizard, the wonderful wizard of Oz. He surely is a wonderful wiz if ever a wiz there was!" they sang at the top of their lungs. Andi tried to look like she didn't know the two singing lunatics as teachers stared at the trio.

Fred and George sang and dragged Andi all the way into Dumbledore's office.

"Do let Miss Kirkwood go, Misters Weasley. I'm sure she loves hearing about the Wonderful Wizard of Oz, but there is a limit to how much fun you can have at one time."

Fred and George immediately dropped Andi, who flailed her arms, fell down, and scrambled back to her feet.

"Thank you, Professor," she said, slightly out of breath.

"Quite welcome, Andi. Lemon drop, anyone? No? Okay, then. Do you know why you're here?"

"Not a clue," said Fred.

"Nope," clarified George.

"We're done nothing wrong."

"As far as we know, that is."

"So why?" they said together.

"Mr. Filch has reported a strange incident. It seems that when you two were in detention, and he had to leave for a disturbing incident involving Peeves and Miss Kirkwood-" Andi struggled to avoid turning bright red. "-someone or something took several confiscated and dangerous items from a locked drawer."

"Really?" George asked, beaming.

"That's brilliant!" Fred exclaimed.

"Whoever did it," George started.

"Must have snuck right past us!" finished Fred.

"D'you know who did it?" they both asked. Dumbledore chuckled.

"No, I'm afraid we don't. This has answered my questions, it seems that you don't know either. Back to your dorm, now. We can't have you missing breakfast; it is, after all, the most important meal of the day."

Andi exhaled as they walked through the hallway. Fred and George hadn't decided to drag her backwards this time.

A/N: So, who wants to know what Wormtail was about to say when Moony cut him off? Review, and you shall be told ;)
