A/N: As always, J.K. Rowling owns the Potterverse. I just enjoy messing with some of the things she's left in this particular sandbox.

Daphne Greengrass was a self-admitted perfectionist. She expected her work to be perfect, her clothes to be perfect, her meals to be perfect, and most importantly of all, she expected her bed to be made perfectly. It was a job she trusted to no one but herself. So when she came back from classes to see that her bed was no longer perfectly made, she had to restrain her impulse to scream while she examined the mess that had been left behind. Remaking the bed while she thought would help, she hoped.

She knew no house elf would have done this; she had long ago warned them off of touching her bed. The boys of Slytherin were forbidden from entering the rooms of the girls, and since that promise was enforced by magic as similar standards had been enforced throughout every House in Hogwarts, none of them would have been able to get in either. So that left only the other girls in Slytherin (as Daphne immediately dismissed the notion that any girl from another House would willingly enter the Snakes' common room).

Most of the younger years knew better than to try and raise Daphne's ire (her sister Astoria notwithstanding), so for any of them to have done this seemed extremely unlikely. The older Slytherins couldn't be bothered to interact with those below them, so they could also be safely ruled out. Which left Daphne with just three suspects: her roommates Tracy, Pansy, and Millicent.

Tracy was Daphne's closest and best friend. While she sometimes had an odd sense of humor, she also knew Daphne's perfectionism was her bastion of calm in an often insane world, and would never use that to play a joke on her friend. And then there were two.

Millicent, while being large for her age, was a very gentle giant unless provoked to take action. Not being an utter fool (or worse, thought Daphne, a Gryffindor), she knew better than to do anything that might get on Millie's bad side. If she had somehow slighted Millicent, a messed up bed would be the absolute least of her worries, and likely not even something she would consider as appropriate revenge. Which left just one…

And as she finished her thoughts, many things happened at once. First, Daphne completed remaking her bed. It stayed that way for less than a second before a loud popping noise echoed throughout the room and all of Daphne's hard work was undone. Second, as Daphne reached the conclusion that Pansy had done this, the selfsame girl entered their shared bedroom. Finally, as Daphne turned away from the noise (catching only a glimpse of her once again messy bed) and saw Pansy standing in the doorway, she let loose the scream that she had held back earlier.

"YOU UTTER BITCH!" screamed Daphne. "HOW COULD YOU DO THIS? WHY?"

Pansy raised an eyebrow, and then looked over Daphne's shoulder at her bed with a gleeful smirk. "Oh, you mean someone finally got tired of your little 'Everything must be perfect' routine that was stirring everyone's cauldron for the last few years? 'Fraid I can't claim that particular honor, but I'd love to meet the person who did."

Daphne reached for her wand, but Pansy already had hers up and waiting. "Don't pick a fight you can't win, Greengrass." The evil glint in Pansy's eyes told Daphne that her next move would cost her dearly. Daphne was quite afraid of just what spells Pansy might know (the Parkinsons hadn't exactly kept their family's history of Dark magic research quiet) when quite suddenly Pansy found an arm wrapped firmly around her neck and another pinning her wand arm against the wall.

"Wise advice, Parkinson; maybe you should take it next time," said Millicent Bulstrode, who had heard Daphne's scream and come to investigate. "Daphne, if you would be so kind as to grab her wand? I'd rather she not be able to hex us right now."

Daphne was still in a bit of shock, so it took a minute for Millicent's words to register. When they did, she gladly walked over and plucked Pansy's wand out of her hand. The urge to smash it on the ground or toss it away somewhere was strong, but Daphne decided she wouldn't want to deal with the consequences of that, at least not right now.

She watched as Millicent first conjured some ropes, then forced Pansy to sit on a chair, followed that up by tying the hatefully glaring girl to said chair, before standing back to admire her work. A quick nod of approval, and Millicent trained her wand on Pansy. She mumbled something Daphne was unable to hear, and then a jet of white light shot out of her wand into Pansy.

"I don't know exactly what happened before I got here, though I've got a good guess," Millicent said as she glanced over at Daphne's bed before returning her focus to Pansy. "So since you clearly need some answers, Daph, I'm giving you first crack at her. She'll respond truthfully to any question you ask, but you'll only get three questions worth of truth before she snaps out of it, at least partially. I'll ask my three after you're done, and then the spell breaks, and I won't be able to cast it on her again. So make your questions count. Am I clear?"

Daphne nodded her head, though she still looked a bit puzzled. "Before I ask Pansy what happened here, what spell did you hit her with?"

Millicent chuckled a bit. "I'm afraid I'm not at liberty to discuss just what that spell is, nor what it does, but don't fret, it's not Dark or anything. It just so happens to be a standard spell every Wizarding barrister has to learn before the Ministry will certify them, and as my dad is one of the best, he taught it to me so I could get into the family business once I'm done here. And that's all I'm legally allowed to say about it."

Daphne shrugged, knowing that was the best she was likely to get out of the situation. "All right, Pansy, question 1: why am I no longer able to make my bed properly?"

Pansy struggled for a minute before sitting completely upright and still. "I ordered one of my family's house elves to put an enchantment on the bed that makes it impossible for anyone to straighten it."

Daphne acquired a very annoyed look, though internally she was thinking ahead to what she could make out of the situation. "Somehow, I'm not surprised that you needed an elf to do that. Question 2: what was your goal from having that done?"

Again, Pansy struggled, but was made to sit upright. "I had hoped that by disrupting your perfect little life, I could wreck your standing within the House, and become the new Queen of Slytherin."

Daphne rolled her eyes at how transparent that was. She had finally decided how to get revenge on Pansy, but just to make sure… "Question 3: Can the enchantment on the bed ever be undone?"

Pansy shook and shuddered, not wanting to answer the question, but eventually she sat up, not quite as straight as she had before. "No, the only way to get rid of the enchantment would be to destroy the bed totally and utterly. And since I told my elf to tag the bed with an indestructibility charm as well, it's impossible."

Millicent then walked over to stand between Pansy and Daphne. "OK, Parkinson, now you're mine."

As Daphne didn't think she would be really interested in what Millie wanted to know, she gave her as much privacy as was possible in the same room, and called for one of Hogwarts' house elves. "Yes ma'am, you be calling Dippy?"

Daphne crouched to the elf's level and smiled gently. "Yes, Dippy, can you do a big favor for me?"

The elf nodded, so Daphne went ahead with her revenge plan. "Dippy, can you put a silencing charm on this bed, and then swap it with that bed over there?" Daphne pointed at Pansy's bed.

Dippy cocked her head slightly, but snapped her fingers. "Dippy has done as ma'am asked. Does ma'am need anything else from Dippy?"

Daphne shook her head, and the elf popped away. After testing the new bed to make sure that they had indeed been switched (they had, but Daphne wanted to be absolutely sure), she remade the bed exactly as she wanted it, and it stayed made.

"Perfect," thought Daphne.

A/N 2: The spell Millicent used is something I just made up for this story, as I didn't think there was any chance that what should be a controlled substance like Veritaserum would have actually been a reasonable thing to have one student threaten another with, even in Slytherin House.
