Chapter 4--Explosions and Ceiling Adhesion 101

What's up, Diary?

I'm on cloud nine. Really. Sirius is so nice to me, like he's never been for any other girl. Maybe it's just because he feels bad about the howlers I get from his "fan club", which is odd, because I find them hilarious. McGonagall is on a mission to find the sender, I could tell her who it was, I know who, but then I may not get them anymore, and I wouldn't want that. They are just too funny. Especially the one I got at one in the morning today. Lily didn't like that one so much. The Marauders latest prank was apparently in my honor, because when we went down to the Great Hall for dinner, everyone was laughing and pointing up at the ceiling. Turns out they had magically glued Broderick Thomas to it. No, really. It took four hours to find out how to get him down, and it turns out he's deathly afraid of heights. Even Lily was hysterical. Anyway, next week I'm going to be so busy. The dance is on Friday, Hogsmeade on Saturday, and we kill Slytherin at the Quidditch game Tuesday. The team is amazing this year, thanks to James Potter, Quidditch captain extraordinaire. I'm still the seeker, but Amber got picked as chaser, along with James himself, and Liz Kelner, a girl in 7th year. Sirius is a beater, and that new kid, 3rd year Joey Abercrombie, is too. He's great, but seems pretty nervous. Lila Smith is still keeper, and Amber was so happy when Remus got chosen as commentator. I hope he calls her some stupid pet name over the microphone. That would be- oh Merlin! I just thought of the greatest costume idea ever! Gotta go!

TTFN,

Adriyana

Dear Dumb Journal,

Just thought I'd tell you that the roses worked. I'm so glad they did, but I can't see why I'm even bothering to tell a stupid inanimate object.

-Sirius

"So…we don't need a Halloween prank? Why the bloody hell not?" James asked Sirius, who Remus was currently trying to stop from throwing his journal in the fire.

"I told you, Prongs, Adriyana's got it covered. You should see the costume idea she had. It's hilarious! I hope we can pull it off!" He responded.

"Any chance you'll tell us what it is?" Peter asked.

"Sorry, Wormtail, that's a surprise."

"Why?"

"Cause it will be funnier. Plus Moony will tell Amber, who will tell another girl, and soon the whole school will be stealing our idea."

"So your costume is the prank?" James asked, again.

"Yup," came Adriyana's voice from the door, where she had just appeared. "Of course, that doesn't stop you three from…blowing up all the pumpkins, or whatever." Peter and James exchanged maniacal grins and ran off, James in the lead. "And Amber's waiting for you downstairs," She pointed at Remus. He needed no further convincing and bolted down the stairs after them.

Sirius smiled at her. She was so amazing. What was even more amazing was the fact that she was actually going out with him. She was one of the few girls who had never thrown themselves at his feet. He actually had to work to earn her trust and now, her affection. It had been worth it, though, he noted, staring at her as she walked over to his bed and plopped down next to him. "Ow…still sore from that stupid detention …"

"Don't worry, eventually, you'll build up immunity to the pain. I did," he said, putting a supportive hand on her shoulders.

"Yeah? After how many detentions?" she asked.

"Er…396." He recalled. She groaned. "Well, your costume idea is amazing,"

"Thanks…you don't think we'll be expelled, do you?"

"Since when do I care?" he said, but he looked a little nervous.

"I think we should get a teacher's permission. What if we…." She broke off and looked around, then whispered the rest in his ear.

A smile spread across his face. "That'll work…wow…teacher's permission for a prank…never thought I'd see the day," he said.

"Oh, you guys are no fun!" James pulled off his invisibility cloak and stared at them "I try to find out your costume plans, and…ARRGH!" he stormed out.

Adriyana looked at Sirius. They both burst out laughing. Then she suddenly sat up, pulling the paper contraption out of her pocket. Sirius saw a flash of blue-green ink. She grinned." Sirius, I have to go… is that okay?"

"Sure…why?"

"Alice needs help with her costume. This should be good…"

He smiled at her. "Okay. See you later." he said, and she grinned and left the room.

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

"One of you give me a bra, you all have bigger boobs than me, I'll stuff it." Alice asked.

Adriyana started cracking up and went over to her drawer. "Sure! What color?"

"Hot pink…or red. No wait…red."

"I don't have either of those. Here, let's just change the color of this one. It's too small for me." She held up a yellow one and jabbed it with her wand. It turned a bright, flaming red.

Lily was on her bed. She managed to grab hold of a couple of pairs of fishnet tights and was making them into a top. Barely. Well, it covered the bra and most of her midriff. With fishnets. Whatever, she was a prostitute, right? Though she wouldn't be too surprised if it became Alice's favorite top. She would have to throw it in the fire after the dance.

Amber, for some very out of character reason, had a really short skirt lying around. She was cutting it even shorter and adding red sequins on. She had been reluctant to come, even though she was just studying with Remus in the common room, but, like everyone else, was getting really into it.

"Now, all we need is some sparkly red slippers like Dorothy, with higher heels, red lipstick, and LOTS of mousse." Lily said.

Alice smiled. "Brilliant! We can get the last few things the day of the dance, and we can stick more red sequins on these shoes." She held up a pair of white 6-inch heels she had just conjured out of thin air, she couldn't do colors or patterns yet, but was great at conjuring.

"Fantastic!" Adriyana responded. She took the shoes and turned them red as well, and then went over to help Amber with the sequins. Half an hour later, Alice stood in front of the mirror, shoving tissues down her bra, and looking like a total slut. She couldn't be happier.

"So…both of us have costumes, but what about you two?" Amber said, pointing at Adriyana and Lily.

Lily said, "I'm going alone. But I'm going to dress up like…I don't know. What are some good muggle costumes? Those are fun."

"Well, you can't go as a witch, obviously…you can't do a ghost, either, nobody will see you under the sheet…you're too pretty for that… how about…um…a devil?" Amber said

"Hmm…I like it…not as brilliant as you guys' costumes, though." Lily responded.

"Wait until you see Sirius and me. Our costumes will put yours to shame!" Adriyana said.

"Can we see it?" Lily asked.

Adriyana jumped off her bed and walked over to the closet. She had an idea for what would happen if they asked her…she would show them her costume…but not all of it.

She reached inside the closet and pulled out a set of absolutely gorgeous dark turquoise robes, with flowers sewn on them. The flowers were small and made out of sparkling crystals. They were shorter than most robes, which Lily guessed was the style for teenage dress robes, but still very elegant.

"Um, Dree? That's not a costume," Alice pointed out.

"It's pretty, but not a costume. Alice is right." Amber added.

"Oh. My. God. Sound the bells of England! Alice is right!" Adriyana called out. Lily laughed. Alice threw a pillow at Lily, afraid of hurting Adriyana's dress by throwing one at her.

"Besides, this is my costume. You'll see." She said.

"But how-" Lily began.

"Hey, I won't tell you anything else. Suspense!" she waved her fingers in the air, in an excellent interpretation of the divination professor. Before Adriyana could be asked another question about her costume, she left to take a shower.

The next day, Remus, James, Peter, Amber, Lily, and Alice were gathered in the Room of Requirement before Potions, trying to figure out what Sirius' And Adriyana's costumes were. "Okay, so it has something to do with turquoise dress robes…" Lily said. "That's all Adriyana told us."

"And it could get them expelled," added James. "I overheard them talking about it last night."

"And…it's good enough to be a prank all by itself," Peter added.

"What else did you hear when you were eavesdropping on other people's private business, Potter?" Lily asked accusingly.

"Well, er, they're going to ask for a teacher's permission, so they won't get expelled, I guess, but Adriyana whispered the rest of that part, so I couldn't hear," he said.

"Maybe something happens to the dress robes. They explode or something." Amber said.

"Nah, I can't see them getting permission for that one," James said. "But you maybe getting somewhere. It has to be something they can get permission for, but can also get expelled for." The whole thing was very confusing.

"So…something happens to the costume itself," Remus said.

"I think so, yes," James put in.

"Well, it did have a lot of crystals on it," Alice added. "Does that help?"

"Possibly, but both of their costumes do whatever it is. I don't see Padfoot wearing anything with crystals on it."

"He might do it for Adriyana," Remus said, but James shook his head.

"Still, it's pretty unlikely that his costume has crystals on it. I don't think Adriyana would want to be seen with him." James replied.

A thought struck Lily. "Maybe his costume has something else on it, and when that thing and the crystals touch, like when they're dancing, something happens."

"I think that's the best idea so far, Evans." James said with a smile.

"Yeah, Lily, I think you got something!" Amber added.

Lily blushed and looked down. She saw on her watch that they had five minutes until potions. They were on the seventh floor. "Guys, we have five minutes to get to the dungeons!"

"No problem, we can do it!" James said, as if he did this all the time. Which, actually, he did.

"What? We have five minutes to travel about a mile!" she exclaimed.

James grinned wickedly. "Good thing you're with The Marauders, my dear,"

The five of them burst into the room just as the bell was ringing (Peter, of course, wasn't accepted into NEWT level potions, it was a miracle Adriyana had scraped an E and got in by studying her head off).

Professor Slughorn greeted them and they took their seats. Adriyana and Sirius shot each other knowing looks. There was only one reason Lily would walk in at the same time as James. They were working on the identity of their costumes, and what's more, they were probably way off.

"So, today we will be working on this potion, here. I showed you it on our first day of the year. It's called Polyjuice Potion. It makes the drinker transform into the body and voice of whoever's little bits and pieces they add into it. Hair, toenails, what have you," Slughorn said. "Today you won't get very far, by the time you're done at the end of class your potion will not have the muddy look of this one," - he motioned toward his own cauldron – "but will be a light orange color. Instructions are on page 97. Begin!"

After class was half over, Lily and Snape, who was also in their class, had the only perfect potions. James and Amber ran a close second, but Adriyana's potion was worse than usual. Her potion was usually only slightly sub-par, but today it was an electric shade of tangerine and much thicker tan it should be. Whether her unusually terrible potion making skills were because she was really less intelligent or because Sirius was sitting next to her remained to be seen, though it was most likely the latter. She eventually gave up on her potion and settled for staring at Sirius instead. His potion was the right color, but was spewing out black smoke that was making him and Alice, who was sitting next to him, drowsy.

By the end of class, the Everyone but Sirius, Adriyana, and Slughorn had left class, and they were ready to put their plan into action. "You ask him, Agie, he likes you more," Sirius said.

"No he doesn't!"

"He does! He thinks he may get a pay raise for doing nice things for you, whereas I knocked out Alice with my potion's fumes today!"

"Fine." she said. She walked up to Slughorn's desk. "Er... Professor? I have a question for you," she said.

"Yes, Miss Dumbledore?"

"I was just thinking and," – she pointed to his cauldron of finished Polyjuice Potion - "I wonder if I might borrow some of that?"

A/N- Oooh…what's going to happen? Only I know for sure!
