)o( Remus's POV)o(

I glance at Sirius over the top of my book, my eyes wide and the wheels in my mind whirling. I place a bookmark and get up, walking over to a bookshelf that I tend to keep some of the more…prank oriented…tomes on.

"You do realise that if this works not only will we be in trouble from McGonagall, but also every Quidditch fan in the school and James?" I remind him.

"It would be well worth it! I mean come on, imagine the looks on their faces!" Sirius says, "And besides, Minnie will be thrilled."

I blink, "Ok, now I know that you're suicidal. McWhiskers is one of the biggest Quidditch fans in the school, she was chaser for Gryffindor when she was a student, and she was also the captain of her team for four years!"

"Exactly, and yet I somehow think that she will laugh her head off at this one. Come on Moony! We can finally do some of the bigger pranks, so why not? Besides if I can get Ann in on it then the three of us can work at it," Sirius explains.

"You do realise that this is not going to happen overnight, right?" I ask.

Sirius nods, "Yeah, but I've been talking with the squid and he said that he wouldn't mind."

"Fine, get Ann to agree and we'll work on it and get it done."

~*~ Ann's POV ~*~

I levitate the last domino into place and then place a spell on them so that no one can knock them down and ruin about five hours of work, and so that no one will see them until I'm ready. This is more for a little fun, especially seeing as that Sirius had been consistently chattering about this game that they learned in Muggle Studies and the different aspects of it.

"Hey Ann!"

I turn to see Sirius jogging up to me, "What did you do now?"

Sirius frowns at me, "I haven't done anything yet."

"Yet being the key word."

"Anyway, I was wondering if you would be willing to help me and Remus with a prank."

"But of course! What's the plan? And what are my experiences needed for?" I ask.

"You're charm work, and ability to master difficult spells rather quickly," Sirius says.

I nod, "Lead the way, and explain as you do."

~*~AG~*~

I stand in the empty class room and transfigure a desk into a large Plexiglas tank. The thing is twenty feet long and fifteen feet wide and eight feet tall. It's too bad that this prank is being kept secret from James, he is the best with transfiguration.

"Why couldn't you transfigure the desk?" I ask Sirius out of curiosity.

"Because I was not sure what Plexiglas is and seeing as that was what Remus said to make the tank out of I figured that you would know what it is and would be better for the job," Sirius explains, "Now we have to add the strengthening spells. Hopefully they'll work and we'll end up with a nice sturdy tank, or else we'll be cleaning water from this room and the hall frantically before a teacher shows up."

I shrug and start adding the spells. Three weeks of research has brought us to this point. The funny thing is that the professors haven't noticed that we're behaving more. Usually they do and start to freak out, knowing that a prank is afoot.

Remus enters the room right as we finish strengthening the tank, "Hey, that looks really good. There aren't any seams to it either, so that makes it a little studier. Want to start filling it?"

Sirius nods, "Might as well."

"Alright, let's hope that this works. Aguamenti!" I watch as the three of us start to slowly fill the tank and time it. The process is extremely tiring and I call for us to stop when the tank is a quarter of the way full, "We have to find a better spell to use. This is going to take too long. That tank is only two feet full and it took us thirty minutes."

Sirius nods, "Definitely have to find a different spell. Do either of you know what we can do to make the bottom look like the bottom of the lake?"

Remus's eyebrows raise and his mouth turns to a slight frown, "Do we even know what the bottom of the lake looks like?"

"Oh, yes I have a photo up in my dorm," I drawl, "We can work on that later, I want to see if the invisibility charm will work on the tank, or if there will be any adverse effects." Flicking my wand at the Plexiglas I start the spell and when I'm done give it the little stab. In a few moments it looks like there's two feet of water hovering about an inch off of the classroom floor.

"That's bloody brilliant," Sirius grins.

I give a mock bow, "Thank you, but you two are going to need to have the spell memorized too, because doing this on the actual one would be too much trouble."

Remus shrugs, "The invisibility spell will be the easiest to work on. After all, if you use a sicutme charm on the tank first then the whole thing should follow the one spell."

"I forgot about that spell," Sirius quips, "Wonder if aguamenti maxima would work at filling the tank any faster?"

"Probably, but it still wouldn't be fast enough for us to fill it in time," Remus points out, "aguamenti usually puts out about fifty gallons a minute, while aguamenti maxima puts out 150. We need something that's more around…500 or 1000. Maybe something even higher."

I bite my lower lip, thinking about a spell that would work for our purpose and coming up blank. I shake my head, "I don't know. Maybe I can find something in one of my books. I think that at worst we can use some sort of transport spell. I would rather not. After all we don't know what would happen to the lake if we take that much water out of it, but who knows?"

"Ah, but Ann! You can't spend forever buried in your books!" Sirius groans.

"Of course I can't. Did you forget that I'm giving you a sword fighting lesson tonight?" I ask.

"Umm…no…" Sirius tries to lie before sighing, "Yes. But in my defense, I was too excited about this."

I laugh, "Don't worry about it! Just be at the room by nine."

Sirius nods like an over energetic puppy before bounding away. I chuckle before placing my books in my bag. Remus sighs and walks out of the room, following Sirius and muttering about making sure destructive individuals don't annoy professors. Smiling at the thought my mind drifts to the way life has turned this year. Other than working on pranks and what happened at Christmas it's been a mostly uneventful year. Unfortunately, I feel as though I'm growing more distant from Rowan. He is with Regulus the most out of everyone, something that I'm both grateful and worried about. Grateful because I know that there are a lot of mini-Death Eaters around this school. And they aren't just in Slytherin either, though that house has the largest group. There are a couple of Ravenclaws and even some Hufflepuffs and Gryffindors. The main reason that I know is because Tessa brings them over during breaks and I can hear them talking about raids. This whole Voldemort thing is starting to really bother me.

"Watch where you're walking Grimwood!" Snape snaps at me, breaking me from my thoughts.

I look up in surprise, "Huh? Oh, sorry Sevvie."

"That's it? No curses to send my way? You aren't going to try and send me to St. Mungos?" Snape says scathingly.

"No, but if you keep comments like that up I might."

"Well where is your gang? I thought that you didn't go anywhere without Black, Lupin and Potter as your guard dogs!" Snape says with a smirk.

"Actually, if you think back, whenever you and I have fought it's usually one on one. If you have a problem with me then I suggest that you just say it outright right now, or else leave me be. I have better things to do than be annoyed by the likes of you," I sneer, dripping as much venom into my voice as possible.

Snape's eyes narrow and he walks away, muttering under his breath. I take a breath to calm my temper before continuing to the library. I instantly head to the charms section to look up something to help us with the prank and don't find anything in the section. I know that there has to be something on the subject in the library and move to one of the more abandoned areas of the library. Turning a corner, my eyes widen in shock at the sight in front of me. I can't even make a noise or move. Finally I manage a small 'eep!', before turning around and walking quickly the other way.

The sight of my brother pushed against the wall kissing one of the older Slytherin boys seems ingrained in my mind and I shake the thought away. They seemed so…attached. I really can't think of any other word to describe it. This isn't some light peck on the cheek or lips, but full out snogging. I knew that my brother was dating, though I think he's entirely too young, he'd gone with Deanna Vaintro to the last couple of Hogsmead trips before dumping her because she was turning clingy. Turning the corner I run into someone and fall to the ground. The person laughs as I grumble before looking up to apologize.

Sirius smirks at me, "Glad to see that I can make any girl fall at my feet."

"Ah, there's that lovely humble boy I was looking for," I say sarcastically.

"You know you love me," Sirius grins, "Now what's wrong? You normally pay attention to your surroundings unless you've been bothered by something, and then it has to be something really big."

I shake my head, "I just saw my brother snogging in the library."

"So?"

I grab him by the robes and pull him into a classroom before locking it and placing a couple of privacy charms up.

"You don't get it. He was snogging a Slytherin boy in the library."

Realization dawns on Sirius's face before he frowns, "So are you bothered by that he's kissing a Slytherin, or that he's kissing a male?"

"Neither, I'm just coming to the conclusion that I really don't know as much about my brother as I used to. From the events during Christmas, and now this, and everything else…I feel like I'm losing him, and I never even realised it. Never even thought about it. It seems like we're still close, but…There's something missing that used to be there," I mutter before shaking my head, "Sorry, I shouldn't be babbling to you."

"No problem, if you can't babble to me, who else can you babble to? What were you doing in the library anyway? I thought that I told you to leave that place alone for twenty four hours," Sirius chides.

"I was looking for a charm to help us in our prank."

"Ah," he sighs, "That explains it."

I nod and think about Rowan. It really has been too long since I've actually spent any time with him. The last time we spent time together one on one was before the Christmas holiday ended. And that had been a disaster. I thank Sirius and take down my spells before rushing down to lunch, trusting my brother's tendencies to act like a normal teen boy when it comes to appetite. Sure enough he's sitting at the Slytherin table with a full plate, and he's talking to the guy I saw him with in the library. They seem to be in an intense conversation, but I ignore that and just sit down across from Rowan, clearing my throat slightly. Him and about twenty other Slytherins in the area jump in surprise, looking at me like I'm psychotic.

"Hey Ann, what're you doing over here?" Rowan asks after swallowing his food.

I shrug, "I haven't seen my brother in ages. Are you busy at all later tonight?"

Rowan tilts his head back, looking up at the ceiling as though looking at his personal calendar before shaking his head, "Nope."

"Want to get together? Maybe play some chess or something?" I ask.

"Yeah, I'd like that. Oh! Ann, I'd like you to meet Kevin. Kevin, this is my sister Ann."

I look at the boy Rowan introduces. Smiling at him I offer a handshake, which he takes, wincing slightly at the strength in it.

"Nice to meet you. I'll assume you're a friend of Rowan's?" I ask, feigning innocence in the nature of their relationship.

The boy turns slightly pale, "Yeah, we're good friends."

I smile, "Excellent. I like knowing who my brother's friends are." I ignore his slight shudder and turn back to Rowan, "See you tonight at seven in the old classroom by Wendlyn the Weird, good?"

"That's fine, see you tonight!"

Standing from the Slytherin table I grab a sandwich and walk back toward the library. I still had a spell to find after all.

~*~AG~*~

I'm setting up the chessboard in the classroom as Rowan walks in. He takes off his tie and robes, throwing them to the floor and placing his bag on top and helps me to finish setting up. I smile and nod for him to take the opposite chair while I summon the butter beer I'd bought from Rosemerta earlier in the day.

"Ann…I'm sorry I've kind of been avoiding you for a while."

I nod, "Don't worry about it. I understand. So, anything happening in the life of Rowan Grimwood that I would find interesting?"

"Not really…"

"Oh really?" I smirk, "No one who's caught your eye?"

Rowan looks at me and blushes, "You know."

I nod.

"When did you find out?"

"This afternoon in the library."

"In…the…library?"

I glance up from planning my next move to see Rowan staring at me, his face pale and eyes wide. I nod again, and he seems to grow paler.

"I…uh…and…um…er…"

I chuckle, "Relax. I don't care. So long as you're happy. And so long as that boy knows that if he hurts you he's dead."

Rowan gives a smile. He's still somewhat nervous around me, then again, seeing your sister turn into a sadistic monster who enjoys using Dark Magic would do that to most people. And yet, he's starting to become as comfortable with me as he used to be. We talk for a while longer before I walk him to the Slytherin dorms and run back up to the seventh floor to give Sirius his sword lesson.

~+~ Sirius's POV~+~

I carefully walk through the halls, keeping as quiet as possible and keeping to the shadows as much as possible. I bend my magic around me to keep in a state similar to being invisible. I can hear Remus running a couple of halls down, he's using his senses to keep alert to where the teachers, ghosts, prefects, and poltergeist are. I don't know where Ann is, I can't track her, but I know that she's somewhere ahead of me and is keeping to the shadows far more easily than me.

The three of us exit the castle and make our way to the Quidditch pitch. After months of work, we're finally able to do our prank. Though, we can only hope that it will work. After all, this is not going to be a simple walk in the park, this prank involves plenty of really advanced magic, and I can only hope that we know enough and are strong enough to get it all done.

The gate of the pitch opens in front of me, seemingly of its own accord, and I walk in, with Remus following me, and Ann closing the gate. The three of us move to the center of the pitch and Ann and I unbend our magic and become visible again.

"Ok, so do we all remember the plan?" Remus asks.

I nod, "I'm going to work at transforming all these lovely pebbles into pieces of Plexiglas that will then be charmed to stick together along with the floor. I'm then adding the bottom layer to make it look like the bottom of the lake."

Remus nods and turns to Ann.

"I'm placing some wards and charms around the pitch to make it look like normal until right after the teams fly onto the field. Luckily they both like to fly around the outside of the pitch first, or else we'd have a bunch of players going splat," Ann says with a grin.

Remus nods again, "And I'm going to lay down the sicutme charm along with that water spell multiplication charm that I'd found."

"I still want to know where you found that. I'd looked everywhere in that bloody library," Ann grumbles.

"I didn't find it in the library," Remus smirks, "I found it in one of my personal history books."

"A history book? Really?"

"Yeah-"

"Ok you book worms, let's get to work, then you can go to reading heaven," I cut them off. They both give me mock glares before getting to work. I roll my eyes, wondering how in hell I ended up with two bookworms as friends. As if you don't read plenty of books yourself. Shaking my head, I give a slight grin as we all lay down the charm and spells needed for this to work. Once the base is done, I get to working on the pebbles, turning them into large pieces of Plexiglas. After they've been transfigured, I use strengthening charms on them and start to assemble them together, molding them so that there aren't any seams in the finished product. Upon finishing that, my next job is to cast spells so that the bottom of our tank looks like the bottom of the lake. It had taken three trips and a few mishaps with some Gillyweed before the three of us found out what that particular area of the school looked like.

After the entire job is done, the three of us sit in the stands and observe our masterpiece. It is pretty damn impressive. Remus pulls some butterbeer from his bag and passes the bottles to Ann and me. Sitting back, we toast to our success and hope for even more with a successful prank.

~+~SB~+~

I watch as James paces in the locker room, my bat swinging back and forth. He's way too nervous because he doesn't want us to play today. He doesn't think that the team is ready. He doesn't know he's going to get his wish of more time.

"Team listen up!" James says at last, "I know we're not all ready for this game. I know we all want some more time to practice, but we don't have that time. So, I want you all to give it your all in this one. Let's show them what Gryffindor is made of!"

The team leaves the lockers and I smile as I walk next to James. We're the oldest members of the team, having been on since third year, and James is one of the best Captains that we could have ever asked for. Of course, that also means that he's one of the most fanatical of us. Luckily, that seems to have calmed down some since fourth year.

As the team walks onto the pitch, they wouldn't let us fly around since apparently the teachers don't like it when things are thrown into the crowds (Though in my defense, the Slytherins were asking for it.), I smile, waiting for the signal. When I see a flash of purple in the stands, I send the trigger spell at the field, watching with a grin as the tank reveals itself.

It looks like water is bubbling up from the thin air. And that image isn't helped by the fact that the water in the tank looks like it is floating in thin air. The lake bottom looks spectacular and the squid swimming around is just the perfect detail. When the whole thing is revealed, I can't help but to smile. Then I notice James's expression.

"Well, it looks like you got your wish for us to get more time for practice," I say, grinning the entire time.

James glares at me, "Not what I meant Padfoot."

I smile and then notice McGonagall striding toward us, her eyes narrowed and lips pursed. James gives me a glare. I know that he's going to hate it if he gets in trouble for a prank that he didn't cause and that had interrupted his Quidditch.

"Relax James, you won't take the fall for this," Remus says from behind me. He has a certain satisfied look on his face that makes him look like the cat that ate the canary.

"Besides, everyone knows you'd never do anything against your precious Quidditch." Ann has a smirk on her face and is twirling her wand in her fingers.

McGonagall walks up, "Misters Black and Lupin and Miss Grimwood, follow me."

The three of us give salutes before following her in a mock march. That idea is soon abandoned when Remus tries to trip me with my own broom. I almost believe his innocent look before remembering this is Remus I'm dealing with. His innocent look always means that he had a hand in whatever the problem was. Giving him a glare, I stick my tongue out at him and am rewarded by him sniggering at me. Ann shakes her head at the both of us and somehow manages to almost get us caught in a trick stair.

Finally arriving at McGonagall's office, the woman orders us into the room and to take seats in front of her desk. And that's when there's a small crack in the armor. That's when McGonagall surprises all three of us.

"First of all, congratulations on the excellent display of magic that you showed today. I imagine it took quite a bit of planning?"

The three of us nod.

"While this is commendable, I would appreciate it if you showed that much effort in your homework. Second, I am disappointed that you interrupted the match. However this also turned out to be quite the educational experience for the younger students.

More nods, but also slightly heavy hearts. We were not aiming to educate, but to just cause slight amusement.

"Next, I would like to know why you thought of a giant fish tank?"

Remus and Ann turn to me, "We'd like to know that as well."

"Honestly? Couldn't tell you, because the idea just popped into my mind," I say, giving a shrug.

McGonagall raises an eyebrow, but continues, "Yes, well, in lieu of a detention, I want a three foot essay about what you did to achieve this prank and why it will not be done again."

Our heads drop and we sigh. I swear I hear McGonagall chuckle. That sadistic woman.
