Aria: Hello everyone! Sorry for the extremely long wait and thanks to all that have read this story and been patiently waiting for this chapter. However this is only part 1 and the second part will not be far behind :) This is possibly the longest chapter yet and I think that Isla will agree that it took lots of effort but it was fun.

Isla: Hey everyone, this was probably my favourite chapter to help write! I had so much fun coming up with ideas and developing the story further. I hope you enjoy it!

We don't own HP!

Enjoy!

CHAPTER 12 part 1– The Art of Secret plans and pranks

Previously in Chapter 11:

Dom explained, "Team A your on revenge weapon, Team B you're on look out and Team C you're decoys. That's the arrangement for Stage 1 of the plan and depending on what happens Teams B and C may switch jobs."

There was a chorus of agreement before Dom then said, "Who are we?"

"Weasley-Potter Girls!" we all say enthusiastically at the same time.

"Ok girls, let's go!" Dom stated authoritatively.

- The Next Day -

Rose's POV:

I had been unceremonially dragged out of bed very early this morning as Mya, Fie and I had to go to the Room of Requirement to start working on Stage 1 of the plan. When we got to the room we looked through the Potion and Charms books to find what we needed.

"Ok, so the potion for Stage 1 will take 10 minutes to complete and has to be used within 3 and a half hours after completed or else the potion won't work," Mya read aloud from a book, "geez no time pressure or anything."

"The potion for Stage 2 will take 2 hours to complete, that's 1 hours to make it and 1 hour to let it set and doesn't have a specific time limit for when it will become ineffective," Fie stated from a different book.

"The potion for Stage 3 will take 2 hours to complete but has to be left for 2 hours then stirred and then left for another 2 hours before it's ready, and will last 24 hours before it becomes unusable," I informed Mya and Fie looking up from yet another different book, "complicated much."

"Ok so here's what well do: tonight at dinner we'll make the potion for Stage 1 with allowance for time to get it to the location. And considering the potion for Stage 2 takes some time Mya and I can make that one in our free lesson this afternoon while Rosie is in DADA. Then after dinner we'll make the Stage 3 potion," Fie said.

"That's definitely logical. Now can we please go down for breakfast I am starving," I complained as my stomach grumbled.

"Yep," Fie replied with a slight chuckle in her voice.

We walked into the Great Hall, I searched the crowd for Dom and Team B and Team C. I spotted Roxy and Luc – Team C. I nodded as if to say we're-ready-to-start and they confirmed the same with a nod. Just before Mya sat down I saw her catch Lil's attention and the exchange of nods happened again. Dom was standing and observing the silent confirmation of the status of Stage 1. She gave the final nod that was the signal for the real action to start.

After that it was just the normal breakfast routine. When it was just before classes would start and the other students started heading to class, Mya joked, "Well I'll be off. It's time to confirm my terrible psychic powers."

"Amen to that sister," Fie agreed. She had never liked Divination because it wasn't certain, it was always changing and was too flexible in her opinion. I always thought it was just average.

Fie and I started to walk to Transfiguration – which Mya used to take before she decided to change subjects.

- The Divination Classroom -

Jemima's POV:

I was running late. I had gotten distracted and was outside the classroom having run nearly the whole way there. I took a deep breathe to calm my breathing and walked in.

"…And as you see this…" Professor Trelawney paused after seeing me standing sort of awkwardly near the door.

"Um Hi, Professor I transferred into this class," I said as confidently as I could.

"Yes yes, I knew dear, come and join us in today's lesson," She beckoned me to take a seat with the class. I quickly scanned the class to see if I knew anyone. Then the strangest thing happened. Al was sitting at the back of the class without a partner, and so I decided to be his partner. He didn't realise who he had been paired up with until I actually sat down next to him.

He had an surprised expression for a second before it turned into a smirk – no, focus Mya, everyone knows his smirk is the hottest but we're in the middle of class it is not the time to go brain dead.

"Hi, you never told me you took Divination?" I said making it sound like both a statement and a question simultaneously.

"Well I would have told you if you asked but I also didn't really want to advertise it either," He replied looking at me while he rested his chin on his hand and his elbow on the table.

"Well believe it or not I also choose Divination," As soon as I said it I realised that I had blurred out the first statement that popped into my head – which happened to be a lame statement of the obvious, great work brain.

He gave a sarcastic look and said, "No, I thought you were here to have some tea with me." Although I knew it was meant to be a joke his eyes turned slightly serious when he said the words 'with me'.

"That could be fun too," I replied with a smirk I couldn't hold back.

His face lit up but before we could continue Professor Trelawney said, "As I was saying before today we will be studying the art of palm reading, so take the hand of the person sitting opposite you and turn to page 242 in your books which explains how to interpret the lines."

I had been resting my hands on the table when Al gently took my left hand and turned it so that my palm was facing up. He turned to the page in the book and began to read and interpret.

"You will he kidnapped by a hippogriff tomorrow and watch out for falling cats," He told me. Wait…What?!

I must have had a shocked look on my face because Al started laughing his head of as quietly as he could. It was then that I knew he was joking.

"So what you're saying is lock myself up in the common room and carry an umbrella?" I sarcastically commented playing along with his joke.

"And don't forget to cast a hardening charm of sorts on the umbrella," He said with a small chuckle.

Then I notice I had this wear sensation in my hand. It felt like it tickled but it was calming at the same time. I glanced at my hand quickly to find that Al had been tracing little shapes on my palm that tingled my nerves. I looked up and was staring straight into his clear emerald eyes – could I melt right here, right now? Neither of us wanted to look away. I didn't even try to resist the urge to stare. I could feel the blush creeping its way onto my cheeks having his direct attention. Unfortunately every happy, blissful moment must eventually come to an end.

Professor Trelawney said, "Right now homework will be…." That's where I stopped paying attention as I notice Al had reluctantly let my hand go to write down the homework. Al and I causally chatted as we left the room but now I had to meet Fie for our little potions project.

"I kinda have to go meet Fie so we'll talk more later," I said.

"Ok see ya later," Al replied with a wide grin. Merlin he is so hot! I felt my cheeks redden so I swiftly left after a small shy wave.

- In the Defence Against the Dark Arts Classroom -

Scorpius' POV:

I was walking to the DADA classroom when I came closer to the door I noticed that Rose was ahead of me. She was at the door – which was closed – and didn't seem like she was going to stop to open the door. I jogged up to the door just before she walked straight into it.

"Yo, Weasley there's a door there you know, and unless you're a ghost you're not going to be able to walk through it," I sarcastically stated as I grabbed her elbow.

She didn't respond for a second but then looked at me with a blank expression and said, "What are you talking about Malfoy?" She tugged her arm away and opened the door.

Ok, what in Merlin's name is going on here? I thought very confused by her reaction and also went into the classroom.

The desks were pilled near the sides of the room as Professor Spearwood announced, "Today we have a dueling lesson so partner up, then make groups of four and the two winners duel."

I spotted Rose absently staring into space. This is not normal for Rose. She is usually focused in class. Now I am beginning to worry. I headed towards her hoping to be partners but a Hufflepuff girl got to her first.

Rose's POV:

I hope Mya and Fie haven't had any trouble with the potion. There are a billion things that could go wrong. Like what if a teacher finds out or what if Selene somehow finds out or what if James interferes. What if we all get detentions what would my parents think if I got a detention. What if the prank doesn't work or what if I make I lifelong enemy I don't know whether I could handle the stress. Merlin this is so bloody exhausting. Luckily lunch is after this. Wait…I have homework…damn I'll have to do it while I am brewing the potions for Dom's plan. Why can't it be lunch yet?

"Rose, um, is it ok if we are partners?" a shy girls voice stopped my brain rambling.

Wait…what's this about partners? I quickly realised that it's a duelling lesson in DADA today and Amber – who was a shy Hufflepuff – usually had a friend who she partnered with but she didn't appear to be here.

"Sure," I replied with a smile. Amber was extremely shy and apart from her friend Elizabeth she didn't really talk to many people.

"Do you mind if we join you to make to group of four?" a shortish Ravenclaw boy asked Amber and me.

"Sure Hunter," Amber replied shyly with her cheeks tinged pink.

"Who's your partner?" I asked.

"You must be blind Weasley," Scorpius stated appearing beside me. I glared in response to his comment and his smirk just grew so I decided to ignore it.

We find a space in the room and get ready in duelling positions.

"Expelliarmus!"

I dodged only just in time.

"Flipendo!"

Amber wasn't fast enough and got pushed back landing on the floor.

I looked over to see that Scorpius had already won his duel against Hunter. He was now intently watching me and had a conflicted look on his face.

"Alright, now the winners duel each other and the same goes for those who lost, and if it was a draw then switch partners," Professor Spearwood instructed.

I turned back to face Scorpius – who had that irritating smirk on his face – said, "I'm surprised you won Weasley, a troll could have done better than that."

A troll. A Troll! He did not just compare ME to a TROLL!!

"Excuse me!" I screeched. I readied my duelling stance and focus solely on beating Scorpius.

"Everte Statum!" I shot at Scorpius who blocked it was a defensive charm.

I continued with bombarding him with spells, "Locomotor Wibbly! Impedimenta! Petrificus Totalus!"

He blocked every single one then said, "There, that's better, that's the Weasley I know."

I was still furious that he compared me to a troll so I almost didn't hear his confusing statement but I was about to through another spell at him when he said, "Locomotor Mortis!"

I wasn't fast enough in my reaction so my legs ended up locked together which led me to fall over. After a second of surprise I sat up and was going to try throwing another spell but Professor Spearwood practically yelled over the commotion, "OK! Great job everyone! Today was a very good lesson but it is time to finish now!"

Everyone finished up and I did the counter curse to the leg-locking jinx and stood up dusting myself off.

"Thank you, you can go, see you all next lesson," Professor Spearwood thankfully dismissed us. I roughly grabbed my bag and stormed out of the room heading to Great Hall to pick up lunch before going to the Room of Requirement. Luckily Scorpius go caught in the crowd of people leaving class and didn't follow me. A troll, really, and he won the duel too, bloody slippery Slytherins and their smirks and annoyingness – yes it is officially a word now.

- Team A status: progressing well with plan…Meanwhile Team B is -

Lily's POV:

I was meeting my 5th year Slytherin friend, Penelopie – or Peny for short – in the Library. She has to update me on how the plan is going. I get to the Library and go to the back area to find the Molly is already there waiting with Peny.

"Hey," I greeted with a smile. It feels kind of thrilling to be doing secret revenge plans, no wonder the Sorting Hat said it was a hard choice between Gryffindor and Slytherin – not that I ever told anyone. It said that I had a lot of the reckless loud Weasley spirit but also had a secretive ambitious streak.

Molly cast the silencing charm. "So, did you find out her routine Peny?" I asked jumping straight to the point.

She nodded and replied, "Her last class today is Transfiguration then afterwards just before she goes to dinner she goes to the second floor girls' bathroom to redo her make up before heading to dinner. After dinner she goes to the fourth floor where she meets her boyfriend, Zac Tyler, and spends until about curfew – sometimes longer – with him. After that she has her shower and goes to bed. In the morning she wakes up at about 7:00 to have a shower then it takes her the next hour to get ready to go to breakfast at 8:30."

Molly had taken out a piece of parchment and had started taking down notes. I was confident that I would remember so I didn't take notes.

"Ok so that means that while she's in the bathroom we have to drop the potion on her," I said to clarify and Molly nodded in agreement. I continued, "thanks Peny, you've been a big help." She smiled in return.

"Lily, so that Lucy and Roxanne have an easier time distracting the WBBC maybe they should gather in one place?" Molly suggested.

"Yes, that's a brilliant idea, I'll round them up and sit them at the Gryffindor table close to Roxy and Lucy," I said.

We all nodded. We now had a plan, now we just had to tell the others.

"Molly you tell Lucy and Roxy the plan, I'll tell Rosie while she's getting lunch," I concluded.

"Ok tell Rose we'll meet her on the second floor before dinner and to bring the potion," Molly added and I nodded.

"Ok let's go tell them about the changes then we'll meet on the second floor after class before dinner," I said. We agreed and split up. I quickly headed in the direction of the Great Hall.

- Lunch in the Great Hall -

Rose's POV:

I was at the Gryffindor table just quickly grabbing a few things for myself and Mya and Fie. Then I saw Lily swiftly walking towards me. I knew it was about the plan so I finished grabbing a few things by the time she was at my side.

"Hey Rosie, how have you been? Has your day been good so far?" Lily asked trying to indirectly reference to the plan.

"Yep it's been good. What about you?" I asked.

"Good as well, oh and I am dying to tell you something I found out," She said sounding like she was talking about just normal gossiping but I knew better.

I nodded and we both left the Great Hall and where away from the Entrance Hall before she cast the silencing charm and informed, "Ok so Molly and I will need the potion not too long before dinner bring it to the second floor and we'll take care of things from there onwards."

I nodded and replied, "Ok I'll tell Mya and Fie, thanks. I'd better go see how they're going."

Lily had to go and I made my way to the Room of Requirement.

Lily's POV:

My mission was now to locate the members of the WBBC. I luckily found Louis, Fred and James easily as they sat at the Gryffindor table stuffing their gobs. I walked up to them and said with the most intimidating expression I could pull, "Three stay put or there will be hell to pay, ok?"

I received a mixture of shocked, curious, amused and scared – I must have really perfected my intimidating face. But I ignored their looks and straight away when to find Hugo. I found him with some of his friends in Hufflepuff, it took all of a second for him to agree to sit where I told him to. I actually had to look outside the hall to find Al and Scorpius but I also tracked them down quickly. They were cornered and being harassed by The Snake's lackeys – or that's what I like calling them but they were Selene's friends. Scorpius looked uncomfortable and bored, while Al tried to be nice but it was a loose-loose situation there. Then I had the most brilliant idea ever. Now I am usually a reasonable agreeable nice person but went it comes to The Snake's lackeys flitting with two guys who both unofficially have girlfriends, that's where I make exceptions.

So I walked right up to them and said, "Excuse me bitches," as I shoved past them and grabbed both of the boy's arms and start pulling them away.

One of the lackeys – Tremaine I think her name was, who has a boyfriend mind you – exclaimed, "Hey, what's your problem?"

"Sorry no time for conversations that waste my precious time, bye," I called after me and continued to lead Al and Scorpius to the Great Hall.

Once far enough away from those wanna-be snakes, both guys pulled their arms out of my grasp.

Al was the first to ask, "What the bloody Merlin is going on Lil?"

I again used my intimating look and replied, "Albus Severus Potter, you will do as I instruct or else."

The funniest thing was that Al actually looked scared. I would have laughed had I not had to keep up my act.

"Ok then Al I'll be going good luck," Scorpius said nervously.

"Not so fast Malfoy, you're coming too," I said.

"Why do I always get dragged into things like this?" Scorpius complained.

"Because you are considered part of the family so stop your whining," I replied sternly.

"Okay," he replied with a small smile having given up arguing with me.

"Let's go to the Great Hall we're missing Lunch," I said and started walking to the Great Hall.

Albus' POV:

Geez, Lil can be a bit frightening sometimes…like mum. Only I've never seem Lil ever actually seriously angry like mum has been before. We approached the Gryffindor table to where I saw James, Louis, Fred and Hugo were all sitting together – this is a bit odd because the WBBC rarely all gather and eat together, we would usually be scattered around. Was Lil rounding us up? Why? My baby sister was definitely up to something, I just wasn't sure what that is yet. Scorp and I sit and Lil gives a stern nod and leaves the Great Hall.

"Does anyone else feel we were just rounded up like cattle?" Fred questions while thoughtfully chewing on a bread roll.

"I don't think I've ever seen Lil quite so stony," James commented with a hint of concern for our little sister.

"Where did she go?" Scorp asked – though it was more like a statement and he didn't expect us to answer.

"Who knows, anyway this could work in our favour now that we're all here we'll organise our strategy to follow them," James optimistically said.

I heard Scorp groan and I grimaced at this idea.

"So we'll…."

- Meanwhile in the Room of Requirement -

Rose's POV:

I had told Fie that the plan had to be changed slightly and that now we had to have the Stage 1 potion finished before dinner. With that change in mind we agreed that we should probably start the potion for Stage 3 during dinner – although both my mind and stomach protested strongly at the thought of missing dinner. Mya, Fie and I have been busy brewing non-stop. We each take turns in the main cauldron so that one person can take a break every now and then. On my break I had done homework otherwise I wouldn't get anytime to do it. Right now I was chopping up and collecting ingredients to give Fie who was currently stirring the contents of the cauldron while Mya was napping.

"Pond slime," Fie stated and I passed her the bottle, "Horned slug and Ginger," I levitated the Horned slug – it's not like I'm gonna touch it, would you? – out of a jar and into the cauldron and then passed her the Ginger bottle.

This process was the same for a while. The only difference was that we would rotate.

"Stage 1 potion done," Mya exclaimed with glee and pride as she poured it into a decently sized bottle.

"How long until dinner?" Fie asked.

"About 20 minutes," I replied. "I have an idea. How about I run down and give the potion to Lily while you two start the last potion and look after the Stage 2 potion," I suggested.

"Sounds like a brilliant idea," Fie commented as she passes the potion to me.

"Ok, I'll be back soon," I said heading towards the door.

Mya joked, "Where else would you want to be?" I couldn't help but grin as I left the room.

I swiftly made my way to the second floor doing my best to be discreet. I saw Lil standing near the door to the girls' bathroom.

"Rose do you have it?" Lil asked looking excited, nervous and relieved simultaneously.

"Yep," I answered as I passed her the medium sized bottle.

"I'd best get back to my team, good luck Lil," I said and gave her an encouraging smile. Team B – Molly and Lil – got one of the harder jobs: actually doing the prank.

She nodded and I hurriedly made my way back to the Room of Requirement.

Lily's POV:

I watched Rose walk away then entered the bathroom. Most of the mirrors were murky and some of the sinks taps had a little rust except one – which I presume The Snake uses, she must have fixed it with the repairing charm. Molly was looking around to find a good spot to pour the potion on The Snake without being seen.

"I could levitate myself then pour it over her head or I could levitate the bottle while you levitate me," Molly suggested as her top two options.

"The first will work better, I'll stay on look out while you get yourself ready," I said.

- At Dinner time in the Great Hall -

Scorpius' POV:

We – the WBBC – had just wasted about 2 or 3 hours of our lives on a pointless wild-goose chase. I realised this the same time Roxanne – who Al, James and I had to follow while Fred, Hugo and Louis followed Lucy – walked into a classroom, to then walk straight back out again through a different door. I now sat exhausted eating dinner and reflecting on the hours I will never get back.

That aside I looked around and notice that Rose, Mya and Fie weren't in their usual spot at the table. If it's one think you can always rely on with Rose is that she will never miss a meal. I have been here even before dinner started and Rose hasn't come yet. Now I am worried. What could be so important that Rose would actually miss a chance to eat? It must be some sort of life and death situation. Maybe I'm just paranoid. She probably fine. I am probably overreacting…probably…

- Second floor girls' bathroom at dinner time -

Lily's POV:

I just watched The Snake go into the girls' bathroom from down the hallway not many people where around so I had to hide around the corner. After she had walked in I went closer to make sure no one else went in yet. I casually milled around for a minute or two until I heard the funniest sound I have ever heard and will never forget.

"ARHHHH! EEEEK!" The Snake bust out of the bathroom with an orange substance – which was the potion I assume – all through her hair and dripping down her face onto her clothes. The orange was as bright as an orange – the fruit – but seemed to become darker and murkier over time. She was livid with her face scrunched up in anger. I was trying very very hard not to laugh. Trust Rosie, Mya and Fie to come up with a potion like that, Ha Ha!

The Snake stormed quickly down the hallway avoiding people's gaze. Molly came out a second later and we followed her all the way back to her the Slytherin common room. Stage 1 complete.

"Great job, Lily, Molly," said a voice from behind us. We turned to see Dom.

"Where were you all this time, Dom?" I asked curiously.

"Helping Roxy and Lucy with the WBBC," Dome replied with a smile then in a whisper she said, "looks like Stage 2 is underway have you got your part organised?"

"Yep," I replied.

"Excellent, well I'll be around if you need me," Dom stated with a smile and walked off.

Soon after Dom walked off Al and Scorpius were casually walking to their common room until they spotted us.

"Lil? And Molly? What are you two doing outside the Slytherin common room?" Al asked as if he concluded that we were suspicious.

"We're waiting around for one of my friends," I said matter-of-factly.

He seemed unsure and then said, "Ok…oh yeah where did you go after you left us in the Great Hall? You seemed to be in a hurry."

"I had other places to be," I replied.

Both Scorpius and Al seemed to pick up that I was avoiding telling them something.

"Were you with a boy," Al asked with his protective big brother attitude coming out. Really? Just because I gossip and sometimes flirt doesn't mean I with a boy every time I want to be alone. Is a little quiet time too much to ask for? I decided that to keep Al off the topic of why we're here I would play along with his assumptions.

"What does it matter to you if I was?" I asked pretending to hide a non-existent meeting I had with a non-existent boy.

"Who is he? How long have you been seeing him? What house is he in? How tall is he? What subjects does he take? And most importantly have you kissed?" Al bombarded me with a full on interrogation.

"Wow, just stop, firstly what the hell gives you the right to knowing any of those answers!" My voice had gone up an octave. I was a person that liked the policy of if-I-don't-tell-you-then-you-don't-need-to-know.

"Because I'm your big brother," He answered trying to sound confident in his lame answer.

"That is the lamest excuse I have ever heard, and secondly I lied I was with Molly the whole time, right Mol," I said. Molly had taken out a book and had started reading when Al had started his interrogation. She looked up from her book and offered a small smile.

"Yep, we've been hanging out all day," Molly said.

"That's right, we've had a great day of cousinly bonding," I added.

Both Al and Scorpius looked like they were trying miserably to contain fits of laughter. I knew exactly what they were thinking: Gossip Girl and the Scholar spending a whole day together bonding, not a chance.

"Ugh," I said annoyed and grabbed Molly's arm to hide further down the hallway until someone from Team A brings the potion for Stage 2.
