A/N: I thought this was going to be a short chapter but it turned out to be the longest so far. Weiss' big prank will be revealed next chapter but until then you'll just have to guess what she has planned for Yang. There's pranks, Cardin being his usual charming self and a game of dares ahead in this chapter so enjoy.

Thursday Morning- Ruby

Shaking slightly, Ruby placed her scrunched up fists onto the desk. She watched Cardin reach over to the row in front of him and flick Velvet's ears again and felt a boiling anger bubbling somewhere in her stomach. They were yet again in a boring grimm studies class with professor Port but Ruby couldn't take notes when she was a witness to such discrimination only a row across from her. She was about to shout out something, she wasn't exactly sure what, when Yang burst into class late. "Sorry I'm late sir!" she exclaimed merrily.

"Oh that's okay child, just sit down wherever. Now where was I?" As he droned on again Ruby caught Cardin making rude gestures to her sister obviously in an attempt to get a reaction. However Yang just sat down next to Velvet and ignored him. That was surprisingly mature Ruby pondered upon Yang's patience when she noticed Cardin lean forwards yet again to poke at Velvet's ears. However this time Yang's hand intercepted his, he let out a hiss at the contact withdrawing his hand and inspecting it closely. Ruby almost laughed out loud when she realised that Yang had given him a literal burn. With the coward temporarily scared off Ruby felt her eyelids becoming too heavy to hold open anymore. The room was so warm and professor Port's voice was almost soothing with its deep tones…

'Smack!' Ruby jolted upright and awake at the slap to the wrist she'd received from Weiss. "Sorry" she mumbled at the dismayed heiress whom she just realised she had been leaning on. Was that a blush from Weiss? Probably not. With a check to the clock Ruby realised that class was almost over, finally!

Ruby's joy was short-lived however as she heard Cardin viciously threaten Velvet "You can't always have your traitor girlfriend around to protect you."

"Velvet is too noble to fight you though I know she could beat your sorry ass easily, just remember that I have no problem with forgetting about being noble Cardin." Yang warned as he left the class. "How do you stop yourself from kicking his ass?" She asked Velvet.

"W-well he's very big I don't know if I could beat him."

"Ha! He's really not that great in a fight and I heard you've got some cool mage stuff going on anyway."

"It's like you have superpowers!" Ruby excitedly joined in.

Thursday Evening- Weiss

That girl was incorrigible! Yang had not only performed more pranks all week but had also not been phased by any of Weiss' attempts at tricking her. When she had stolen Yang's towel she had merely strutted out of the bathroom in all her naked glory much to the embarrassment of the rest of the team. Weiss could feel her cheeks heating up just thinking about it, "If you wanted to see what was under my clothes you only had to ask politely princess" Yang had stated as she gathered the towel off the dorm room floor.

Ruby had covered her face and ears with her pillow whilst shouting "la la la. This is not happening. Happy place. Happy place."

Weiss' eyes had almost bulged out of her sockets as she averted her gaze and muttered about decency.

However Blake had simply laughed and told Yang to "stop traumatising them" as she opened up a novel. It was rather mortifying for Weiss to have an attempted prank backfire on her like that and if anything it made her more determined to succeed than ever.

"Ruby I've been thinking that even though I said I didn't want Yang to get into trouble I feel like she's been getting away with too much recently."

"What do you mean?" The red clothed girl asked in a hushed tone from the library sofa.

"She does all these pranks but never gets caught! She rarely gets detention so I was just thinking that maybe our prank could get her into a bit of trouble but obviously nothing too serious."

"Hmmm. I don't know Weiss. It seems sort of dangerous to me."

"Though I fear how much I may sound like Yang right now, don't you have to take risks to prank well?"

"Well what did you have in mind?"

Friday Morning- Yang

It seemed to happen in slow motion. Yang slammed her locker door shut with her usual gusto causing the precariously balanced bucket on top of it to begin to topple, the very bucket which had been purposely placed above her locker and filled with sloppy green goo. With a tragic inevitability Yang watched in horror as it fell and covered most of her front. It was wet, cold and sticky. A combination rather undesirable when faced with a long school day to get on with. Yang also heard the tell tale snickering of a certain bigoted ginger haired bully who winked at her before sauntering away.

"Damn you Cardin Winchester!" Yang cursed whilst wiping herself off to the best of her ability but ultimately just spreading the green mess around her body. So he's trying to play me at my own game. She gave up on getting to class and went to clean up. Oh it is on.

Friday Afternoon- Blake

"Please help me Blake." Yang asked for the tenth time in the last five minutes they had been sitting in the library.

"No." She replied again trying her utmost to focus her eyes on the page and not on the puppy dog eyes her partner was now casting her way.

"But Blake he got green mess in my hair! In my hair!"

"Shhhhh!" The librarian sternly told Yang.

"I need your back up for this. I've got an idea and it will only get me in trouble not you and it will totally be worth it." Yang continued to try and convince her.

"How much trouble will it get you into?" Blake inquired finally giving up on trying to read.

"I'm not sure, it's hard to gauge, but it will be obvious to everyone that it was me who got him or at least had something to do with it. I mean like really really obvious but at the same time I could claim that there's no solid proof so I don't know if they could actually pin it on me especially if you helped me. Then I could make sure I had an alibi."

"I cannot fathom how these ideas form in your mind."

"So? Will you help me out? I could do it on my own but it would be better with your help. We'll call it 'operation payback time'." She made those pleading eyes again. How does she do it?

"I will consider it."

"Awwww thanks Blakey!" At that Yang threw herself across the table and grabbed Blake into a crushing hug which seemed to be the final straw for the librarian who insisted Yang leave immediately before she disturbed anyone else.

Friday Evening- Ruby

"What do you want to do Weiss?" Ruby asked as teams RWBY and JNPR gathered in a circle on the floor of the latter's dorm room.

"I honestly don't mind Ruby."

"Well that's a first." Yang commented receiving a glare from the heiress in question.

"We could see who can jump the highest on the beds!" Nora suggested.

"I don't think we're allowed to break anymore beds Nora." Jaune said.

"Oh, what have you guys been up to in here?" Yang questioned with a waggle of her eyebrows.

"Yang!" Everyone scolded.

"We could just watch movies on someone's scroll until we all get too tired?" Ruby suggested.

"Sounds good sis but first why don't we have a little game of truth or dare?" Everyone seemed okay with the events that had just been planned out for the evening and it was highly likely that with the amount of cookies and other sweets they had stashed they would not be going to bed any time soon. At least they could have a lie in tomorrow.

"Alright guys I came prepared." Yang announced as she whipped a hat out from behind her with a load of paper slips folded up and placed inside. "I looked up some interesting dares and thought some of my own up and put them into this hat. So it will be random what dare you have to do and if you really want to you can chicken out or maybe have a second dip in the dare hat."

"You were carrying a hat full of dares around with you?" Blake looked like she didn't even find that surprising anymore.

"Yes. So let's get this party going! I don't care about truths so we will simply take it in turns to pick out of the hat."

"Yang they aren't all inappropriate are they?" Weiss asked uncertainly.

"No well a couple are sort of but they're pretty tame mainly just silly things, don't worry about it. Let's make a pact that nothing leaves this room okay? If anyone has to do something embarrassing at least they'll know that their secret is safe with us." Most people nodded but knowing that Yang had picked out the dares was rightfully making many of them nervous. What have we just agreed to?

Later On That Evening- Ruby

"Let me just get a pair." Jaune left the circle to root in his closet and returned with a pair of his tighty whiteys, "So I have to wear underwear on my head for the rest of the game?"

"Yup. Looking fine there Arc." Yang confirmed. "Your turn Ruby."

"Okay," she picked out a slip and read it aloud "feed the person on your left a cookie without using your hands." She turned her head left to face Weiss who was looking particularly mortified by the end of the sentence.

"Uh, h-how do I do that?" Ruby questioned. She doesn't mean…?

"She's so adorable!" Yang gushed before picking up a cookie and shoving it in her sister's mouth, "now feed the princess."

It had gotten gradually less embarrassing as the game wore on seeing as everyone had been subjected to crazy dares but Ruby couldn't help the bright blush that she could feel blossoming on her cheeks and neck as she faced her equally stunned partner. Well she wasn't going to chicken out; Yang would never let her forget it. So she edged closer. And closer, until their noses were almost brushing together. From this close Weiss' eyes were a vast sky which was the blue of a perfect summer day and Ruby couldn't help but admire them. She then realised that Weiss seemed to be stuck still in shock and hadn't opened her mouth at all to receive the cookie that Ruby was now bumping against her lips.

"Open up." She mumbled around the biscuit, this got a loud guffaw from Yang causing Weiss to be startled back into reality and quickly bite down and chew. Ruby finished the cookie in her mouth as they leaned away from each other both intent on not making eye contact for possibly the next year.

Later On That Evening- Blake

Blake couldn't keep the smile of her face as she looked around the circle; Nora was wrapped up from head to toe in toilet roll as she was a 'mummy' for the game, Ren was sporting some nice pink lipstick and Jaune was still wearing his underwear over his blond locks.

She picked out a piece of paper and read it aloud, "Play the next round whilst sitting in the lap of the player on your left." She turned left and gave Yang a raised eyebrow; in return she got a grin. Yang gestured for her to come closer to which Blake rolled her eyes and scooted over slightly. It was Yang's turn to roll her eyes and then grab Blake's waist and pull her onto her lap. As Nora gleefully took a dare and announced that she was to give Ren a back massage Blake mumbled "you set this up."

"Set what up?" Yang feigned innocence as she pulled Blake closer to her chest.

"Have you got any other matchmaking dares in there?"

"Maybe one or two, Jaune really needs to make his move on Pyrrha." Blake nodded in agreement and subconsciously snuggled closer to Yang as she realised just how warm she was.

After reading his dare out Jaune awkwardly stood up and helped Pyrrha to her feet as Yang played some cheesy love song from her scroll. "Okay guys slow dance it out." Jaune timidly placed his hands on his partner's waist and they stepped around slightly until the inevitable happened. Jaune scuffed his shoes and would've pulled them both over if it wasn't for Pyrrha's reliable and steady grip on him. "I guess you should stop before you injure someone." Yang called up at them which earned her a scolding look from Blake who had mysteriously failed to retreat from her lap even after the turn was up.

"You had to ruin their moment didn't you?"

"Was it like in one of your romance novels?" Blake blushed deeply at that, has she been reading my books? She decided to change the subject.

"When do you want me to go and do 'operation payback time'?"

"You'll have to find a way to excuse yourself in a bit, I think it's probably late enough that sleeping beauty will be living up to that title by now." Yang replied.

"And you're certain he will sleep through anything?"

"Yes, how else would someone as heavy handed as me have been able to super glue ears to his head? Look, if you're having second thoughts I don't mind if you don't want to do it anymore I won't even call you a chicken." Blake smiled, there was just something about the way Yang thought and phrased things that made her so much fun to be around.
