Note: I'm trying to get this done as soon as possible so I can work the other few ideas I have in my head. As such you can expect to see an ending to this story much later tonight into the wee hours of the morning. Enjoy.
Ruby was having fun, in what seemed like forever. She was drunk, she looked like shit, she was full of cheap food, and happy. It didn't matter that her toilet may have been lit on fire, someone drew inappropriate picture on her wall, guys was fighting in her backyard, and she kissed a few guys or girls. Her sister promised her a party and she was getting way more than she bargained for. The moments Ruby woke up that Friday to get Weiss good and gone were worth it, even if she couldn't explain the extra food, the sudden cleaning of house, why she was removing certain flammable objects from their living room, the sudden increase in alcohol around, why Jaune and Nora would call only to suddenly hang up when Weiss answered, or the complex lock Ruby placed on the heiress' door right before she left. But lucky for Ruby, Weiss didn't care enough to question her.
"I suppose Yang will be coming by later," Weiss mumbled as she took inventory of the Grey Goose and Blue Moon Ruby left in the kitchen. Weren't they supposed to check IDs for this? Ruby is underage. "Just as long as Blondie stays out of my room…"
The plan was actually going off without a fail and for once in a long time, Ruby was having fun. It initially took a lot of convincing from Yang and Nora to enjoy the party. While everyone was dancing to DJ Kitty Scratch (Don't ask Blake why) Ruby was busy running around the house hiding paintings and Weiss' expensive glass figurines, keeping fights out the house, adjusting the wiring in the basement every so often so power didn't go out, and making sure no one was running a brothel in the heiress room. But after putting out a backyard fire for the third time that night Ruby gave in, grabbed some cheap beer and joined her sister against Jaune and Pyrrha in a dance off. The moment she took a swing of liquor the stress washed away. It was all fun, up until Weiss walked in the door.
Lucky for party goers their DJ was currently playing a pre-made playlist for people to dance to so she could take a break. Unlucky for the party planners, no one else in attendance notice the immediate danger they were in, except Ruby, the topless dancing buffoon that was Yang, and Blake, who had almost considered abandoning her turntables and computer to run out the back. She ran track back in high school so was sure she could make across state lines by daybreak.
"Weiss!? Hi…" Ruby was slurring in her speech but trying her hardest to sound normal, forcing the biggest smile she could. Ruby found herself shivering at an unexpected temperature drop the closer she got close to Weiss, but swore she had the heat on. Was Weiss giving off this chill? "You're home…early? H-how was Deer Ring death of Niberberg?" Ruby was unsure what the opera was called, much too impaired to remember correctly and much too scared to ask Weiss for the correct title.
Weiss held an expressionless face as she looked Ruby up and down. Messy hair and sweaty red hoodie from dancing; ripped jeans and a bruise or two from a fist fight, a bottle in one hand, a vinyl record in the other, and some guy hanging off her shoulder in a surprise hug. She then examined her house. Someone was smart enough to remove all the pictures from the wall but forgot to spare the various vases and figurines from the same faith as noticed broken glass and ceramics everywhere. The couch looked as if it has seen better days, half the lights were working and kitchen looked like the aftermath of an atom bomb; and was that a male's…instrument drawn on the wall next to a pair of donuts making love?
"Weiss it isn't as bad as you think I mean it looks bad but we just invited some friends over but I promise you I'll clean up just don't—" Ruby started to spill as she found herself quickly sobering up under Weiss' icy glare, if you can call it that. The girl was sure Weiss' eyes were turning as black as Blake's hair.
"I need a drink." Weiss muttered.
"W…what?"
"The bottle Ruby!" Without wasting any movement Weiss took the bottle and record from Ruby's hand before shoving the Ruby's friend to the floor with a hand in his face. Slowly walking to the staircase Weiss took a swig before stopping by her kitchen to grab something stronger, effectively freezing Nora and Ren into place, the former of the two who was pigging out on pizza. Weiss threw Ruby's bottle in the sink and took a whiff of her new one. This would put her to sleep pretty quickly.
Walking out the kitchen taking a hit of the stronger drink, she passed a flustered Jaune and dropped in his hands a pack of breath mints. "For when you kiss her", she whispered, nodding to a red head built like a Spartan girl across the room. Walking up to and behind the DJ table Blake was hiding in Weiss thumbed through a crate of vinyl records until she came to one titled Cosmogramma, handing it to Blake with the instructions to play it next. With one last swig of alcohol Weiss almost threw Blake the bottle, walked up stairs, and into Ruby's room, once she discovered she was locked out her own.
Fatigue took over quicker than expected, the alcohol Weiss consumed to help her sleep was kicking in, and after locking Ruby's door she jumped into her house mate's bed and fell asleep, the scent of roses soothing her more than the music caused a headache. She'd let Ruby enjoy the party now, and let her get all the excess energy out her system. Because come tomorrow morning, she'd kill her, and she wanted her prey hung over and too weak to flee.
