I found this in my docs and apparently never posted it.
SOAP
Ruby fiddled with the mechanism of Crescent Rose, trying to pull out a branch that unfortunately got stuck in it. It was always the most annoying part of dealing with a mecha-shift weapon, and she should have been more careful. After ages of trying to pull the foul thing out, she managed to do so. With triumphant laughter, she threw the beast to the ground and stomped on it repeatedly to teach the branch a lesson for hurting her baby. She folded it back into sniper mode and placed it on a stand, heading into the living room. She let herself land onto the couch face first with a groan. Yang took a moment to look up from her scroll before going back to it.
Yang: Tired?
Ruby: Urgh. Yes, that branch was stuck in there. And I have to get some new parts as they are out of date now.
Yang: Are you heading out now?
Ruby let out another groan and shook her head.
Ruby: No, the place I usually get my baby's parts from closes at 7:00. It's 7:14.
Yang: Bummer. Sorry to pile on, but Dad's not coming home on time tonight; he has a lot of work to do.
Ruby: And I don't feel like cooking.
Yang: Me neither. Hey, when Zwei gets back from the Thornbush, we should order from that-
Yang was then interrupted by Zwei kicking the door open with a wide smile on his face.
Zwei: WHAT'S UP, YOU ASS FACE BITCHES! YOU STUPID ASS CUM-SUCKING SLUTS!
Yang suddenly went silent, her mouth becoming a thin line as she slowly turned to stare at her kid brother. Ruby sat up, her mouth agape as she tried to comprehend the AUDACITY Zwei had to say anything like that to his older sister.
Ruby: Yang.
Despite Ruby calling her name, Yang did not turn to look at Ruby, keeping her eyes on Zwei. Her hair slowly started to catch fire, her eyes red as well.
Yang: Yes, Ruby?
Ruby: My ears must not be working correctly. The child, he didn't just refer to us as 'Ass face bitches' and 'Cum-sucking sluts,' did he?
Yang: Hm. No, Ruby, your ears must be working because I heard that too. And what are the chances that both our ears aren't working?
The smile on Zwei's face faltered as it seemed his potty mouth didn't have the intended effect of making his sister laugh like he thought it would. In fact, despite the hot summer day and Yang's hair burning brighter and brighter, it felt oddly cold.
Zwei: U-ummm.
Ruby: Hmmm. Such disrespect and foul language from a child will not be tolerated.
Yang: It will not. Grab him, Ruby, and I'll get the soap.
Zwei: Soap?! Oh no!
Zwei tries to run back outside, but before he could take a step out of the door and use his semblance to boost away, Ruby activates her first turning into a swarm of petals, tripping him. She then turns back into her normal self and grabs him by his ankles, holding him upside down and marches upstairs toward the bathroom. Yang follows as he screams and tries to shake himself from Ruby’s grasp, but her grip on him is too strong.
Ruby: We're gonna wash that filthy mouth out, Zwei.
Zwei: NO WAIT PLEASE I'M SORRY
Yang: Not yet you aren't. We've been too soft on you.
Zwei (scared dog noises)
Qrow comes back to the Xiao Long/Rose household to the sounds of loud screams and sighs. He has a massive hangover and doesn't really feel like dealing with it, but was kicked out of the inn he was staying at due to his semblace breaking the floor, so this is his best option. He steps into the house and walks up the stairs to the sound of the screams.
Qrow: Do you mind keeping it down?
He pauses at the sight of Ruby holding down Zwei as he flails around trying to stop Yang from shoving a bar of soap into his mouth while he screams. All three of them turn to their uncle Qrow, with Zwei mouthing, 'help me!'
Qrow: Wha-
Ruby: He's being punished.
Qrow: Wha-
Yang: He called us a bunch of ass faces and cum sucking sluts.
Qrow simply blinks. He has no idea what on God's earth made Zwei think that was a good idea, given WHO his sisters are, and honestly, the pounding on his head makes him not want to dwell on it. He just lets Yang and Ruby deal with this.
Qrow: Well, just keep it down. I'm gonna sleep on the couch.
Yang: Can do.
Zwei: Uncle Qrow, please don't leave me here!
Qrow: Good night!
Zwei: NO NO NO NO! HELP!
Qrow closes the door on Zwei, leaving the tyke to have his potty mouth scrubbed by his sister. And hopefully, he'll learn a lesson: never curse his sisters out.
WHAT DID HE SAAAAY!? 😂 Yeah Zwei my boy, no one can save you now. You just gotta take your punishment like a man. You did this to yourself.
