[RWBY] The Great Temporal Step-Sibling War!

[AndrewJTalon]

Radian, Vale
Three years after Salem's defeat
- - -

The rain drummed steadily against the roof of the cozy house Jaune had built with his own hands years ago, a sturdy place tucked into the Arc lands inRadian. Warm lamplight spilled across wooden beams, mismatched rugs, and the kind of clutter that only comes from children and love and too many people trying to live full lives under one roof. Yang sat in the big rocking chair Jaune had carved for her, Baby Pyrrha nestled against her chest, tiny fists clutching the front of Yang's oversized sweater. The little girl babbled softly—"Mah… bah… bwam!"—and Yang rocked on, slow and steady, eyes fixed on the front door.

Xia, their eldest, kept peeking around the corner from the hallway, clutching her stuffed Ursa. "Mama… when's Auntie Ruby coming home?"

Yang forced a smile, the kind that didn't quite reach her eyes but was good enough for a four-year-old. "Soon, Firelight. Soon." The last word slipped out quieter, almost lost under the rain.

Xia pouted dramatically. "She's so cool!"

Pyrrha blew a raspberry in agreement.

The front door finally creaked open. Jaune stepped inside, soaked through, blond hair plastered to his forehead—and Ruby cradled in his arms like a bride who'd forgotten how to walk.

Ruby's face was scarlet. "Jaune! I can walk just fine!"

"Yeah," he said, kicking the door shut behind him, "and you're not supposed to be walking at all."

The scars across his neck and chest—bite marks from Yang's dragon form in the worst days, claw gouges from Cinder's final, desperate swing—stood out stark under the lamplight. He still smiled, though, exasperated and fond in equal measure as he set Ruby gently on the couch.

"DADA!" Xia launched herself at him.

Jaune laughed, scooped her up after depositing Ruby, and hugged her tight. "You stay," he told Ruby, pointing one long finger.

"I'm not gonna—"

"You stay."

Ruby pouted harder than Xia ever had.

Xia immediately clambered into Ruby's lap. "Auntie Ruby! Tell me more stories!"

Ruby hesitated, then softened. "Well… I could tell you about this Arachne I fought once…"

Yang caught Jaune's eye over their daughter's head. He gave her the grim little nod they'd developed over years of silent communication: She's doing it again.

Yang clenched her fist until her knuckles whitened. Scales flickered briefly across her forearm—black and shimmering—before she forced a slow breath and watched them fade.

She mouthed, I'll talk to her.

Jaune mouthed back, I know.

He crossed to her, kissed her cheek, ran a gentle hand over Pyrrha's downy head and then over Yang's swollen belly. Yang gripped his fingers hard, leaning into the touch like it was the only solid thing in the room.

Pyrrha nuzzled between her parents.

Yang smiled despite everything. "She almost called me 'mom' again."

Jaune's eyes lit up. "Really?!" He knelt down and held his daughter with a grin.

"Come on, Pyr… Dada! You can say it. Dada!"

"Daaaa… Dwah… Pffft!"

Yang laughed softly. "Yeah. I'd say that counts."

Jaune sighed, mock-tragic. "One day…"

Xia piped up immediately. "Dada! I said it! Can I have ice cream?"

"Sure, sweetie." He lifted Pyrrha into his arms and let Xia take his hand, leading them both toward the kitchen. "Chocolate?"

"Chocolate!"

Ruby watched them go, expression caught somewhere between wistful and guilty.

Yang turned to her sister, channeling every ounce of disappointed-big-sister energy she possessed. "So. Have you got anything to say for yourself, young lady?"

Ruby blinked. "What are you talking about?"

"Oh, is that how you wanna play this?"

Ruby tried innocence. "Play what? I don't know what you're talking about."

Yang took a long, slow breath—careful, deliberate, because the baby (babies, her brain corrected smugly) did not need her losing her temper.

"We agreed—after your stitches popped earlier this week—that you were staying in bed until we were sure they wouldn't open again."

Ruby shifted. "I just… heard about a Grimm sighting outside the main wall. Papa Nick's still laid up! I could've—"

"Ruby." Yang's voice dropped. "That's what the town militia is for. They're trained. And if it gets bad, one call and Jaune or Izzy or half a dozen others handle it. You are on medical leave. That means no work. I cannot stress this enough."

Ruby scowled. "I don't want to sit around! There's always something to do! We saved the world—"

Yang's hand slammed down on the armrest. Claws gouged deep furrows into the wood. Her eyes flashed slitted gold. "YES. AND THAT WAS THEN. THIS IS NOW. WE EARNED OUR REST, RUBY. THE WORLD IS SAFE."

Ruby shot to her feet. "NO IT ISN'T! It will never be safe! We learned that the hard way! There's always another battle, another threat—the work is never done! IT WILL NEVER BE DONE!"

Yang's horns began to push through. Her voice deepened, edged with smoke. "AND YOU THINK FACING IT ALONE, HALF-DEAD, WILL FIX ANYTHING? NEWS FLASH, RUBY—IT TOOK ALL OF US TO DO WHAT WE DID, AND THAT WAS WHEN WE WERE AT OUR BEST!"

"Yang! Stop! You're pregnant—you'll hurt the baby!"

Yang gripped the chair until the wood groaned. She forced breath after scalding breath until the scales receded to scattered patches, claws stayed half-extended, eyes still slitted. "Haaa… thanks."

Ruby's voice cracked. "Yang… why are you so angry? I'm doing this for you. For all of you. It's what I have to do."

Yang shook her head, bewildered and hurting. "What could possibly make you think I'd want my sister to die?"

Ruby looked away. "I… what do I have? It's all I have. It's all Mom had in the end. To be a hero…"

"Summer wouldn't have wanted this." Tears slipped down Yang's cheeks.

Ruby's voice broke. "SUMMER ABANDONED US TO BE A HERO! I saw it… in the Ever After…"

Yang stared. "…What?"

"That's what I saw in the Ponderstorm. She ran off to fight Salem alone!"

Yang exhaled slowly. "Ruby. That's not how Mom died."

"IT IS! I SAW IT!"

"The Ponderstorm lies, Ruby. It likes to screw with people. For fuck's sake, it tried to get Blake and Weiss together. Blake and Weiss."

Ruby's tears fell freely. "If I'm not a hero… what am I? What do I have left?"

Yang leaned forward. "You have us. You've always had us. This place has always been your home. But only if you let it—if you let us—be that for you."

Ruby sobbed. "I… I can't."

Yang grimaced. "Then I guess that's it." She lifted her head, tears gone, expression hard and determined. "Plan C it is."

Ruby blinked through tears. "H-huh…?"

Yang raised her voice toward the kitchen. "JAUNE! WE'RE GOING WITH PLAN C!"

Jaune reappeared in the doorway, concern etched deep. "Yang… are you sure?"

Yang nodded, mock-sorrowful. "Absolutely. She won't listen any other way."

Ruby's head whipped between them. "What is this? What's Plan C? And why does it involve Jaune?!"

Jaune took Yang's hand. "You know I love you. More than anything."

Yang squeezed back. "More than sure, my heart. You gave me your word. Arcs don't break promises." Her grin turned teasing. "Besides… don't think I haven't noticed you sneaking glances."

Jaune flushed. "They were only glances… but if this is what you want to save her? I'll do it."

Yang patted his shoulder, then smirked wider. "You're acting like you wouldn't love her just as much as you love me."

"I would. I swear."

Xia wandered back in, leading Pyrrha by the hand. "Mama…? Why were you yelling?"

Yang eased herself up and waddled over. "Nothing you need to worry about, Firelight. Just… last-minute travel arrangements." She glanced between her apprehensive husband and her very confused sister. "Your dad and Auntie Ruby are going on a little trip together."

Ruby blinked. "I am?"

Jaune scooped her up again. "We are."

He carried her upstairs to the bedroom.

Ruby blushed furiously. "W-where are you taking me?"

"The bed room," he stated. He burst in through the door and dropped her on the bed.

"ACK!" Ruby scowled. Jaune closed the door. He turned back to her.

"And we're gonna…?"

"Talk," Jaune said blandly, as he sat down next to her.

Ruby relaxed a fraction. "Oh. So we're just gonna hang out and chat like… like we used to."

"Yes…" Jaune reached out and drew her against his chest, holding her close. Ruby flushed.

"G-Geez Jaune… Do you have to be so… Clingy?"

"You haven't been hugged in a while have you?" Jaune asked. Ruby scowled.

"I… It's not important-"

"Ruby… what's this really about? Why are you so determined to get yourself killed?" He stroked her cheek. "I've been so scared for you. My best friend. Why?"

She melted against him despite herself. "Someone has to, Jaune. The world still needs heroes. And it's not like I'm doing anything else."

"That Ponderstorm really messed you up, huh?" He kissed her forehead. "I'm sorry I didn't help you more. Yang and I got so wrapped up in each other… in surviving. I'm sorry."

"Why are you apologizing? You were stuck in a fairytale hell for twenty years. Yang was a dragon. I can't even look at dragonfruit the same way."

"Even so. You were our responsibility."

Ruby's eyes filled. "Don't you think I know Summer wasn't perfect? That just means I have to be. I have to be what she couldn't."

"You saved the world, Ruby. We all did. You can let go. You can enjoy it." He kissed her—soft, then deeper.

Ruby's brain short-circuited. She kissed back, hungry, helpless. Rose genes, damn them.

Jaune murmured against her lips, "Yang wanted me to do this…"

He nibbled down her neck, hands roaming, squeezing, claiming. Ruby straddled him in the water, humming at the heat of him. "So… this is Plan C?"

He smacked her ass lightly. "Mmhm."

"EEP! And… And Yang knows?"

"Ruby," Jaune looked hurt, "Do you really think I would ever cheat on my wife?"

"B-But-How do we handle this?!" Ruby demanded. "D-Do you love us both? Marry us both? What if we have a kid or-"

"Ruby," Jaune whispered. He touched his forehead to hers. "We'll figure it out. I love you, you know?"

Ruby went bright red.

"M-Me?"

"Yes… And we can figure it out from there," he murmured. Ruby flushed.

"S-Still… Um… Are you sure-?"

Yang opened the door. She glared at Ruby intensely.

"Ruby? You're banging my husband or I'm beating you up."

Ruby flushed.

"Well… Um… If you're both fine with it-"

"More than fine," Yang growled. "Now get to it before I beat both your asses!"

She shut the door behind her. Ruby gulped. She sucked in a deep breath. She looked into Jaune's eyes.

"Then…"

One month later…

Isabel raised an eyebrow at the much more relaxed Ruby Rose sitting in front of her on the examination table. Yang, Jaune, and little Xia stood nearby, looking anxious. Despite the tension in the room, Isabel did manage a warm smile at the young savior of Remnant.

"Well… Congratulations, Ruby. You've conceived a child. You're pregnant!"

Ruby gasped, tears filled her eyes… And then she grinned.

"Oh!" She looked over at Yang and Jaune. "Plan "C'! Now I get it!"

Isabel very slowly turned to glare at Jaune and Yang, even as Xia giggled as Ruby pulled her into her lap.

"'Plan C'?"

"Just an… In-joke, Mom," Jaune explained.

"But it's definitely growing," Yang grinned.
