part 1: the new era

"Alright. Let's do this." Steven cracks his knuckles and leans over his tub, filling it with warm water. "(Name), the auras, please."

The boy held out his hand, prompting you to grunt in response as you opened the medicine cabinet and grabbed the three elegant bottles into your large hand and shut the door with the other, you catching your reflection on the medicine cabinet's mirror. You grin your usual dopey grin at yourself, showing pearly white teeth, with rather sharp, pronounced canines.

Your bottom ones in particular were long enough to peek out from your bottom lip, like small tusks, giving you a notable underbite. While they didn't bother you, you couldn't deny, you still weren't used to being the only one baring them.

"Ahem!" You flinched at the impatient grunt from the boy behind you. With a pout, you flick your bushy tail into his face, grinning smuggly as you watched him grunt and wipe at his face, spitting out residual fur that stuck to his lips and tickled his nose. "Steven doesn't have to be pushy." Steven scoffed, still rubbing the fur out of his eyes. "(Name) needs to hurry up." He mocked playfully, earning a snort and grumble from you. He snickered at this reaction, but regained his composure. "Come on, we gotta do this." He said, his voice taking on a more serious tone. You nodded and handed him the three essences. He turns to the tub and drops a sample from each bottle, with you adding in your own (color) extract with the last touch being a kiss from his finger. Your eyes glimmered as the water went pink colored the second his finger made contact with it. You've done it so many times, but it still amazed you.

He smiles lightly at this before holding out his hand to you again. "The gem, please." You nodded and reached over to grab a bubbled gem that was beside you. "Welcome back." You whispered to the gem within as you passed it to steven, him placing it into the tub.

It pops and almost instantly, the gem takes form, healing its corruption and taking the form of a rather disoriented gem, a cherry quartz, who staggers about in the bathtub, prompting you to step back, gently pulling steven back with you by the shoulders. "...hello!" steven chirped as the quartz threw her gaze around frantically. "Wh-where am I?" she asked, before directing her gaze at you both. "Who are you?" steven shrugged. "That used to be a loaded question," he began, making your lip twitch. "She didn't need to know that." You chided into his ear, to which his face falters with modest indignance. "Ahem... but now I can say with confidence that I'm Steven Universe!" He raises his hand and places it on yours, which was still holding his shoulder. "And this here is big, trusty (gem), (name)!" You nodded and smiled at the quartz in a friendly manner. "And cherry quartz in steven's bathroom!" You finished cheerfully.

The quartz eyed you both suspiciously, her gaze looking at you in particular, eyeing your horns and tail suspiciously. "Isn't that-" She starts to ask, backing up slightly until she suddenly catches herself in the mirror and the look of bewildered horror took over her face, at her own trio of horns that sprouted on her head. "What happened to me!?" You frowned, hugging steven closer as the gem started to panic, grabbing a nearby plunger and pointing it at you in confused anger. "What is this!?"

"Cherry quartz caught in diamond light!" You exclaimed in a rushed voice. "Steven heal cherry quartz! Cherry quartz better now!" Steven grunts in your grip, lifting a hand to lower the tool from his eye level. "...and that is a plunger." The cherry quartz stared at you both in uncertainty for a moment, before relaxing slightly.

After much coaxing, you finally managed to get the quartz to relax and allow you to lead her out of the bathroom. Of course, despite your unfamiliar growths and broken speech, she felt more at ease around you, seeing you were a fellow gem in the same state as her, evident by the way she held your arm in an uncertain, semi-tight grip. "Let me fill you in on what you missed." Informed steven, prompting the cherry quartz quirk an eyebrow at the boy curiously before looking up at you. "Missed?" You nodded cheerily. "Reading materials! in human language and gem glyph!" You chirped as steven handed her a pair of pamphlets, one for dealing with her new horns and the other for living in the new era. "Spanish translation forthcoming." Steven added.

"Why won't Steven let (name) drive?"

You pouted, watching as steven twirled shiny car keys on his finger, arms crossed in envy. he huffs, rolling his eyes with a small grin. "We've been over this before, (name). You're still not familiar with normal car controls." He replies simply. "And you're still too big for the driver's seat." You grunted, rolling your eyes from behind your bangs. "(Name) fits fine now!" you exclaimed indignationly, throwing the car door open. "Watch!"

"I-I wouldn't--" without waiting for him to finish his protest, pressed yourself into the small door opening, struggling a bit with your massive shoulders and bulky form squeezing against the small metal frame, shaking the vehicle slightly in the force of your straining. "(Name), I really don't think that-!" Steven's protests weren't heard over your grunts of effort as you finally managed to squeeze into the rather small car, and with effort, you managed to fully huddle yourself into the backseat, into a rather tight fetus position.

There.. was not a lot of space to move your arms.. or anything for that matter. regardless, you were inside!

You grunted in discomfort, but smiled in triumph. "S-see? (Name) fits fine!" You strained proudly. For a moment, Steven's eyes were wide in minor surprise at your feat, before he sighed in mild irritation. "Oh (name)..." he grumbles as he enters the driver's seat, before motioning to the large quartz to come in as well. "Watch your head." he advises. After the quartz situates herself into the passenger seat, Steven inserts a music tape into the player before driving off into beach city.

"Life is a little different these days," Steven starts, like he usually did. "The Diamonds have ended their reign of terror. The intergalactic war is over, and Earth is officially an independent planet." you grunt happily as you listened on, pride swelling in your chest. "We're all safe to explore our dreams. Lars opened up his own pastry shop, and it's got a real cute space gimmick goin' on." you pass by the bakery; 'spacetries', where pink boy, lars is sweeping outside the establishment. hope we go there later... "Sadie's been touring with The Suspects, promoting their new album, and Connie has been getting a head start on college prep." he continued. "She's two years away from applying, but she says it doesn't hurt to start early." he then turned into little homeworld, concluding his update on the era; "and speaking of higher education, Garnet, Amethyst, Pearl and I have been cooking up a dream of our own! Isn't that right, (Name)?"

"That's right!" you chirped cheerfully, making steven snort in amusement. The cherry quartz however, was absolutely baffled. "I have no idea what you're talking about." Steven then replies with a chuckle. "You'll learn that, and much more here at little homeschool." He parks his car and gets out of the vehicle, to which the cherry quartz follows suit. and with a gesture of his arm, he spoke up. "Here at Little Homeschool, you have a chance to rediscover yourself and learn to live on Earth if you like." he explains, quite proudly. "You can forge a new identity-"

"GUH! GRAAAH!!" He pauses as he heard your grunts and growls, along with the sounds of a car being shaken violently. He turns to the source of sound to see you struggling to get out of the vehicle, as your hips were stuck between the driver's seat and small door frame. He groaned and stomped over to you taking hold of your arms, and starting to pull.

"next time, you're riding on the roof!"

Not sure if I like how this came out.

I will rewrite once I have the appropriate mental capacity.
