To LordAlex07998, I would kindly like to say "no" to your request. The Diamonds are already not my favorite characters to write about.
Spinel had finished watering her monkshood flowers near the back of her flower shop until she heard loud cooing from her pet doves. Both their heads swerved to face the clock that read 2:30 pm. She sighed. Golly, work went by pretty quickly than she had expected.
She made sure the window was open in case if her pet doves wanted to go outside and checked their food and water were full.
"Be good, Micah, Coralie," Spinel gently told them.
The duo of bleeding heart doves cooed at her before fluttering into their medium sized cage, and gazed at her as she gathered up her stuff and left the flower shop. She locked the door behind her.
She still couldn't believe it when she heard news about Yellow destroying her garden. All those months of work for nothing. Right. Like she'll forgive them for that. But she forced herself to let it go, it had been over 2 years since that happened. It didn't matter anymore...
Spinel was walking close to the beach house, but when she turned the corner, she heard cheering and shouting. Confusion mixed with shock appeared as Spinel saw the many Gems playing volleyball. From Snowflake, Ocean, Biggs, Angel Aura, Lace Amethyst, Zebra, Crazy Lace Agate, and Blue Lace Agate.
And she too noticed her lover, Pearl, talking to Steven and... someone else. Settling her stuff down on a rock, Spinel ran over to investigate.
"Hey! Steven! Pearl!" She called out to them as she came close until she stood beside Pearl, "What's going on?"
The other pink Pearl smiled politely, "Hello there!"
Spinel blinked, "Wait... you're the Pearl White used to control, but became free, right?"
"Right! And I came here to get this fixed," The Pearl pointed to her cracked eye.
"Oh jeez," Spinel sympathized, "You poor thing."
"I know, but my spit didn't work for some reason," Steven explained, "There's gotta be a way to help Pearl-" He paused and looked between Pearl and the other Pearl, "Ah shoot, there's two Pearls here. We need a nickname."
"Well-" Spinel said before sensing a ball incoming and she instantly punched it away before going right back to her previous position, "How about... Petunia?"
The pink Pearl giggled, "Petunia? That's so funny! Oh Spinel, you were truly blessed to have Pink as your Diamond, you really took inspiration from her."
Spinel frowned a bit in discomfort, Pearl patting her shoulder as Steven chuckled a bit, "Yeeeeaaah, enough about Pink! How about we fix the crack instead? Hey Pearl, know how we can fix her if my spit can't?"
During his sentence, Spinel watched Angel Aura get thrown and crash into the sand.
Pearl thought for a moment, "Well, if a Pearl was damaged, they were usually taken to the Reef."
"Yes!" Petunia nodded, "That's exactly what Pink would do!"
Steven flinched at the name.
"Well, Spinel and I were her servants."
"Me too! We were very close."
Spinel had to keep biting her lip to prevent herself from scowling at the naive Pearl. She didn't understand why Petunia was so obsessed talking about Pink. But like Steven, she wanted to help Petunia with her cracked eye, and that's what should matter right now.
At The Reef
"Here we are," Pearl said as they arrived.
"This is the Reef?" Steven asked, looking around, "This is where we'll get the help Petunia needs?"
The pink Pearl nodded, "Yep! It also serves as a luxury boutique and a center for refurbishment and repair."
"Repair, yes!" Steven walked over to a pedestal, "That's exactly what we're looking for."
Spinel gazed around the facility, "Gee, I've never been to this place before. But then again, I'm not a Pearl."
Pearl shrugged, and the three Gems stood behind Steven as he placed his hand on the pedestal and a voice came up, "Welcome, Pink Diamond."
"N-No," Steven forced his anger down, "Call me Steven Universe."
"Welcome, Steven Universe. I am Shell, your guide to the Reef."
"Hey Shell. One of our friends, Petunia, has a crack on her eye and we're hoping you can fix it."
"Understood. Please follow the illuminated path to the Care Center."
On the floor, were multiple lights that looked like they were making paths into multiple rooms. One of them lit up, just as Shell described.
"You really didn't have to come all the way out here for such a trivial thing," said Petunia.
Steven turned his head to face her, "It's not trivial. We're doing this to help you get rid of the damage. It's what we do for all Gems."
"Here Petunia," Pearl smiled in a jeering manner, "I'll hold your hand for you."
Spinel frowned a bit when she saw that.
They finally reached the Care Center. Both Pearl and Spinel were equally sour with Petunia, albeit for different reasons.
"Welcome to the Care Center," said Shell, "We have everything here to update or repair any Pearl."
Petunia stepped over to the blue platform, as Shell scanned her, "Scanning in progress."
"So," The pink Pearl inquired as the blue ring surrounding her dissipated, "How do I look?"
"I'm sorry. There's nothing I can do."
Petunia's hope crumbled.
Steven recoiled slightly in shock, "B-But you said you can repair any Pearl!"
"Her physical form shows damage, but her pearl is perfectly fine. This injury must have been so impactful that it continues to manifest despite the fact that her pearl has been repaired."
"W-What does she mean by that?" Steven asked, hoping anyone would answer.
Spinel tried to think, "Maybe it's more of a... emotional kind of damage?"
"That's absurd!" Petunia turned around to face them with a smile on her face, "I am fine."
Her crack worsened.
The pink Gem immediately felt bad for the Pearl, "Oh Petunia, I'm so sorry we couldn't help you."
"How could White be so careless?" Pearl growled in anger.
Petunia giggled, "Oh, no, Pearl. You've got it all wrong. Pink did this!"
In that moment, Pearl and Spinel felt their anger flare as they approached the pink Pearl, the former asking "What did you say...?"
Steven was unable to stop them while Petunia casually explained, "It's a funny story, really. Once, Pink got tired of asking Yellow and Blue for her own colony, so she went straight to White. Of course, White told her she wasn't fit to run one, and well, that set her off."
"Set her off?" Pearl asked agitated, "What are you talking about?"
Spinel bit her lip.
"You remember how she was with her destructive powers, throwing tantrums left and right. She had a scream that could crack the walls. She didn't mean to hurt me," Petunia said, laughing a bit, "I just happened to be standing too close to her that time and-"
Steven clasped his head, "S-Stop it! That doesn't matter anymore!"
But they didn't.
"Destructive powers? Pink didn't have destructive powers, she was a healer! She didn't throw tantrums; she kept her feelings secret!" Pearl argued.
"P-Pearl," Spinel stood in front of her in a attempt to prevent any real fight, "D-Don't be mad at her, I-I also knew about Pink's tantrums! She often told me about her problems back at the Garden, but I didn't really care much about it!"
Pearl stiffened, "You knew about it?"
"I-I didn't think it mattered until now! Pink never told me about this!"
Petunia blinked, "Oh, you remember her tantrums too? How long did Pink have you-"
"You." Spinel glared at the Pearl, "Stay out of this. Our Diamond is dead now, and we're just cleaning up her mess. Stop talking about her."
Petunia was taken aback by her statement, watching Pearl and Spinel argue about Pink keeping secrets from them again.
"SHUT UP!" Steven finally screamed, turning pink once more, "I can't STAND hearing another horrible thing she did! Especially to a innocent Gem like her! I never want to think about her ever AGAIN!"
Spinel's anger faded, "S-Steven-"
"I just wanna move on... I just want TO FIX IT!" Steven roared angrily, his voice echoed and created a shockwave that created a crater beneath him, multiple cracks running through the floor and up the walls of the facility. Petunia cowered behind Pearl and Spinel, frightened by the familiar experience she endured before being controlled by White.
Steven glared down at his reflection on the floor, gasping in horror at what he had done. The pink aura faded just as Shell's voice appeared, the room turning red.
"I am terribly sorry for the troubles these defective Pearls and Spinel have brought you. For Pearls exhibiting problems this severe, rejuvenation is required."
The hybrid's head shot up, "W-What!?"
A shell of an oyster appeared around the three Gems on the panel, clamping shut and trapping them inside. "When the process is complete, they will obey you without fail."
Steven's horror grew as he sprinted towards the shell, banging furiously on it, "NO! NO! DON'T DO IT! I BEG OF YOU! PLEASE!"
"Do not worry, Steven Universe. Your Pearls and Spinel are about to be better than new. Feel free to watch their progress on the view screen," Shell calmly replied. A screen above the shell popped up, revealing Pearl, Spinel, and Petunia. They all screamed in pain as the rejuvenation began.
Memories from what happened with Apache caught up to Steven as he slammed his body against the shell, wailing out, "STOP IT! I DON'T WANT THIS! I LOVE THEM JUST THE WAY THEY ARE!"
Inside, Spinel kept banging on the shell, hearing her son's cries of desperation, "Steven!"
"S-Spinel, I'm sorry!" yelled Pearl, "I'm sorry for what I said. I know you still want to forget her!" She then turned to Petunia, "And I'm sorry for not believing you! It looks like I'm still making excuses for her..."
With a yelp of pain, Spinel fell to her knees, Pearl and Petunia rushing to her to embrace her.
"I-I can't help being reminded of Pink!" Petunia wept, "I just can't help it! She didn't mean to hurt me!"
Spinel looked up at her, "But you were hurt! And we can't heal it!"
Petunia stared at the couple, tears welling up in her single eye, "H-How... did you two heal? You were hurt too!"
"... We had each-other," Pearl and Spinel replied, reciprocating her hug. Petunia held them tightly, a light surrounding them.
Steven kept slamming himself against the wall of the shell, not caring if his shoulder was beyond aching at this point. However, he failed to see the screen fading, but he noticed the shell cracking. He backed away as it exploded, revealing a light figure. He thought it was Peach Moonstone, but when the light faded, that wasn't the case.
The fusion had most of Peach Moonstone's features, but with another Pearl in the mix, this fusion's appearance was tweaked slightly. She was taller than Peach Moonstone, her crescent-moon-shaped hair was hot pink, wearing a golden tiara, her side bangs curled up like Petunia's. On her working peach pink eye, were several long eyelashes. As for her outfit, she now had a pale tan crop top with a rose gold sash. With her dress gone, it was changed into a long, dark, transluscent cape, decorated with an array of white stars. She now had white stockings with pink slippers.
"You fused!" Steven exclaimed, his eyes shimmering at the marvelous fusion.
The fusion, as we're going to call her Cerise Moonstone, stood proudly, her cape blowing and holding her two pairs of arms on her sides. Suddenly, the core of the Care Center illuminated crismson red.
"Warning: Unauthorized entity found within the facility. Defense protocol activated."
Multiple claws emerged from the walls around them, surrounding Cerise Moonstone, but she quickly summoned her bladed ribbon wand and sliced through them.
"We have to shut off the Reef!" Steven told her.
Cerise Moonstone nodded, gently grabbing the teen, "Then let's not waste time."
She leapt out of the room, just as the doors shut behind them. Cerise Moonstone swiftly manuvered over the lasers and was faster on her toes, being a fusion of three Gems who were known for their gracefulness. Before any of the shell walls could block their path, they slid into the exit. Steven landed when the fusion was held back by one thin tendril.
Steven, thinking fast, ran over to the pedestal and slammed his hand on it, shutting down the facility. All of its defenses shut off at once, Cerise Moonstone grabbing the loose tendril and tossing it to the side. She turned to look over to the relived Steven and smiled.
At night, Steven was drawing in the sand with a twig, until two bleeding heart doves flew onto his shoulders, cooing. He was confused for a moment, but Cerise Moonstone appeared as well.
"I'm... sorry about everything," Steven spoke, "I wasn't able to do a thing."
"But you did," Cerise Moonstone replied, eyes glimmering, "You helped them understand each-other. One knew about Pink Diamond wanted to change, but didn't understand why. Another knew why, but was afraid her loved one would stop loving her if she admitted it. And the other didn't expect Pink to change at all. Now, I get to understand everything. Now, they've finally get to have one another."
One of the doves, Micah, flew up to the fusion's shoulder. Cerise Moonstone closed her eyes and unfused into Pearl, Spinel, and Petunia. Spinel gently scritched Micah's neck with her finger as she, Pearl, and Petunia gazed up at the full moon, feeling heartedly happy.
Just as Petunia leaned on Pearl's shoulder, Spinel broke the silence, her tone humorous, "Pearl. Don't get any ideas."
Coral-ie. Mica-h.
GET IT?
...
Also, I thought the nickname 'Volleyball' was too stupid and too random, so I thought 'Petunia' would work since Spinel and Steven love flowers.
Deal with it. If you can't, well...
Hope you like the name I came up with this triple fusion. Cause I know that's not a real name for a Moonstone, but so isn't Cotton Candy Garnet or other names that several OCs have.
...
Unpopular opinion: I don't like Pink Pearl X Spinel. So don't expect any of that here. They're just friends.
