Deep in the annals of the horrid facility that was the Human Zoo, Blue Diamond was standing in the center of a peculiar pink room. Blue Diamond was one of the four members of the Diamond Authority, the awful rulers of the Gem Homeworld and the Crystal Gems' arch-enemy. Floating above the colossal Gem were hundreds upon thousands of much smaller Gems, neatly wrapped inside pretty pink bubbles, and safe from anyone who wished to bring harm to them. They were Pink Diamond's Gems, and all that Blue Diamond had left to remember her late colleague by. As her name implied, Pink Diamond was one of the members of the Diamond Authority…well, she was a member, for she was shattered by Steven Universe's mother, Rose Quartz, when she waged war against the horrible ruler millenniums ago. To Blue Diamond, however, she was more than a colleague…she was her friend, her family. And she's been taken away from her family for so long that Blue Diamond just didn't know how she could go on without her.
She stared at the little Gems floating above her, and tears started to run down her cheeks once again. She buried her heads in her arms and fell to the ground. Unable to hold her emotions in anymore, she started to bawl uncontrollably, which angered the other colossal Gem that was next to her in the room. The other Gem grabbed Blue Diamond from the floor and set her back on her feet, then raised her dainty-looking yet horrifically massive yellow hand, and struck the Diamond across her face. She was Yellow Diamond, yet another member of the Diamond Authority, and Blue Diamond's far sterner, far more abrasive counterpart. While she didn't like showing it, Yellow Diamond missed Pink Diamond, too. But she knew that she couldn't mourn her forever, and that her and her blue opposite and equal still had a galaxy-wide empire to rule. The evil yellow Gem held Blue by her shoulders and gave her a mean, menacing look.
"This is no way for a Diamond to live, Blue," Yellow Diamond said. "You have to move on someday."
"I-I… I don't think I can," Blue Diamond said. "I don't want to forget her."
"I know you don't want to, but you must. It's been millennia since that Rose Quartz shattered her, Blue! Whether you like it or not, she… S-She…"
Yellow Diamond let Blue go, and looked at the bubbled Gems floating above their heads.
"She isn't coming back," Yellow Diamond said, "not now, not ever."
The horrible Diamond raised her stark yellow hand again, and every one of the bubbled Gems started to circle around the room.
"I understand these Gems were hers, Blue," Yellow Diamond said, "but that doesn't mean anything anymore. Sooner or later you must decide what to do with them…or I will."
The sad, droopy look in Blue Diamond's face slowly but surely turned to a strange mixture of fear and anger.
"What will you do?" Blue Diamond asked.
Yellow Diamond averted her gaze to two little Gems standing in a corner next to each other. They were two frail-looking Pearls—one was a serene and lovely blue, while the other was a disgusting and ghastly yellow. The two were watching their masters the entire time, wholly indifferent to their heated debacle.
"Pearl?" Yellow Diamond said.
"Yes, my Diamond?" the ugly yellow Pearl asked.
"Get out—I wish to settle this matter with Blue here personally…"
The yellow Pearl raised an eyebrow, wondering what he master meant by "settling the matter personally", but know that is wasn't any of her business, and with a quick formation of a diamond shape with her hands and a polite bow, she left the room without a word. Blue Diamond gritted her teeth at her yellow colleague, who was still making the bubbled Gems circle all around the room. She then looked down at her own Pearl, and gave her a small smirk.
"Pearl?" Blue Diamond said.
"My Diamond…?" the beautiful blue Pearl asked.
"Leave us alone. Yellow is correct; this is a matter that needs to be handled…personally."
The blue Pearl did the same diamond formation with her hands, along with an adorable little curtsy to her master, and left the room without any trouble. And so, the two giant Gems were left alone inside the massive pink chamber, completely at odds and unable to come to an agreement with what to do about the bubbled Gems.
"I should've known a sappy little musical number wouldn't have done anything," Yellow Diamond said, "but that's a mistake I don't intend to make again."
"I know what you want to do with them, Yellow," Blue Diamond said, "but you're mistaken if you think I'm just going to let you…s-shatter them all like they're nothing!"
"They are nothing! Just look at them… A bunch of hideous, insignificant little specks kept safe and sound in bubbles for who knows how long, contributing nothing to our cause."
"I told you already, they were…they were Pink's! Don't you understand? …They're all we've got left of her."
Yellow Diamond balled her hand in a fist, and the bubbled Gems floating around the room stopped and collected together into a humongous pink sphere. Blue Diamonds eyes widened, but she failed to react in time. Yellow Diamond made a swift punching motion with her hand, and all the pink sphere went hurdling at her blue counterpart at a terrifying speed, colliding into her and sending her crashing into a jagged pink pillar. The sphere broke apart into thousands of bubbled Gems once again, and with another little gesture of her hand, Yellow Diamond sent them back into their perpetual circling limbo. Blue Diamond effortlessly swept the debris of the pillar off her body, and got up like it was nothing…except she started to tear up yet again.
"Yes, that is true… But you must look at the reality of this situation, Blue," Yellow Diamond said. "These Gems? Those…humans in that glorified pigpen? All those useless Amethysts and Jaspers? This entire structure? They're in the way… All of them."
Blue Diamond scowled.
"What do you mean by that?" Blue Diamond asked.
"I mean we must do away with these meaningless things, Blue!" Yellow exclaimed. "Those bumbling Amethysts and Jaspers endlessly shirking they're duties and playing around, accomplishing nothing of worth, stressing your own Agate out of her mind… Those ugly, fleshy…things, living in that paradise-like hovel, wasting our own resources to pamper them and cater to their every wish… The very base we're in right now! Something that we could've converted into a weapon centuries ago… Something that we could've used to conquer even more planets… And these."
The bubbled Gems stopped circling the room once more.
"These ugly little Gems, stuck in this room, floating around in these bubbles for thousands of years. They could've all been outstanding warriors. With they're help, we could've conquered so many planets! …But no. Here they are, stuck in bubbles forever…because of you."
Blue Diamond's lips quivered, and instantly she was down on the floor again, bawling uncontrollably, and still unable to come to terms with the fact her friend was gone. Yellow Diamond rubbed her temples and rose her hand up, and Gems went back up to the ceiling, and with one last swish of her ugly yellow arm, the beautiful rocks were left suspended in the air once again. Yellow grabbed Blue and set her upright once more, but this time didn't bother to slap her, knowing that it wouldn't solve a single thing. Instead, she gave the sad, sad Diamond a hug.
"I… I miss Pink, too, Blue. Really I do," Yellow Diamond said, "but we cannot mourn her forever. Look at those Gems up there. They're living a fate worse than death…and it's all because you can't let it go. …Which is why I'm going to give you a choice," Yellow Diamond said.
"…What kind of choice?" Blue Diamond asked.
"…Have all the Amethysts and Jaspers shattered, un-bubble these Gems so they can be outfitted and put back into the army, and dispose of the humans so that the zoo can be destroyed and its scraps can be used in the creation of bigger, better, more beneficial structures and weapons for us our people."
Blue's eyed widened, and she pushed Yellow Diamond off of her, and covered her mouth with her hands, unable to believe what her colleague just said.
"A-And if I don't?"
Yellow Diamond scowled.
"…Then I'll request our Diamond to do it instead."
Blue Diamond let out a loud gasp as her eyes widened once again. Her pupils shrunk as she looked at the insignia of the Diamonds that was situated above the exit door: It was a light teal triangle situated inside a large green circle. In the triangle were three smaller, upside-down triangles, representing the members of the Diamond Authority. Side-by-side there was a yellow triangle and a blue triangle, obviously referring to Blue and Yellow Diamond…but that wasn't what Blue Diamond was staring at intensely. She was starting at the triangle on top of the blue and yellow ones. It was a triangle that was completely white in color, free of blemishes, smudges, or abnormalities or any kind. Of course, if was just a part of a harmless symbol…but to Blue Diamond, it was something that instilled a fear like no other inside her.
"Like I said, I came here to bring you back to reality, Blue," Yellow Diamond said. "And if that wasn't a reality check…then I really don't know what else to tell you."
Yellow Diamond did another small gesture with her hands, and in an instant the door was open.
"Where are you going?" Blue asked.
"Back to my ship," Yellow said. "Unlike you, I've got an empire to rule."
Yellow Diamond walked out the room, her hideous yellow Pearl scurrying behind her. The pretty blue Pearl entered the room again, and noticed her Diamond was on the floor once more, bawling her eyes out.
"…I heard everything, my Diamond," the blue Pearl said.
"…Is that so?" Blue Diamond asked, chuckling. "Then tell me, Pearl… What do you suggest I do?"
"…I do not know, my Diamond…I am nothing but a simple Pearl."
Blue Diamond smiled at her adorable little Pearl, then fully collapsed on the floor, and broke into tears once again, and cried and cried for what seemed like days…
