A/N:

I lost connection while adjusting the document for FFN. Pain. All the pain... Now I have to make these notes again!
Anyway, as I said originally before FFN went down on me: GU Gaiden is a group of side stories (hence the name) to Golden Universe. They take place any time after the main story, and I will be avoiding spoilers where I can, but what can I say, Yellow ends up with Greg, pretty self-explanatory if it's a momswap. So, any time after the main story, featuring either Yellow and Greg, or Steven.

Now then, sit back, read, relax, and most importantly, ENJOY!

"So if you weren't around in Dad's story of Mom and Pearl coming to Earth, when did you two get here?" The young hybrid asked, brushing his messy caramel hair from his golden eyes.

The Jasper exchanged looks with the Era 2 peridot beside her, the peridot tapping her chin with the floating digits of her limb enhancers. "Ehm…" They groaned in unison.

"Oh, please." Pearl started, walking up from behind Steven and sitting down next to him. "Why don't you tell him how you two managed to crash your ship on this planet as well?"

"Nyeh… Fine!" Peri snapped. "But you have to fill in the holes." She said, pointing at the pearl's gem.

"Gladly." She responded with a smirk. As Pearl attempted to tame Steven's wild hair, she started. "Your mother and I had been on Earth for several years. She and your father stayed close, but I did as well."

Pearl watched from a distance as her Diamond and that human fraternized. She could still hardly believe how much her Diamond had changed over the years. Once, she cursed this planet's name. Now, she dedicated herself to saving it, for the human who had shown her so much. But instead of the hard work she normally did to accomplish that goal, she was wasting her day away with him. Was Pearl jealous? Well of course, a little boy who had only known her Diamond for a few years was taking her away from the loyal pearl who had stayed by her side for millennia. But she had to admit, it was nice to see her Diamond enjoy herself. Something she hadn't seen since…

"The facial hair does you justice."

Pearl's head perked up as she heard her Diamond speak.

"Oh yeah?"

Yellow's hand began rubbing Greg's now-fuzzy chin, her usual harsh eyes gone soft as a smile graced her face. "Of course."

Pearl wanted to gag, but all was interrupted by the boom of what could only be a gem ship exiting gravity drive. Both gems rose to their feet, wide-eyed as they watched the green ship which headed their way.

"D-do you think they came for us?" Pearl squeaked, nervously looking to her Diamond.

"We never got a message out. There's no way they could know." Yellow commented, focused on the looming threat.

"Earth, it's been too long." Jasper stated, watching as the planet's surface drew nearer.

"Uh-huh." Peridot drawled as she kept focus on piloting. "If you want to share more war stories, why don't you pick a gem that cares?"

A large hand gripped the back of the pilot's seat. "You wanna repeat that?"

The peridot shrunk in her seat. "N-no…"

The ship jolted.

"What was that?" The orange gem exclaimed.

Smoke emanated from the gloved fingertips of the giant who had used her gem powers to repel the threat. Her gem held a faint glow, ready to call upon its might at any moment while her eyes remained focused on the invaders in the sky.

Meanwhile, Greg and Pearl stayed hidden behind a nearby tree. The young man's head peeked out from their cover, concern heavy on his features.

Another blast rocked the ship and Peridot attempted to adjust, but another was quick to throw it off once more, this time sending sirens blaring.

As soon as she regained balance, Jasper shot towards the technician, grabbing her arm and roughly spinning her around. Her eyes bore into the timid gem in a terrifying display. "What was that?"

"Erm…" Peridot turned back to the monitors, now free from Jasper's grasp. "It seems we're-" Another blast jolted the gems. "Taking major damage from a ground-based source."

"Ground-based?" Jasper rushed to see what was visible outside the ship, keeping her footing best she could as she made the journey. What she saw made the quartz warrior pale. "Oh."

Electricity crackled around Yellow Diamond's form. Sending one more blast towards the gem ship sent it falling to the ground.

Greg attempted to run from cover, but found himself stopped by Yellow's pearl, who kept a tight grip around his wrist. "But…"

"They'll be fine." She assured him, noting how his gaze drifted to the smoke which billowed from the nearby wreck. "After all, we were."

They watched as Yellow made her way towards the crash site.

Jasper held a large sheet of metal on her back, doing her job by protecting the peridot she was assigned to escort. She growled, pushing back against the weight to free the two of them from this prison. After all her effort, clawing and climbing her way to the surface, the first sign of light was a great relief. Climbing on top of the rubble herself, she then pulled the technician out as well. But a shadow grew over their crater.

The two gems looked over their shoulders, and were met with the sight of a Diamond standing over them with her arms crossed. Jasper and Peridot spun around, quickly bringing their arms up in the proper salute.

"Who told you to come here?" She asked, getting right to the point by avoiding all pleasantries before they could begin. "This planet is restricted."

"You did?" Peridot meekly responded. "A-at least the notice from my supervisor said you had."

"What?"

"Yellow!"

Anger gave way to concern as the Diamond's attention shifted to the human and pearl running up to her. "You shouldn't be here." She said, ignoring the saluting gems who exchanged glances in the wreckage below.

Before Greg could open his mouth to explain, Pearl pushed in front, words pouring from her mouth. "I'm sorry, My Diamond. I tried to hold him back, but he wouldn't listen!"

Greg pushed back in front of Pearl to have his say. "Yellow, please let me explain." He pleaded. Upon an approving nod from the giant gem, he continued. "I was worried. About what you these gems and what you might do to them," he said, gesturing toward the two who had since dropped their salutes. "About you."

Silence permeated the air. During that time, the human and gem matriarch seemed to have a silent exchange which none of the onlooking gems could understand. The first sound which broke was the defeated sight of the great gem. She looked down to the gems she had sent crashing to the earth. "You will not contact Homeworld, you will not flee this planet. Is that clear?"

"Yes, My Diamond." The gems said in unison.

She nodded, and proceeded to shift down, joining the human. "This way."

"So Mom threatened you into staying?"

"Nah." Jasper waved off. "That was Pearl."

At the recognition, Pearl made a devilish smirk. "As I recall, Peridot was ready to dissipate herself after that."

"I was not!" The green gem shouted, though the deep flush of her face betrayed it all.

They all laughed. And as the gems began to argue about what happened back then, Steven's eyes drifted over the interior of what he called home, the reconstructed ship Jasper and Peridot arrived in. But it was less of a ship now and more of a normal house you could find on Earth, plus Homeworld's technology of course. As he thought back on all of the stories his dad and the gems told him, his heart began to ache. No, it wasn't his heart. He reached a hand up to the source of the pain. His gem, her diamond.
