I've been submitting my OC, here's hoping.
Jasper, Peridot, and Diamond (carrying Lapis) have arrived at the Kindergarten, their ride coming into site as it approaches the ground.
"There it is, we will be on our way home soon." Peridot said looking up at the approaching craft.
"Wha... what happened, where am I?" Lapis said then moaned in pain, turned, and fell out of Diamond's grip.
"She woke up early. No issue though, I was prepared for this." Peridot said, doing a graceful dance and pulling two strands of rope from her gem. "Tie her up, we can't have her ruining things when we are so close to getting home. It may not be the best restraints but it's all we have without our ship."
"Please no, don't!" Lapis cried in fear as she scrambled onto all fours. Diamond grabbed the rope from Peridot and slowly approached her.
"Don't make this hard on yourself." Diamond said, pushing her down. He grabbed her wrists and bound them behind her back, then bound her ankles together. "Count yourself lucky, you'll be home soon. Though no promises on what happens when you get there." He picked her up as the landing craft arrived. A bright light beam came as the Crystal Gems came to on the warp pad, stopping across from him. "Peridot, Jasper get in and leave them to me." He said as he handed Lapis to Jasper. He drew his two katanas from his wrists. "I'm going home, I have been here too long."
"You don't know what you are doing." Garnet said stepping forward.
"I know exactly what I am doing. You really don't recognize me?" He shook his shoulders, his black body armor now covering him.
"Don't do th-!" Garnet started, but was cut short as Diamond thrust a blade through her. She fell off his sword trying to remain intact, but then in a cloud of dust was in her gems, Sapphire and Ruby split.
"You... you just... I mean how could you..?" Pearl breathed.
"What? Don't like what happens when you abandon those who trusted you?" Diamond asked, turning to get in the craft.
"We can't just let you leave here."
"Try and stop me, go ahead."
"Why are you doing this?"
"There is someone waiting for me, and I will not keep her waiting any longer. Even if I have to cut you all down." He walked into the craft, closing the hatch behind him. "Let's get out of here." The craft took them to a large ship where Lapis was unbound and thrown into a brig cell as the others were lead to their quarters.
