Prologue
After the rebellion the diamonds, in there grief after losing pink, they decided to leave. But they also decided it was too dangerous to leave earth without knowing what's going on in the future. So they decided to keep a peridot there to keep watch over the rebels in case any survived the corruption beam. What they didn't know is that three gems survived.
5487 years later
"I can't believe rose is gone." said pearl "but at least she trusted us with her son. Isn't that right little Steven"said garnet with a faint smile "hey guys there's a corrupted gem in the war zone!" Said Amethyst running to the temple "You guys go ahead and I'll take Steven back to greg." Said pearl "okay hurry up" said garnet "will do" said pearl
With peridot
"I've got to tell the diamonds about this" said a slightly confused peridot. She pulled out her communicator and contacted yellow diamond."What is it peridot 7369 h4 cut gen 2? I don't have time for interruptions." Said yellow "I just saw the crystal gems and they were talking about how rose quartz gave up her physical form just to let a half breed survive." "How do we know they aren't lying?" Said YD "I don't know." Said peridot "But it's highly unlikely that they're lying. They didn't even know I was there." Said peridot. "Hmm. Good point. Take the half breed and bring it here." Said YD "Yes my diamond" said Peridot doing the diamond salute. She then immediately started following pearl. "Hmm why is she giving the half breed to a filthy human?"thought peridot "Hey pearl you here to steven back?" asked greg sigh "sadly yes" said pearl "hey you have been feeding steven right?" asked greg " yes greg we have been following your instructions on how to care for seven" said pearl "hmm that human must know how to care for the half breed i should bring him to just in case"thought peridot. After that peridot waited till what the humans call night then encased the human(greg) and the half breed(steven) in a soundproof bubble and carried them to her ship
