I think this episode reinforces my theorty that at one point gems were experimenting on humans to see what kind of results could be acheived. The dark figures seen on the temple walls in Serious Stephen are not Rose controlled plants, they're humans. Humans rose up in defiance of gem masters, and Crystal Gems aided them in banishing other gems from the Earth.

Stephen is the first successful result of a Gem and Human union. Stevonnie is the first successful result of a humangem and human fusion.

Gems were using humans to try and breed slaves or super-warriors. My theory.
