After eons left alone and feeling abandon Spinel came to Earth to seek revenge on the Crystal Gams. When Steven friends lost their memories, he must find the way to get them remember, while trying to stay alive from Spinel wrath. The Game of Survival of Earth rests in his hands.

Spinel wasn't hit with the rejuventor scythe. So Steven has to deal with four Crystal Gems with amnesia, the Earth slowly being poisoned, and an Cheshire Cat like enemy. (Spoilers for Steven Universe: the Movie.)

To cope with the rebellion and Blue Diamond's grief, Yellow Diamond came up with a plan to erase the grief, disobedience and insubordination in the minds of her subjects. That plan was Spinel. Five thousand years later, Spinel finally has a chance to forge a life for herself outside of Homeworld's rule, but how can she gain the trust of the very rebels she was used against?
