So these are things that I noticed in the Steve Saga that is very similar in Steven Universe

Steven Universe The Movie: The rejuvenator, can have gems go back to the way they were originally made
Steve Saga: Illusion Steve can erase memories.

Steve Saga, episode: Who is Illusion Steve
Illusion: I don't know why I'm doing this for Galaxy Steve, yet I'm going to do it.
Steven Universe, Episode: Open Book
Steven: I don't want you to just do what I want.
Fake Connie: Eh, I-you want me to not, d-do what you want. I want what you want, what you want(want times something)

This is just references.
