Explanation: (Note, you should read my AU's info first to understand the following more!)
-Pink Diamond (AKA Rosalinda Quarta-Corazon) left spinel at the park just so she'll be able to go with her boyfriend, Greg, who had no idea she already has a kid -Meaning, Steven and Spinel are half siblings! And they never knew c': Explains how did they got along quickly when they first met each other at jollibee -Vendors, Blue Diamond and Yellow Diamond, adopted Spinel after they found her at the park in the middle of the night, sobbing -Theyre..in a different city, so Spinel doesn't know the way back to her home..and since she is still too young -Pink diamond bought the Jollibee Plushie for Spinel before leaving her behind, this is the reason why Spinel like Jollibee so much since it's the last thing she reminded of her mother
