Talk:Greg the Babysitter/@comment-26462356-20160705022144

When Sour Cream was young he was probably baby sat by Greg and/or Amethyst frequently, especially if Vidalia was a working mom.

So, I think this is a flashback episode were a young Sour Cream meets Opal and/or other fusions. This would explain why he was not surprised when Stevonnie split into Steven and Connie in Alone Together.
