I think the secret is Amethyst finds an old friend (a gem hiding in the kindergarten for years), Garnet was involved in building the kindergarten, Peridot is trying to reactivate it and the gems learn about her past and Yellow Diamond (or some other gem, yes if we are going to see Yellow Diamomd she'll most likely be on Peri's screen as an image or memory before we actually see her) or a little memory (like the pre-Warp Tour time frame maybe hearing about the mission of reactivating the kindergarten) is on her finger screen.



If Peridot can project images on that thing she's probably capable of doing video chat or just projecting memories.
