Personally, I'm excited about the level of tension between Peridot and Lapus they established just as the episode ended.
I'm guessing everyone else got the subtle Aladdin reference, especially in the title. The scene with Jasmine and Aladdin on the flying carpet, of course. Music even seemed to hint at it.
Also, surprising that it's revealed that Lapus pretty much has no love for the Homeworld Gems or the Rebel Gems and becomes a gem without a planet. The Homeworld Gems didn't seem to care that they broke her down to her base form and used her as a magic mirror, the Rebel Gems just not knowing what it exactly was. Starting to think the reason Garnet wanted Steve to leave the mirror alone that badly was because she saw into the future enough to see what would go down.
Hope this means Lapus is a semi-regular on the show from now on.
