Secret Team airs tomorrow. The preview shows Steven and Amethyst as they are about to cause Pearl to drop a bubble containing gem shards; Amethyst has said Garnet will be mad at Pearl having the bubble, and identifies it as one of Rose Quartz’s (which you can see is distinctively pink, just as Amethyst’s are purple and Pearl’s are white).
This appears to be an episode that will show us a bit more about the temple the Crystal Gems inhabit. Pearl is in her room with the bubble, so when she drops the gem shards they will probably be washed away into the waterfall; a search through the areas the waterfall leads to will probably ensue, and that just wouldn’t be fun if it simply led to Amethyst’s room. They’ll most likely plan for Steven to be the one to re-bubble it, so it will look like Rose’s bubble. We’ll probably also get a little bit more exposition about Rose or the backstory since Pearl will certainly be asked what she was doing with that bubble.
However, a fun thing to watch out for: Garnet will probably find out about their secret team in the end. And if Mr. Burnett wasn’t just being silly… We might see her bury Pearl and Amethyst at the end of the episode, until they learn their lesson. 🙂
