Helped by the gem using the lighthouse as a body. If I remember the end of the sneeple episode correctly, a couple articles drifted down in front of him and he was enlightened.

Enjoyable. I hope Peridot can one day manage an episode that does not end with a grudging admission. I'm also wondering how much of her knowledge and mind she kept in her extenders; I've the sense some the the loss of identity she feels with them gone is literal. And what happens when she recovers them?

Seems simple enough. You don't want cows getting into your complicated machinery. It won't end as well as Resse's Cups.

I think there was some dialog back near her Peridots first appearance. Homeworld sent the Red Eye that got blown up in an early episode. When it didn't report a Crystal Gem siting Homeworld decided the place was safe. (Why they didn't react to it not returning / stopping its reports is a good question.)

I'd been guessing something hand themed. Her weird floating finger tools. The similar floating robonoids. The hand ship. The hand interface at the kindergarden.

My guess, the final big bad will be a new Pink Diamond.

Fusions split when they run into a important personal disagreements. What if Sapphire is willing to forgive Pearl and Ruby isn't? (Or vice versa) I doubt it will happen, but it would make an awesome, if painful, episode.

When the video started, I felt the gems looked lopsided without Pearl. It makes sense, she would have resisted Greg's idea of playing instruments. Which means learning them happened in the past 15-20 years, a moment in their long lives. And makes me curious how Pearl chose the violin.

From Lion 3, talking about Earth, "Each living thing has an entirely unique experience." Humans aren't that special in that view. They're nice, but I don't think the Crystal Gems have ever called themselves "Protectors of Humans."

I've rolled up Traveler characters. Does that count?
