I saw a crazy theory, I will try to move the whole thing here. link http://aphot-nuit.tumblr.com/post/129837560260/so-did-anyone-else-notice-that-peridot-keeps

So did anyone else notice that Peridot keeps referring to something called “The Cluster”? There’s a reason for that.

None of the Cluster Gems we’ve seen so far are The Cluster itself.

Every time Peridot mentions the fusion experiments, it’s always been in reference to something called The Cluster. Not the cluster gems. The Cluster. Peridot also keeps saying that this thing is going to kill everything. She says in “Friend Ship” that Earth has an expiration date. She said in “Catch and Release” that The Cluster was going to destroy everything, going so far to say that she and everyone else would be shattered. Why would Peridot be afraid of the monsters that were easily poofed by Connie, Steven, and Garnet? Because those things aren’t what she’s talking about.

This thing? Nope.

This guy? Nu-uh.

Not even this guy is the actual Cluster.

But, take note of the fact that Peridot also mentions that The Cluster will hatch. Not emerge. Hatch. Notice that an upcoming episode is called, “When it Rains.” The plot? “Steven helps a friend who’s afraid of thunderstorms.” I’m making a lot of assumptions here, but what if that friend is Peridot? And what if the reason she’s afraid of thunderstorms is because-

-THIS thing contains more than just a synthetic thunderstorm. After all, what’s inside a geode? A massive cluster of rocks and gems. The writers did say Steven’s healing powers would have worked on the Geode, had Greg not messed them up, but every single time Steven has used his healing powers, it was on a living thing. First on Connie’s eyes, then Lapis’ Gem, then Greg’s leg, and his attempt at healing the Geode. What if the healing powers only work on living things, which was why it didn’t repair the Homeworld Warp? What I’m getting at here is, what if the reason Peridot fears thunderstorms, is because the Geode has more than just a storm inside of it. The storm just means the geode is cracking. Hatching. This is not a Geode at all. It’s an egg.

An egg for the Cluster.
