Now it makes sense why Steven needs to learn to fuse and the revelation of the whole lunar sea spire test, he needs to be at his best if the gems from the homeworld arrive in earth.

But it seems like Peridot was quite scared at the thought of the warp pad being "compromised" maybe the Gems from the homeworld don't travel to earth cause they're afraid of getting corrupted.
