Hit the Diamond
Doc Ruby comes out of the ship after the rest of the squad, She is persuaded by Steven to play baseball, as he says if they win, they can check the barn, but if they lose, they have to leave forever, as the gems believe that Peridot is the one they’re looking for. When they lose the match, the Gems accidentally reveal that they are not humans and the Rubies fuse in order to attack.
