Ah yes, 'Hit the Diamond'. Steven attempts to save Peridot by tricking Homeworld gems into playing a simple human sport. I guess the rubies thought they would win and could avoid a conflict. Even after fusing, it seemed to be more of an intimidation tactic rather than a battle tactic. They were totally willing to talk things out and were only after information, not a fight. I wonder if the rubies will return to Earth if they don't find Jasper?
