Alright, so remember in Hit the Diamond, where the Crystal Gems were coming to the conclusion that Ruby and Sapphire did not have it together for the baseball game? The gems didn’t seem to know what was going on until Lapis clarified
“What are they doing?”
Then later, while Ruby and Sapphire continue to be unbearably adorable (but VERY UNHELPFUL) we get another shot of the Crystal Gems (and Lapis) reacting to their antics
Lapis gives them a thumbs up. Nobody else is half as amused.
