I still think it's amazing that not only were Ruby and Sapphire obviously flirting in 'Hit the Diamond', but Lapis outright said it! She confirmed it! It's a a great small step for more LGBT representation in children's media. To older fans, they obviously know Ruby and Sapphire are in a relationship. To kids, it may not be so obvious. Sure, they've hugged and kissed and held hands, but most heterosexual couples in media actively kiss on the lips if they're "a thing." TV's not quite there yet, but I feel SU is headed in that direction. If the show is around long enough, perhaps it could actually happen. There has definitely been a significant amount of progress made since the 'What Was Missing' episode of Adventure Time, so I think CN is headed on the right track to proper representation!
