We have been learning so much about gem history lately, and specifically, about Rose Quartz. The Crystal Gems always talked about how she valued all life, both on Earth, and on Homeworld. And yet, it was later revealed that she'd kept a secret Lion, bubbled one of her friends, and even shattered a Diamond. At her core, Rose Quartz was a war hero, and war is never pretty. Perhaps the wise and caring Rose Quartz has even more dark history than even the Crystal Gems know.
