It is a thing to be sad about. Lesbians. They're the most sad thing you can imagine.
Lillie could never have a happy family. Moon's family line ends with her. Her mother will never see a grandchild. Lusamine will never get a chance to redeem herself, by properly raising her grandchildren instead. Hau and Gladion cucked by nothing. I say nothing because being a lesbian is just pointless. Everything you can do with a women, you can do with a man. So this entire thing is just a sad, pointless mistake that makes everyone's lives sadder
