Hey they're cousins- and actually not, if Tyrith's her dad. It's incest by technicality of no one inventing DNA testing yet and hey, cousin==marriagable. ... y'know, I'm going to stop giving Kyra ideas. It doesn't turn out well for other people.
Of course Lily needs to relax. Kaelyn does that to peole. And Tyrith is totally happy to help. ;D They need some more quality time.
