Are you trying to tell me, that brainwashed women and their sociopathic tormentors can't be in love? I thought this was 2020! 
And yeah, I don't even think Kith really feels like an adult yet, she just looks like one to most of the world and uses it to her advantage. I kind of think that's how a lot of people feel--though in the case of her Sylvari side, it is true haha.
P.S. *raising finger to the sky* AND ANOTHER THING, Kith wasn't into the torture or punishments. She came to believe she needed and deserved them, but she didn't like or get off on them. She liked the post-pain cuddles from the powerful, lovely priestess afterward
and was also feeling pretty lonely with almost everyone she loved DEAD.
P.S.S. Fun fact: at the time of HC, Kithran is 28 (baby Sylvari), the same age as Tara was when she passed away :3 though her bday is coming up, as it is in KCandK. Sort of. 1st of Dhenns
so still a few months away. Plenty of time to find that perfect gift! Better get her something nice!
