I love finding two characters who could be the only members of the world's most specific support group.
"I'm 17 but I'm also sorta kinda several centuries old and need to emotionally deal with my immortal mass-murderer other-self while figuring out military command" welcome, Jedao 2, Tisarwat, please pull up a chair.
"I'm a lesbian who's good at math with a dead person living in my head, and I need to sort out my war trauma as well as the emotional fallout of growing up in a marginalized culture I've been taught to look down on and my parents being used as pawns to manipulate me" Cheris, I'd like you to meet a woman named Baru Cormorant. I don't think you'll necessarily like each other but there's at least an 18% chance you'll have sex anyway.
