EVERYTIME THE OPTIONS ARE
1) call her a child and immature or act like she's a baby and you are god
2) insult something she likes
3) ignore all she said and be ironic of how much she likes time travel
I CANNOT STAND THIS ANYMORE LET ME TALK TO HER LIKE SHE'S A NORMAL PERSON
edit: okay let me get some points straight
you can be an asshole to everyone, but you can also not be an asshole, except kaya, which you can only be an asshole
her being hostile in your first interaction shouldnt mean the drifter hates her, because so is quincy, minerva, somewhat arthur and lyon (by refusing to talk to you)
kaya is an isolated teenager that knows little about caring and being cared for, a nerd who had very little friends, of course she is gonna be selfish and hostile before you gain their trust. so was quincy, but you had the option to understand him
the whole drifter and kaya relationship is just an adult not trying in the slightest to understand a troubled teenager
