She'd go along with his dumb goofy adventures and shoot the shit with him and feed him compliments and flash some panties here and there and get "drunk" and "confess she has weird feelings" for him one night and maybe even make out with him, even though she could care less about his general existence, and then after she's edged off of playing with Finn's emotions for long enough, he'd wake up tied to one of the spires on the Candy Kingdom with a crater in his pants and watch her brutally murder everyone he cares about and mock him for a bit before melting his face off.
Of course, she'd have to be really bored to go through with this anyway, because it's more likely she'd just instantly fuck up the planet and kill everyone, but it's highly doubtful that Dominator's gone through presumably multiple galaxies without pulling something like this a few times.
