They both hate the fact that they have autism, although i believe Emilly hates it more because she considers herself weird because of her autism and because of her self loathing… sometimes she daydreams what it would be like if she didn’t had autism… as for Oliver, even hating it, he tries to deal with it and tries to mask his autism in order to look “normal”.
Every time Phantasmo tries to charm Emilly (not because he likes her or anything, it’s because he wants to use her as another experiment haha!) she just rolls her eyes and keep doing her chores (whenever she’s working or simply going out for shopping groceries). But… she quite can’t resist him when he cross dresses as “Vanessa” (yes, i headcanon that Phantasmo likes to cross dress himself, why? Because i said so 💅😌💅) and just… sometimes let him take her on a veryyyy platonic date (but not because he likes her guys, nope. Totallyyyy not… he only finds her… “interesting”… although she doesn’t know how someone could find her “interesting”, she appreciates the… without second intentions compliment)
Phantasmo doesn’t even have to try to… “charm” Oliver too because he’s already head over heels for him, Oliver is like a little puppy who follows every order Phantasmo gives him… (and that may or may not have got him killed a few times now)
