with fizz being word-of-god demi (and tbh i'd just read him that way regardless, but now they oughta make it show canon, thems the rules), thinking about whether he'd ever had sex before he met asmodeus, about how the first person he was in love with was blitzø and that clearly didn't work out, and also about him as disabled and also him as a sex object in hell, there's a lot to unpack
and then on the flipside, it seems so far as if asmodeus hasn't ever been in a romantic relationship prior to fizzarolli, and of course he does have casual sex, that's his whole job, but that's also interesting -- how does asmodeus relate to sexual attraction, when his job is about reading and reacting to others' sexual desires, and how that pertains to reading his relationship with fizzarolli as about building something more longterm that deconstructs both of the ways their public image as sexual ideals rely on what others can get from them (rather than what they feel and want)
essentially they're both in sex work or related to that work in some way, they both understand the world of desire and how to operate in that world, but their relationship to each other (romantic and sexual) is something brand new, it's something not defined by normative relationship structures (for that matter, a sin and an imp, as metaphor for all of this, is that something brand new as well?)
but yeah asmodeus is aspec too, in my mind, which i think would be just the kind of deconstruction of "the sin of lust" that would work in this kind of story. definitely somewhere on the aro side of things, fun to think about also from the ace perspective, and that's one of the (many) reasons he and fizz understand each other so well -- they're not coming at this with an innate "this is the way things are meant to be" set of ideas. there are no assumptions of who they're supposed to be when they're together (well, there are when they're in public, but once those have been challenged head-on and they come out of the closet in s2, so to speak...), so they get to build that brand new identity together in their own way
i just think that concept would be neat
