i was actually trying to figure this out in a call last night, because the idea of percy in a setting that isn't the treacher sea is an interesting scenario to process, let alone actualize. my freak, operating free of the constraints of our beloved ttrpg that i kind of use as a way to macrodose all of my personality disorder symptoms and latent gender dysphoria by proxy of playing an irritating and deceptive twink who desperately is clawing at the mere concept of belonging? egads! what the fuck!

anyway, in my heart of hearts i know that (a modern, living in 2020s) percy would have two main forms of social interaction with the outside world:
1: bookblr/"dark academia" type blogging. he canonically enjoys YA fiction, so like, yeah, a 22 year old curating an aesthetic blog that also makes mood/stimboard posts with quotes from like, percy jackson or some shit checks out. does he like twilight? yeah, probably. i actually don't know what YA fiction is relevant anymore.
2: grindr. consulted with a friend on this one like, last week, actually! percy uses it with the intention of "no strings attached" style encounters, but winds up falling for someone and then spends the next six to eight months in some kind of quiet favorite person hell where he loops Flashdance...What a Feeling - Radiot Edit while sitting in his shower fully clothed. you know how it is.
