Giant Spider Lesbian lore time:
He still uses he/him pronouns because he honestly just feels more comfortable using them, but the whole incident of turning into a giant spider lady threw his gender all out of whack. He very vaguely identifies as a lesbian, but he's got a lot of jelly in his jam that he needs to unpack before he can make any conclusive statements about it.
Chris/Kris (the giant spider lesbian in question) is roughly based off of the tarantulas that my grandmother used to take care of, rather than the "traditional" spiky armored type.
Because... I mean... Fluffy spiders are better for cuddling.
