I honestly feel like Riverdale's writing staff were trying to write a horrible show
highlights of the Pilot script (which didn't make it into the final episode) included
Kevin (who is I assume 15 since he's 15 in the comics) trying to use Grindr to hook up with adult men, then deciding to go "watch gay porn with Betty" when it didn't work out
and apparently there was a leak early on that implied Archie killed somebody, which also never happened
interestingly enough there was supposedly a scrapped Storyline where Kevin was closeted because his dad was Homophobic and THAT'S why his Dynamic with Veronica was semi-romantic in the final show, they scrapped the closet storyline but didn't re-write any of the other elements of said storyline
