Rewatching that part of Alone Together and... Yeah, I don't see it with Kevin.

Seriously, with how everyone talks about Kevin and how he seemingly sexually harassed them or something, you'd think he tried to pin Stevonnie to a wall or literally touched or grabbed them, or would've tried to ask if they were gonna do anything after the dance. But after randomly rewatching that episode, he was literally just talking smugly to someone he found pretty, and the "nagging" part lasted... A whole 30 seconds? Like yeah, sucks for two kids, but literally all that happened was at most some low tier flirting during a public dance, the way Steven overreacted to future appearances feels so off to me, I'm aware it's supposed to be some allegory, but it never felt like a did a good job imo.
