Oh look, a bandwagon!

I'm similarly of a mind that while Tybs is gonna try something that winds up handing him his ass. He has yet to be effectual at all. He's gotten by as far as he has based solely on his privilege, not an any ability on his part. I'm honestly not sure that he's going to try something out-and-out
gross with Jill, though there's some clear foreshadowing that he'll do.. something. Tybalt is a smarmy, self-important asshole and doesn't have any concept of a woman not returning his attention, but I don't think he's actively such a garbage person that he'd try to press Jill for sexual favors of any kind. I think it's more likely he'd try to leverage his threat of legal action against MC to force Jill to try and drive MC away from her, which may just give those uninterested in her an actual out (though that hasn't seemed to stick previously, so who knows). But I find that more likely, as that would give Tybalt more time to try and charm Jill himself (at least in his mind that'd be the theory). That would also be more fitting to his character, from what we've seen.
Yeah, he has the watermelon thing, but I think that makes Tybalt more sad than anything. I don't pity him, but he doesn't seem to know how to interact with a woman at all. He's interested in Jill and thinks his interest in her alone is enough to warrant her being attracted to him too. That she isn't seems to just mystify him, though I think he's started to put this together. I don't think Tybalt is stupid, just up his own ass.
