I still don’t think there’s a romance implied on her part going towards him. I think he feels like a romantic attachment is something he can use (and enjoy should his ploy to flip her actually work), but I have never, in all my rewatches of The Last Jedi, seen it coming from her direction, towards him. I’m not denying there aren’t charged moments, scenes, and an undercurrent making itself felt. But I’m also saying that aspect was placed in the narrative for a very specific purpose, and that purpose came to its logical conclusion at the end of the movie when she rejected him outright.

Basically: He put it out there, sure. And she said “I don’t like you like that. I don’t like you at all.”

The throne room is a complicated, dramatically satisfying, amazing back and forth. But she’s not there to get a boyfriend. She’s there to win a war. He’s there to turn her so he can use her to fulfill his power fantasy. That’s the dynamic. It’s laid fully bare by the end what it really was, and said as plainly as possible in the text and the subtext by the end of the movie.

Reylo started as run-of-the-mill fun fanfiction and ended up becoming - basically - a political wedge issue within fandom circles. It grew to encompass symbolic aspects far beyond the story it sprang from, and came to represent larger fandom concerns (and legitimate injustices within those circles), and honestly was like a giant vortex of personal projection, fueled largely by substitution of symbolic meaning for actual meaning.

Within The Last Jedi itself, though? “Reylo” was basically feinted at and then shut down in its final two reels. And it was shut down BY Rey. Decisively, too.
