As for Harley and Ivy… that one has been in the cards and hinted at since Batman: The Animated Series, where Ivy helps console Harley to not need abusive men in her life. It wasn’t overt until much later in the comics, but it definitely has a lot of foundation.

And I didn’t pick up on any of it there either, but at least there Ivy wasn’t straight-up cheating on her fiance.

Finn being Force sensitive is a paper thin revelation, and Rey, the person he wanted to tell, never even learns about it on-screen. Most people only realized what that was all about from post-release interviews or tweets.

I 100% believed he was trying to tell Rey he loved her and was shocked to find people read it differently. I may not have picked up on Stormpilot, but Finn’s simp act is hard to miss. Why else would he rush over to the Death Star ruins?
