I feel like the Leia/Chewie thing got way overblown way fast. I noticed it on first view but it didn't even occur to me to question it.
Like, it's possible Chewie didn't wanna hug her and she sensed that too. I mean, obviously, that's me caulking over a filmmaking mistake (they were supposed to have cropped that shot & missed it in the edit) but you know, Chewie could see it as something like: the only reason Han goes out there is because Leia asked him to do it for her, and so he goes out there to talk to the lost cause, and the lost cause kills him for it.
Chewie did also flat-out try to murder her kid less than an hour ago.
So maybe a hug right at that moment wouldn't be at the top of Chewie's priorities. I dunno.
It's a very tiny moment that goes by pretty quickly, and if you're focused more on Rey than anything, it glances off.
