Yeah, you’re right - Finn’s arc really doesn’t change much by removing the scene. I suppose that including it just makes it all a lot more obvious.
I REALLY wish I could see TLJ:L with fresh eyes. I can’t help but feel like Canto Bight is rushed and that including more of the scene would help that, but perhaps it’s perfectly fine the way it is! It’s definitely the version I’ll be watching come Fall when I start my annual rewatch.
