I think you can fairly easily cut out the banter between Finn and Poe. It would tighten up that scene a bit, which in itself could be a good thing.
Since there is NO ultimate satisfaction on “what Finn wanted to say” in the movie, it would be better to remove all of it.
Sigh … when you have to explain things in a tweet or a book for MAJOR plot elements or unanswered questions … you know you are doing something wrong in a movie.
