The scene at the dinner table

I've always been confused by that whole scene too. The only explanation I can think of is that maybe Gordo, Bible, and Grady take offense to Norman being invited into this nice little break from the war to have a hot shave and eggs, while they're left outside like the family dog who's not allowed at the dinner table. Gordo tells the horse story and sums it up with "but you weren't there" to drive home the point that they're a family and Norman is just an interloper, so it's unfair that Wardaddy has sort of taken him under his wing while they're left outside.

The horse story itself feels like it's supposed to mean something or we're supposed to infer something specific from it, but ultimately it's just a way to show how much they've gone through as a crew and serves to further alienate Norman. Because yeah, it's weird and confusing otherwise.

As for Bible, I love Shia's performance in this entire movie. The character is an emotional dude, tears up a couple different times and it feels real.

I felt that scene was all over the place. At first I thought Don saw the human in Norman and wanted to play house and for a moment to pretend he was not in the war. But then Don encourages Norman to have sex with Emma (surprised Norman went through with it considering all of his other misgivings). I felt the others came in and took offense to this because Don was never human in front of them, and he was sharing something with Norman implying the other members of the crew lacked something Norman had (humanity).

In the end, Don was just turning Norman into another soulless creature, one that did not distinguish between killing someone in a gun battle, murdering a prisoner, or assaulting a woman. The real question for me is did Norman leave that all in Fury at the end of the movie, or did it become part of him.
