I think the confliction with the rest of their lives was something that made itself much more apparent in the movie than in the book, like the scene when Ennis and Jack get caught kissing outside of Ennis' residence when they meet up for the first time in forever. That was such a strong moment, I mean from an emotional standpoint, that moment crushed Ennis' wife, but I as well as a few others in the theater couldn't do anything buy laugh. It wasn't really funny just, incomprehensible. Jake's character was simply torn, the scene where he was leaving Ennis' after finding out that he couldn't be with him because he had the girls that day, that was a very emotionally strong scene, showing the conflict he held in his heart for what was going on in his life.
