In Band of Brothers, Episode 5 "Crossroads", shortly before the Battalion is called to the Ardennes, there is a scene where the soldiers are sitting a tent watching a movie.
Cpt. Winters enters and finds Buck, who apparently returned to his unit after recovering from his injury. He tries to talk to him without getting any response at first. Buck seems completely apathetic and unable to participate in a proper conversation. He keeps sitting there after the others left when they were called to report to their leaders.
Maybe I missed something before, but neither did I understand what is the reason for his behaviour nor what the scene is supposed to tell me.
Can someone maybe shed some light on what is wrong with Buck in the scene and what meaning it may have to the story?
