Bettis question... (spoilers)
I watched this through twice; and one thing confused me. There's a scene where Bettis is out with the other main characters on a patrol. They start getting shelled and he runs off. We don't see him again until the group gets back into the town of Bastogne, and Bettis yells to them that there's hot food. In the next scene, he seems to be serving them the food and there's some discussion as if he'd been serving back at the rear of the lines. He also is resistant (understandably so) to go back when every ambulatory man is told to grab a rifle and go back to the front. Unfortunately he's killed in another round of shelling in the kitchen. My question is: was he allowed to go AWOL and return to the back of the lines? Did I miss something? Thanks.
Just to note, this is scheduled to air again on TCM this Saturday (Jan. 16, 2010).
