I thibnk it was easy to miss the two shirts being together. I did the first time I saw the movie. Then, I wondered about the blood -- how did it end up on both shirts? When I saw the movie a few more times, I noticed that Ennis wipes his bloody nose on his cuff, but Jack, while grabbing Ennis to calm him down, also brushes his nose, so that answered that question for me. Both shirts came in contact with the bloody nose. That made the whole scene where Ennis finds the shirt so much more powerful. Not only did Jack tuck Ennis's shirt under, or within, his, but the blood adds extra meaning to their togetherness. This is the part that made me cry the most in my earlier viewings. Lamusica
