Trapper found himself in a dark place. If it hadn't been for Hawkeye, there's no telling what Trapper might have done. He might have even gone so far as to kill that wounded Chinese prisoner. God how he wanted to. After all, that kid was responsible for the death of Trapper's patient, all because of an altercation in the OR with a knife; a knife that the kid never should have had. Nurses were injured and their nerves rattled. Trapper knew he should apologize. He never should have gotten worked up. But life was precious, especially during times of war.
