OK. (I assume that you, unlike me, are not cheating). So last question, Spearchucker disappeared after the first five episodes. Why? I assure you, I'm not cheating.
They dropped Spearchucker because they realized that in a 30 minute show, they could only focus on developing so many doctors characters, so they focused on Hawkeye and Trapper. Also, there were either few (or zero) African American surgeons in the Korean War, so they wanted to be as realistic as possible.
