Potter returns from Seoul to learn that Charles failed to fulfill his charity officer duties on payday. The duty gets traded and bartered among the 4077th medical staff and is finally reverted to Charles. In the meantime, a wounded North Korean comes in, soon followed by the GI who shot him. The two men are placed next to each other, making the American soldier uncomfortable. The North Korean, surprisingly, shows generosity to him but later dies and the GI feels remorse. He talks to Potter who suggests it should be a rule of war to know your enemy before you can do them in. Charles finally solves his charity collection problems by contributing for everyone.
