 The final episode to feature Kitty is also the last one where Matt gets shot in the shoulder -- he takes down a shotgun-wielding bank robber but takes a load of buckshot in his gun arm. When Matt wakes, he says: "This arm just doesn t feel right." Matt soon discovers that rehabilitating the arm will be a long, slow process and (ironically) after a quarrel with Kitty, he decides to turn in his badge and leave town to be a drifter. Good idea, because the remaining bank robbers soon come back looking for Matt s scalp. When Kitty convinces them he s left, the robbers leave too, but determine that Matt has to live off the land by fishing and "this part of Kansas ain t exactly awash with rivers and cricks." Meanwhile, Matt comes upon a young Army deserter, who ran out after his unit massacred a group of unarmed Indians (My Lai, anyone?). A bounty hunter (David Huddleston in a cameo) menaces the deserter, but Matt distracts him long enough for the deserter (Dennis Redfield) to whip out his revolver and fire a warning shot. The deserter, Lem, takes a liking to Matt and brags about his prowess with a gun, all the while gloating about how he would never fire a bullet into another man. Matt considers that a dangerous contradiction and says so in no uncertain terms. Lem s ideals are tested when the robbers come upon their hideout and start blazing away, intending to get Matt and take Lem down with him.
