This plot is a takeoff on the real story of Bat Masterson being wounded by a Cpl. King (an alias) in Texas in 1876 over a girl who was killed in the fight.
During this season Bat Masterson is referred to as a 'kid'. What's interesting to note is that the real Bat Masterson was only five years difference in age than the real Wyatt Earp. In true life, Mason Dinehart (Masterson) was closer in age (20 y.o.) to the real Masterson then Hugh O'Brian (31 y.o.) was to the real Earp as the time this episode was first shown.
