Guard (The Face of Evil, part 1)

A Sevateem guard once met the Fourth Doctor in the jungle outside the Sevateem settlement. When the Doctor threatened another guard with a "deadly jelly baby", this guard called the Doctor's bluff. He told the Doctor to go ahead and kill his fellow guard. Surprised, the Doctor claimed that he didn't take orders from anyone and instead demanded to be "taken to [the guard's] leader".
