S1·E20 Agent of the Eagle

Don Alejandro tells Diego he's received a letter from a friend in the capital telling him that the new commandante, Capitan Juan Ortega, has the reputation of being an honest and fair man. When Ortega arrives, he doesn't act that way. He treats Sergeant Garcia with contempt and is openly arrogant toward the civilians. The reason for this is revealed when Ortega meets the magistrado and informs him that the real commandante has been ambushed and murdered, on orders of the Eagle.
