Bonanza - Season 4 - Eps 1: The First Born
Clay Stafford signs on to work for the Cartwrights and shortly afterwards shoots and kills a man who accuses him of cheating at poker. The miners warn Clay to leave town, but it appears he killed in self-defense. Surprisingly, he tells Little Joe that he is his half-brother, and Marie was his mother. Ben listens to his story and takes his word for it, but Adam and Hoss think he should wire the judge in New Orleans to confirm Clay's real identity. Meanwhile, Clay and Joe develop a close relationship, but the vengeful miners still want Clay out of Virginia City and their first warning, is when Joe is beaten up by them. Ultimately, Clay decides life on the ranch is not for him.
