Bonanza/The Stillness Within
Special Guest Star: Jo Van Fleet (Ellen Dobbs)
Blinded in an explosion, Joe Cartwright, uncertain as to whether his sight will ever be restored, bitterly cuts himself off from the rest of his family. Enter Ellen Dobbs from San Francisco, who specializes in teaching the blind how to cope with the "sighted" world. Electing not to tell Joe that Ellen is herself sightless, Ben wonders if he made the right decision as Joe's anger and unwillingness to learn from Ellen threatens to permanently divide the Cartwrights.
