14x2 - Bonanza

Little Joe learns of the tragic and savagely brutal circumstances of Alice's death and is determined to bring her killers to justice. While a good part of this episode focuses on the pursuit of the thugs that killed Alice, what made this episode was a moving scene where Ben comforts Joe over the death of his new wife. Sitting in the smoldering ruins of what was Joe's new home, Ben (who rarely gets emotional) and the ever-emotional Joe really grieve for Alice.
