S08E26: Dark Enough to See the Stars

Young Billy Wilcox wanders onto the Ponderosa, sick, hungry, and alone. Ben finds him, and after he regains his strength, offers Billy a job. Jennifer Yardley, who with her father is visiting the Cartwrights, is interested in Billy. Billy is more concerned about a lawman that has come to town because he has a past that could be problematic: he killed a man in self-defense and ran.
