There are no character or story details revealed, but there was one original Twilight Zone episode where Rod Serling mentioned the phrase “point of origin” in his opening narration. It was for an episode called “The Call”, and this is what he said:
“Norman Blane, whose greatest fear is that, if he were to vanish from the Earth tomorrow, no one will notice, or mourn, or question, and whose greatest sadness is the realization that he is probably right. Sofa, coffee table, chair, and pet; solitary decorations in a life noted chiefly for its isolation. Point of origin and point of destination for Norman Blane, whose days and nights are routinely swallowed into unhappy silence.
