What happened to Nan? I know Nan and Alf had a falling out but it appeared at the end of the episode that they had made up. Then she is never seen again. Is it that the episodes are shortened for American television and they left something out?
OP, yes, Alf and Nan did make up, but during one scene Laura saw her kissing a farmer's son. Another time she was shown speaking with yet another man. By her own admission she confessed to Laura that she was drawn to "bad boys". No doubt that Alf would not abide this, thus, her quick removal from the show. She and Alf experienced a good, frolicking, short-lived lark. Beautiful girl.
