Because Erin Murphy was ill, her sister Diane played Tabitha in this episode. The girls were fraternal twins and looked a good deal alike when they were younger, so they could alternate playing Tabitha. But at this point in their lives, they no longer resembled each other as they once did - and viewers noticed. Reportedly, the producers received a lot of letters asking "Who was that girl?"
