So originally this was a 90-minute episode. In syndication it runs as 2 separate hour-long parts. It is said that some scenes were deleted to accomplish this, but some scenes were also added to pad out the time, such as extra flashback scenes. Bizarrely, there's also a scene near the start of part 2 where Janet is making a breakfast omelet for David. This scene was lifted from the season 4 episode Bradford vs Bradford. Very strange.
