Last month someone posted asking about the series finale ending. Apparently they were told by someone that the final show had clips from past shows, shown at the end.
I watched that show just now, and the ending was a clip of Dorothy and Lucas at the alter getting married. The credits ran over that.
As I remembered before, there were no clips from past shows.
I would also like to add that Dorothy's wedding dress was hideously ugly. I don't know what the costume department were thinking when they dressed her up in that thing. I mean what was with all of those giant loops!!!
