This episode is the first for the seven year series. The original pilot had more scenes with the gay housekeeper, Coco. However, his character was dropped and some scenes were re-shot that had him in it. You can tell which scenes were re-shot by watching Blanche's hairdo.
Notice Blanche's hair when she is sitting in the chair while she's telling Dorothy and Rose she has accepted Harry's proposal. Throughout most of the scene her hair is a little fuller, but when she's getting up to to her room, you can tell that part was filmed during a later time because she has gotten a haircut. During the rest ot the episode, her hair is fuller.
