Continuity mistake: It's understandable with Tabitha being so young, but when she is on the couch and doll is zapped next to her, the scene editing is very choppy. Tabitha scoots about 8 inches to the right (center of couch) and is turned. It's very noticeable when looking at the green couch pillow beside/behind Tabitha.
Continuity mistake: The front door in the episode is white with no window at the top. The door is normally green with a half moon, frosted, window at the top. At the end when Ho Ho comes with Pony then Larry and the client show up the porch is also flatter and different.
Continuity mistake: In the final scene, when Darrin flips up the picture of Endora, when the camera cuts back onto the frame, it's color.
Continuity mistake: The front door changes color and style from white to green then back to white at the end of the show when Larry is talking to Darrin.
Answer: Larry had been telling Darrin what it means psychologically that Samantha gave the coat away. Larry said giving it away meant she's happy being married but if she liked the coat it means she desires to be single and carefree. So when Darrin sees the coat, he immediately thinks Samantha doesn't want to be married and the fact that she twitched it means (in his mind) she wants to be a single, carefree witch again.
