Oedipus Hex - S3-E11
Continuity mistake: The contents of Sam's grocery bag change. Notice large brown shopping bag on to with edge of green vegetables sticking out. When Darrin takes the bag to the kitchen, the brown bag on top is much smaller and further inside larger bag and the tops of the vegetables are bigger and protruding more. There seems to be more vegetables in kitchen shot.
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.
