Witches and Warlocks are My Favorite Things - S3-E3
Other mistake: The exterior scene when Clara parachutes in is not the real outside we see throughout the show with neighbors including the Kravitz across the street and fewer trees...and no pine forest. Also, it's obvious Marion Lorne, who was about 80 at the time, was sitting on a swing like apparatus being lowered... understandably.

Visible crew/equipment: In the opening scene, when Samantha goes into hallway, you can see a visible equipment shadow on the wall to the right behind Samantha. When it cuts away then returns, the shadow is gone.

Revealing mistake: When Samantha, Darrin, and Aunt Clara are "frozen" in the living room by Hagatha, Enchantra, and Endora, just as Maurice is summoned and appears, Samantha moves her right foot noticeably while Darrin and Clara remain frozen.

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.
