I, Darrin, Take This Witch, Samantha - S1-E1
Continuity mistake: Darrin's hair is messed up from the windstorm. When he sits down, his hair in neatly combed back as when he first arrived at the dinner party.
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.
