The Trial and Error of Aunt Clara - S3-E21
Continuity mistake: When Samantha opens the door, you can see the 3 pictures by the door. The middle picture is straight. When the camera cuts to Samantha and Aunt Clara and returns to Larry at the door, the middle picture is crooked... a necessary plot point to distract Larry from the desk in the stair case.
The Trial and Error of Aunt Clara - S3-E21
Continuity mistake: When the coven is reading the case against Clara, the gavel is lying in the middle of Judge Bean's Bench. The camera cuts to Darrin then returns to the Coven, who is still reading their case against Clara. The gavel is suddenly on the wooden platform. There is no indication the gavel had been used as the coven is still reading their case against Clara.
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.
