I'd Rather Twitch Than Fight - S3-E10
Question: Darren was angry at Samantha for getting rid of his favorite coat so, why was he even angrier when he got it back?
Answer: I haven't seen the episode, but generally in the show, Darrin was always suspicious that Samantha always used some kind of witchcraft for any situation (even if she didn't). He probably figured the same thing with the coat while in her possession.
You should watch the episodes in question before giving an answer so you know what you're talking about.
Question: Is there some reason why Samantha wears the same exact "Heart Pendant Necklace" in every single episode? It seems odd that she only has one necklace all the time.
Answer: The original diamond and white gold heart necklace was given to Elizabeth Montgomery by her then real-life husband, William Asher, who also directed the show. She wore it in nearly every early episode. When the necklace was lost or stolen about mid-way through the series, Montgomery had two replicas made from rhinestones. She wore either one of those for the rest of the show's run.
Question: In one episode (not sure which one but it was in the Dick York era), Darrin was arguing with Samantha and said something like "Confiding in a woman is like broadcasting by Telstar." What exactly does that mean and what was Telstar?
Answer: The Telstar Reference was in Dangerous Diaper Dan when Samantha engages in too much gossip.
Samantha the Dressmaker - S2-E22
Question: Who was watching Tabitha when they went to Paris?
Answer: This may be a plot inconsistency but probably a scene was shortened or edited out completely from the original episode that explained this. This is typical for syndicated reruns so that cable stations can air more commercials. The result is plot inconsistencies. Most likely Aunt Clara or another relative was summoned to watch Tabitha.
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.
