I've loved LITB since I was a child 60+ years ago, but this episode just doesn't fly due to an implausible storyline. It's so glaring, one must either be only paying half-attention or deliberately set it aside in one's mind to be able to enjoy it. Here's what I mean: At the start, we learn that this girl, Kitty, was in Wally's class in school before her family moved away. Right there we know that Wally knows what she looks like. On top of that, we learn their parents were "best friends"; that suggests that the Cleaver boys were well-aware of the kids in the Bannerman household--that means Kitty AND any brothers or sisters she may have had. Like a previous episode where the Cleavers and the Rutherfords go on a picnic together, if these were Ward & June's best friends, all the kids were undoubtedly thrown together on multiple occasions. This also means the kids from both families were quite aware as to the approximate economic status of the other family. Wally's claims to wealth and knowing celebrities is ludicrous--Kitty would know they were blatant lies. On the other end, the idea of Kitty sending Wally a photo of herself, but which actually is her older sister, is preposterous! As already stated, Kitty had been in Wally's class so, even aside their parents' close friendship--which would bring the children together at times, he would know the photo was not of her; and, because of their parents being friends, would recognize it as being that of her older sister. The writing of this episode is so flawed, one has to wonder how it made it to final production. Why did no one speak up? When the scripts finally got to the actors, how could THEY not notice the implausibility of the storyline? I think they had to! Nothing wrong with the acting, and I must say it was fun to see the daughter of child star, Jane Withers, as Kitty Bannerman. She sure looks like her mom! 😊
