Yes the third episode was better.
Don’t like at all the “coy” looks in the “modern” relationship they are building between the professor’s wife and the blond who is actually using her to spy on her husband. Those looks are way out of sync with female friend relationships of the 1950s, unless they were lesbians, in which they would not have been part of a 1950s show. Apparently the directors asked themselves “how can we get today’s single women to watch the show” and came up with direction for the coy looks to make suggestive hints about where the ladies relationship could go - as in: “if we make some hints, even just if only visually, as in how the gals look at each other, the “modern girls” might keep tuning in to see where things go.
One of the reasons I like that period in time is that it is wholesome compared to today.
