Great review as always!

On the sexism front, the Brig is always portrayed as being a bit old-fashioned in his attitudes towards women. Later, this will create all kinds of friction with Sarah Jane Smith, who is quite the feminist.

Also, there is a great bit in a later serial for Jamie where a female character says that she's coming to do something, and the exchange goes something like this:

Lady Jennifer: "Wait for me!"
Jamie: "Ah, uh, Lady Jennifer, I don't think you should come."
Lady Jennifer: *crossing her arms* "Because I'm a woman?"
Jamie: "Y- uh, no! Uh, well, uh, in a way... yes."
