Regular viewers of the show might be confused about Asten's personal life during it. In the episode "A Good Smack in the Mouth" in season 2, his wife was called Melissa, played by Barbara Babcock. However, in this episode, Asten's wife is called Louise, played by Barbara Tarbuck. Of course it is possible that Asten was married at least two times. However, there was absolute no hint in the show that Asten either got divorced or became a widower between these two episodes. To make the confusion perfectly, in two later episodes of season 7, "The Flight of the Nightingale" and "The Unquiet Grave", Louise also appears, but now portrayed by Cynthia Harris!
