Quincy and the police go to Vickie's house toward the end of this episode, only to find her not at home. Immediately, Dr. Quincy says that he is going to call Dr. Rainer, who would know where Vickie went.
How does Quincy know whether Vickie left willingly, or by herself? After all she has agoraphobia, and vowed never to leave her home again. Also, the place had to have been in a disarray after Vickie's struggle with Bohannen.
Also, with which phone did Quincy call Dr. Rainer? Bohannen had cut the phone lines to Vickie's house.
Near the end of the show, when the original owner of the gun is describing what happened to the BATF, he recalls that "eight to nine years ago" he had purchased the gun, and that "a couple months" later, it was stolen. A few seconds later, while telling his wife what happened, he said, "can you believe it, after five years they finally found it."
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!
