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.
