Fans discuss the Svengali reference from the episode, with one poster providing the dictionary definition from the 1894 novel by George du Maurier.
Svengali was a guy (don't know when he lived, however, he could be fictional for all I know :)) who had a power (so to speak) over women and could transform their personalities and/or make them do whatever he wanted. Much like the doctor did to Elaine (obviously):
Doctor: You CAN and you WILL talk to him. Elaine: ok.
Svengali all the way......
