Having crossed over into Parallel Time, Barnabas (Jonathan Frid) discovers that he is still a vampire. Almost immediately upon arrival, he bites the parallel version of Carolyn (Nancy Barrett), who, in this world, is the wife of William H. Loomis (formerly just plain Willie). The parallel Quentin (David Selby) is a widower, having been married to the late Angelique. Quentin takes the "new" version of Maggie Evans (Kathryn Leigh Scott), as his second wife. Arriving at Collinwood, Maggie receives a warning to leave immediately -- a warning from Angelique. This episode originally aired on March 30, 1970.
