I found some cool trivia related to this episode:
Face/Off: The Nic Cage and John Travolta body-swap thriller is referenced numerous times. Producer David Fury wanted to call the two-parter
Faith/Off.
Faith as Buffy arguing with herself in the mirror echoes Robert DeNiro in
Taxi Driver.
The Watcher's Council: They tried to kidnap Faith before (Consequences), with equally hilarious results.
Willow and Tara: This week they stroke carpet. Blimey.
Spike and Buffy. When Faith flirts with Spike, there's a lot of sexual tension going on. Wonder what will become of that?
Cans of Film: When Buffy drives out of the Council's warehouse, we can see cans of film. Spot the re-use of a studio building.
A
Stevedore is a person who loads and unloads boats on the docks. They're really rather rugged.
Amy Powell plays the newsreader we always see in Buffy.
