Buffy the Vampire Slayer (1997) was one of the first TV series to cause quite a stir on the Internet with numerous fan sites and message boards springing up. This is acknowledged when Buffy stops in front of a noticeboard. There's a small note on the board thanking all of the Buffy fans at the official website.
Jack Conley appears as the werewolf hunter. He also appears as Sahjhan in seasons three and five in spin-off series Angel (1999).
When Cain rips on Buffy for letting the werewolf get away, saying "You know, sis, if that thing harms anyone, it's going to be on your pretty little head", it is a reflection of Buffy's responsibility for all the people killed by Angel since she had him in her power in their last fight, but felt unable to kill him. Specifically, at the very moment Cain says that line, Angel is elsewhere killing Buffy's schoolmate, Theresa.
Xander says to Oz "I know what it's like to crave the taste of freshly killed meat. To be taken over by these uncontrollable urges..." Thus, he inadvertently admits that he remembers being possessed by a hyena spirit (The Pack (1997)). Buffy calls him on it, and he admits "I said I didn't remember anything about that," but Buffy fails to pursue it.
This is the only time Oz's house is seen.
