Angel is referred to as a ‘puppy’ on a couple of occasions. In The Wish, vampire Willow keeps Angel locked in a cage as her plaything, and refers to him as “Puppy”. In The Harsh Light of Day, when Parker asks Buffy about the scars on her neck, she replies …

In Bad Eggs, the offspring of the Mother Bezoar is very similar to the facehugger parasite (designed by swiss artist H R Giger) in the Alien(s) movie series. The Bezoar dissection scene is also a clear nod to a scene in Aliens, in which the android Bishop (Lance Hendriksen) examines …

There’s a nice little scene in Passion where the gang’s research mode is interrupted by the unexpected appearance of two students (including Jonathan) looking for books.

In What’s My Line, Part One, Buffy excuses herself from research, so that she can go ice-skating with Angel:

Xander: “That’s untrue, Buffy. You …

In Showtime, we see a scene of Buffy, Willow and Xander in the kitchen twice - first without the sound, and the second time in a flashback (at 35.55 minutes), in which we hear them speaking telepathically. The first time the scene is shown, Buffy tucks her hair behind her …
