RILEY, YOU BIG LUG A small shrine to the dumbest man on TV. This week: This week his brain switches off, and he just becomes one big sex object. No noticeable change. "I've got that thing." Riley's attempts to subtly seduce Buffy away for a quickie in front of her friends are... well, hardly covert.

Sarah Michelle Gellar was away shooting an episode of Angel. Hence her being bed-ridden for much of this week, poor lamb.

This week: Xander will be mostly selling ice-cream. Badly.

Incidental music: This episode opens with a whole minute of great music to accompany the creepy tracking shot through the house. The episode gets worse, but the music stays great. We're including the bit with Giles.

Lowell House: As well as being conveniently built on top of caves, and having a secret military installation beneath it, Lowell House used to be a home for disturbed children.

Tiled bathrooms: Lowell House has a magnificently tiled bathroom that is also more than a little strange. Roughly the size of a TARDIS, it contains a bath, shower, urinal, toilet paper, but no toilet or lock. Oh, and plenty of ghosts.

Forest and Graham: Get into a lift in the middle of an earthquake, proving all Initiative boys are dim.

"People are going all Felicity with their hair.": Xander's comment refers to American show Felicity, the star of which cut off her hair between seasons, much to the annoyance of her network bosses.

Giles sings: Yes, that really is Anthony Stewart Head singing. He was in the Rocky Horror Show, you know. And he'll sing again this season.
