Continuity mistake: When Anya is sneaking into Spikes room after she closes the door the shot goes to spike and the sheet is lying square across his stomach and the camera goes back to Anya she then walks over to the chest of drawers and we see spike in the shot and the sheet is now lying at an angle so we can see his hip.julie sheridan
Continuity mistake: When Buffy and Willow are talking about the sham of Thanksgiving Day at the groundbreaking ceremony, on one angle (the one where Buffy's face is shown) there is a strong wind blowing, moving their hair about, but in the other (when you can see Willow's face) their hair aren't moving.
Continuity mistake: In 'Gone', when invisible Buffy is typing on the social worker's keyboard the letter 'B' is pressed several times.

Continuity mistake: In 'Graduation Day, Part 1' when Buffy and Faith are fighting Faith falls into a table, knocking all the comics on it onto the floor. In one or two later shots you can see (on the very edge of the screen) that there's still a comic on it. (00:38:20)Shay
Continuity mistake: In 'Becoming, part 1' as Buffy kneels over Kendra's corpse you can see the door over her shoulder, it stays closed all the time. There is a cut to a shot of Buffy from behind showing a cop raising his gun, but he couldn't have come through the door without us seeing him in the last shot. (00:43:10)Shay
Audio problem: Near the end of the episode when Giles, Tara, Faith/Buffy and Willow arrive at the church and a police officer tries to stop them going inside Willow says, 'Oh no you don't understand (or words to that effect) but her mouth doesn't move at all, it was clearly dubbed.
