Continuity: When Buffy and Sheila are walking out of school after the meeting with Snyder, Xander runs up to talk to them. He mentions during this scene how Buffy will be helping out at the Parent-Teacher Night, but he shouldn't know this - Buffy only just found out about it in the meeting with Snyder.

Audio problem: When Xander, Willow and Umpada meet up at The Bronze, the song the band is playing is at the point of a guitar solo. If you watch Oz (who has already been established as 'lead guitarist') on stage in the background; he's blatantly NOT playing that solo. The hand movements don't match up.

Continuity: When Buffy opened the trunk for the first time, the corpse of the real Ampata is lying with its head to the right of the trunk. When she opens it the second time, the corpse is lying with its head on the other side.

Plot hole: When Ampata is first released from her imprisonment, why didn't she break the seal then? She knew the only way to re-mummify her was to put the seal back together, so why not shatter it completely instead of leaving it in large fragments?

Continuity: Ampata tells Buffy she has no lipstick, but earlier that episode we saw her using lipstick, in the high school bathroom right before the bodyguard attacked her.

Continuity: When Buffy is at the party, we see that she is wearing black shoes with a high heel. But when she is fighting Machida, the heels are considerably lower.

Continuity: Willow is turned into a ghost. Throughout the entire episode, she can't touch anything (can't turn the pages of a book, etc.), yet towards the end when she and Giles go to Ethan's shop, and she leaves, you can hear that she opened and closed the door, even though she can walk through walls and can't actually touch the door. The curtain moves when she leaves too.

Continuity: The vampire Angel fights in Buffy's house was never invited in.

Other: When Buffy and Willow find the picture of the noblewoman in the Watcher's Diaries, Buffy asks "Who is she?" and Willow replies "It doesn't say", but if you watch closely you can see that during the brief shot of the book her name is visible next to her picture.

Audio problem: Just before Willow got turned into a ghost, she started to talk, but it wasn't her voice that was talking, it sounded like Cordelia.

Plot hole: Giles tells Willow to leave him while he extracts information from Ethan on how to break the costume spell. By the time Giles smashes the statue Willow has already found the others, who had left the house where she thought they were and are hiding in a completely different area of the town. No matter how long it took Giles to beat the information out of Ethan, there is no way Willow could have gotten back to the house, realised they were gone and tracked them down before the spell was broken. It is also impossible she could have happened across them - they were hiding, after all.

Continuity: Buffy knew that Spike was the vampire Ford asked to come, but Ford never told her that, nor did anyone else.

Continuity: When Buffy is fighting the vampire in the alley, it's fairly obvious that it's her stunt double fighting because Sarah's hair is slightly shorter, and isn't as full at the ends.

Revealing: When Buffy and Giles are talking in the school in the final scene, the same extra (in a beige shirt and blue jeans) walks out of the room behind Buffy twice.

Continuity: Cordelia tells the Scoobies that Giles was talking to the police about a homicide, but this wasn't mentioned in the time that she was in the room.

Continuity: When Giles is making calls in his apartment, he takes his glasses off and drops them on the desk, just above the notebook with his list of names. But in the close up of the notebook, the glasses are now on the top of the notebook.

Continuity: At the end of the episode, Buffy complains to Willow and Xander that she will have to blow her allowance on getting the tattoo removed before her Mom sees it. Moments later when Buffy is talking to Giles, the tattoo is gone.

Continuity: If Spike and his gang only take a few hours to break through the door to Ford's club in 'Lie To Me' (which we are told is six feet of solid steel), why can't Angel break through a thin wire door that visibly shakes every time he hits it, given the same amount of time, in the episode 'What's My Line? Part 1'?

Continuity: When Buffy is fighting Kendra the fragments of the table she is thrown onto have disappeared when she stands up again.

Revealing: Although the mirror in Buffy's room is mostly covered by photos, Angel's reflection can be seen for a split second as he walks past it to pick up the photo of Buffy ice-skating.
