Audio problem: When Jenny and Giles are talking and Jenny is talking about the festival, they walk behind a drinks machine and then her lips don't match up with what she says.

Revealing: When all the vampires are saying "for the dark", and one gets staked, there's a mark on his shirt where the stake's about to come through before it actually happens. Plus Buffy's hands are in the wrong place for her to have pushed that stake through anyway. Not only that, but the mark isn't even close to the vampire's heart to begin with.

Revealing: In the episode When She Was Bad, Willow, Cordy Miss. Calendar and Giles are wheeled over the bones of the Master. When Giles goes past his hand brushes against the bones and the skeleton bends revealing that it is in fact rubber

Revealing: In the scene where Absalom is speaking of the Anointed one, the line can be seen where the vampire makeup meets up with his real face. This may be seen in various scenes he is in.

Continuity: At the end of the episode when Buffy is talking to Giles about how she can't face her friends, her hair is over her ears for the entire conversation, but when she is about to walk away, her hair is suddenly tucked behind her ear and she couldn't have tucked it behind as that side of her head is still in view when the camera's on Giles.

Continuity: In the season two episode, 'When she was bad', in the scene where Buffy smashes the masters skeleton with a sledge-hammer she smashes the rib cage to pieces. Suddenly the rib cage has again become completely intact and she smashes it to hell again.

Other: In all episodes where the high school football team is mentioned, they are called the RAZORBACKS but in this episode the cheerleaders cheer for the GREENBACKS (it wouldn't even make sense if this was a nickname as SHS colours are yellow and burgandy).

Continuity: In the episode 'Some Assembly Required' Eric takes photos of Cordelia and Buffy near the start, when he's developing them later the poses in the photos are different to the way the girls were standing at the time.

Continuity: While studying at the Bronze, Buffy and Willow leave their books on the table to go and dance. Spike calls them outside to fight a vampire, and when Xander runs back inside to grab a stake the books have all been put back into Buffy's bag.

Continuity: When the Anointed One is killed by Spike, he disintegrates into dust. But in the overhead shot, there is no dust on the floor, even though it should have fallen through the bottom bars of the cage.

Continuity: In this episode, when Giles is looking for information about Spike, he finds that Spike is barely 200. But, in season four episode seven we find out that Spike is actually 126. Which would make him 124 in "School Hard."

Other: As Spike is walking down the hall, you can see a reflection of his head on a locker to his left.

Continuity: When Buffy's fighting Spike at the end of the episode, there are times when it's obvious that it's James Marsters' stunt double. Spike's hair is platinum blonde, slicked back, and all one length in the back, while the stunt double's hair is more brassy, spiked in the front, and layered in the back.

Continuity: In this episode, Spike pronounces "Angelus" differently ("AN-gel-us") than he does in subsequent episodes ("An-GEL-us"). Since he and Angelus ventured on reigns of terror together for twenty-odd years, he should know how the name is pronounced.

Continuity: When Cordelia comes up to Buffy talking about how "even slaves get minimum wage", in pretty much every shot her arms switch from being at her sides to crossed in front of her, held behind her or on her hips.

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.

Revealing: When Spike is talking to the Anointed One for the first time, one of the henchmen tries to rush him from behind and Spike backhands him without even looking, but Spike's hand movements, the reaction of the henchman and the sound of the punch connecting on the audio track are all out of sync.

Plot hole: Willow and Cordy disappear during a vampire attack. We later see that they spent the entire night hiding out in a closet, but wouldn't Buffy have gone looking for them once the vampires were gone? She knew they had run off somewhere (she mentions it to Giles when she gets a stake from the library). Instead she just goes home, leaving them still missing as far as anyone knows.

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.
