Revealing: During the fight scene at the end when Buffy is fighting the demons you see her throw one of the demons off the platform. If you watch him fall you can see him land safely on a conveniently placed mat.

Continuity: In episode 'Anne', when fighting the hell dimension demons Buffy's shoes change from trainers to plain pumps in different shots.

Other: In the episode 'Anne' Kenn tells Buffy that time in his hell dimension passes more quickly, that one day on Earth is the same as 100 years in his dimension. This means time goes roughly 36,000 times quicker. When Lily falls into the portal, it's at least 10 seconds until Buffy jumps in after her, but Lily is still just sitting there looking stunned. If times moves that much faster, 10 seconds would become over 4 days. Would Lily still have been just sitting there?

Revealing: When Buffy runs in front of the car you can see knee pads on her knees. You have to look quite closely because they are the same colour as her tights.

Continuity: When Buffy fights the guards and says, "Anyone who isn't having any fun here follow me," the top under her jacket is purple. In the next shot, when she turns to walk out, it is green, then back to purple when we see her again.

Visible crew/equipment: During one of the fight scenes in the demon dimension, there is a stunt mat visible on the left side of the screen, and a whole group of crew members visible in the background.

Continuity: In the scene where Buffy has just finished fighting the demons, she begins climbing up chains and if you look at her shoes, they continue to change until she reaches the ground above the chains and runs off.

Continuity: Lily's boyfriend is taken into an alternate dimension, where time moves quicker than ours, and is kept there until he is an old man. But when Buffy finds him, she realizes who he is because of his tattoo - which has not faded or aged in any way.

Continuity: In the episode 'Anne' when the latest people to be brought into hell are lined up with a demon talking to them, there are 3 or 4 people standing between Buffy and Lily. When the demon asks them all in turn 'Who are you?' we see him asking Lily and after that the shot rests on Buffy, but in the background we only hear him ask one more person before he gets to Buffy.

Continuity: When Joyce throws the bag with the stray cat into it into the hole, the bag lands with the knot at the top right, and shows no signs of moving. They chat for a few seconds about something to say, then when Buffy starts filling in the hole (with no sound of a moving bag), the bag's now lying with the knot on the left.

Continuity: After Buffy is supposed to meet Willow and she is walking home you can see she is wearing light blue wedge heels but when she is down in the basement she is wearing completely different purple heels.

Plot hole: When Giles calls Buffy's house, Joyce is in the kitchen, where in other episodes we see there is a telephone. Yet she doesn't answer it.

Revealing: During Faith's fight outside the Bronze in 'Faith, Hope and Trick' when she stakes the vampire, if you watch carefully, you can see the rubber stake bending.

Other: When Angel fights with Buffy in the forest you can see that he hasn't got shoes on, just socks. Later, when Buffy goes back to the mansion and Angel is chained up, he's wearing shoes. How did he manage to put them on, if he was in chains?

Revealing: In the teaser of "Beauty And The Beasts", when Jeff is running through the woods, you can see in the top left corner of several shots a lamp being used to light the scene.

Continuity: When Buffy is in the counsellor's office she is wearing a yellow kind of gauzey cardigan which alternates between being completely buttoned up to unbuttoned between shots.

Continuity: In numerous episodes, including 'Homecoming', we see vampires being killed when they weren't stabbed through the heart (the Texan girl vampire in this episode is stabbed practically in the stomach). But the show also makes an issue of the fact you have to stab a vampire directly in the heart to kill it (think the flashback in 'the Becoming, Part 2' where Buffy misses the vampire's heart, or 'Pangs' where Spike gets staked several times).

Other: When the female watcher is being destroyed after Buffy cuts off her arm. Her sleeve is empty, which is not possible, as Buffy could not have removed the arm but not the sleeve. Also the arm on the floor is removed at the elbow, but the watcher has lost the entire arm in a previous shot.

Revealing: When Gwendolyn Post fights Angel in the mansion, she breaks a long-handled shovel over her knee to create a stake. If you watch in slow motion, the handle of the shovel is pre-broken (she simply holds the two pieces together tightly), and the pieces separate just before they actually make contact with her knee.

Visible crew/equipment: In the Buffy/Faith fight right around when Buffy says "We can work this out..." You can see what appears to be a boom mike bob in and out of the frame in top left.
