Visible crew/equipment: In the final scene in the Magic Box where Buffy cries, in several shots of Buffy you can see, in the right of the shot, the sleeve of a white shirt, which none of the characters are wearing.
Revealing mistake: When Faith is being chased by Buffy she jumps over a brick wall but as she does the wall wobbles.
Continuity mistake: After Buffy slams the Gavrok spider thing on the ground with her back, she gets pulled up by Angel. We see this shot from the back, and we see that the Gavrok is no longer on the floor or on her jacket. In the very next shot, we see Angel kick it across the floor. Where did it come from?
Revealing mistake: In the scene where Giles and Ethan Rayne are drinking in the bar, the shots cut between Giles and Ethan frequently. When on Giles, you can see Ethan's hands/arms and his glass in the foreground of the shot, but almost every time the shot switches back to Ethan he's in a different position with no time to have moved. (00:14:40)
Once More, With Feeling - S6-E7
Continuity mistake: The demons that Buffy fights in 'Once More, With Feeling' change positions on the floor during the next song. (00:43:45)
Continuity mistake: When the portal is opened Buffy crawls around to the other side of her bed yet just as the portal closes there is a wide shot and she isn't next to the bed.
Continuity mistake: When Buffy is hitting the punching bag near the end of the episode and Riley comes in she has bandages wrapped around both her hands but in the close up shot there is only a bandage on her left hand.
Revealing mistake: In the scene where Drusilla and the new reformed Angelus are in the shopping mall and they got blown over the side after Buffy fires the grenade launcher at the Judge, you can tell that it was Mike Mass and not David Boreanaz that got blown over the side.
Revealing mistake: In the opening of the season 6 episode "Two To Go", Willow has gone crazy and is trying to kill the two remaining members of the Trio, so she is pulling the brick wall of the jail apart brick by brick. The problem is that if you look carefully, they are obviously not bricks being pulled away; they look more like plastic or plaster.
Once More, With Feeling - S6-E7
Continuity mistake: In the musical episode, 'Once More, With Feeling', when Buffy is singing her song in the Bronze, 'Something to Sing About', she breaks a pool cue over a demon's head. She holds the remains in her right hand and clubs another demon in the face with it, then the camera cuts to another angle and it's in her left hand when she stabs the next demon with it.
End Of Days - S7-E21
Continuity mistake: At the beginning of the episode when the Potentials are fighting the ubervamps, when they see the second one they move away from it. You can see in the bottom right hand corner of the screen that the ubervamp already has a Potential. In the next shot you see it jump down and grab a Potential.
The Freshman - S4-E1
Visible crew/equipment: When Buffy and Xander are doing some research, check the left side of the screen in a wide shot, when Xander asks "how far back do the disappearances go?" You may need to turn the brightness up, but there's a boom mike bobbing around. (00:34:25)
Other mistake: Towards the end of the episode when Spike tells Buffy to stake him and removes his shirt, you can see that he has a tan on his upper back/neck to his hairline from wearing a t-shirt.
Character mistake: In this episode, Buffy says that Drusilla could be alive because they 'never saw her body'. Drusilla is a vampire; if she was dead, there wouldn't be a body to see - as the slayer, Buffy knows this.
Visible crew/equipment: When Xander is leaning over the hole in the cemetery into which Buffy and Dawn have fallen, he causes the edge of the hole to collapse. Seen from below, everything is fine, but the shot from above Xander shows a hand grabbing hold of the back of his trousers and his briefs are visible.
Continuity mistake: New boss Lorraine unfolds her arms twice. (00:39:05)
Nightmares - S1-E10
Continuity mistake: In the scene where we see Buffy's mum drop her off at school, when Buffy is worrying that her dad will not show up, we firstly see Joyce's seatbelt is on. We then see her again and it is still on. However after the shot goes back from Buffy to herself, we can see her seatbelt is off. Then when the shot comes back to her again it is back on.
Lover's Walk - S3-E8
Other mistake: In the final scene, where Spike drives down the road while singing 'My Way' he turns the steering wheel significantly, but in the external shots the car is travelling down a straight road, with no bends. He is turning it sharply to the right as the camera cuts to outside, but the car continues straight ahead.
Answer: She has superpowers, ergo fast movement. The reason she outruns him so easily in "Touched" is that she stops trying to actually fight him and just dodges instead.
