Continuity mistake: As the Trio are discussing their plans near the end of the episode, Jonathan's arms are crossed in closeups and in other positions in wide shots. (00:36:35)
Life Serial - S6-E5
Revealing mistake: The entire scene where Buffy is experiencing accelerated time, shadows of trees move in the wind but never actually grow or shrink. Even over short increments of time, the sun can move shadows noticeably, and judging from the speed of the people around her, Buffy is in accelerated time for at least half an hour. (00:08:25)

Continuity mistake: Warren switches from holding Jonathan's magic bone with one hand to two hands between front and reverse shots. (00:19:10)

Continuity mistake: While working at the Magic Box, Buffy's horseshoe necklace constantly shifts between left, middle, and right positions, even within the time loops. (00:20:20)
Life Serial - S6-E5
Revealing mistake: In Jonathan, Warren and Andrew's van, whenever they're watching something on the monitors fed from their security cameras, you can see that the footage is actually pre-recorded due to the fact that the footage is being played through QuickTime media player.
Life Serial - S6-E5

Life Serial - S6-E5
Plot hole: In the 3rd time loop at the magic shop, the woman looking for the mummy hand looks surprised when Buffy knows what she wants. In the 2nd time loop, the woman tells Buffy that she called the shop 20 minutes earlier and was told that they had one. Therefore at least one of the shop's staff would be aware that a woman would be arriving looking for a mummy hand.
All The Way - S6-E6
Continuity mistake: When a vampire kicks through a car window trying to hit Buffy, some shards are still standing in the window frame. The angle changes, and the shards are gone. (00:37:00)
All The Way - S6-E6
Revealing mistake: In one fight scene, Buffy uses a car door to block a kick from a vampire. The window of the car breaks before the kick connects with it. In fact, it breaks while the foot is still in mid-air. (00:37:00)
All The Way - S6-E6
Visible crew/equipment: A boom mic is reflected in the window of Buffy's house when she and Xander sit outside discussing his engagement to Anya.

Once More, With Feeling - S6-E7
Continuity mistake: From the start of the second scene in the Magic Box, the doughnut and cruller on Xander's plate constantly switch places. (00:03:35 - 00:05:50)
Once More, With Feeling - S6-E7
Audio problem: In the episode 'Once More, With Feeling', when Anya sings her first few lines of the song 'I'll Never Tell', you can still hear Xander talking about omelettes in the background, but for the last few lines he speaks (from 'I could do an omelette' onwards) you can see over her shoulder that his voice is dubbed. (00:13:10)
Once More, With Feeling - S6-E7
Visible crew/equipment: Right after the "I'll never tell" song, Giles, Anya and Xander walk down the sidewalk, the cameraman is visible for a short time in the windows on their left. (00:17:05)
Once More, With Feeling - S6-E7
Revealing mistake: The knives Giles throws during Buffy's training are a very poor CGI job if you watch it in slow mo. All three knives Giles takes off the wall are identical, with a broad curved blade and a plain black handle. The first one has a transparent blade as it flies toward Buffy, then we hear it bounce off the far wall and it's way out of scale for the distance. The second knife has a diamond-patterned grip instead of a plain one. The third knife conveniently spins in midair for a second so Buffy can kick it out of the way. (00:30:35)
Once More, With Feeling - S6-E7
Continuity mistake: In the episode 'Once More, With Feeling', when Tara checks out Lethe's Bramble in the book at the Magic Box, she holds the sprig facing to the left in the close-ups, and facing to the right in the long shots. (00:32:30)
Once More, With Feeling - S6-E7
Continuity mistake: During "Something to Sing About, when Buffy sings, "You don't get to rehearse," Tara walks past the support pole behind her. In the next shot from an angle, she's closer to the middle of the room and the pole is not visible. (00:41:40)
Chosen answer: Angel is saying that he is still jealous and Buffy recognizes that this is his way of saying he wishes that they could be together. That is why they both smile.
