Continuity mistake: When Buffy is walking forwards through Angel's dust in 'The Wish' there's a vampire running towards her, only a few steps behind. Then there's a shot of her walking forwards taken from another angle, then when we can see behind her again the same vampire hasn't moved forwards at all, he's still running from 3 steps behind her. (00:41:25)
Continuity mistake: At the beginning of the episode when Buffy is fighting the demon, she stabs it and the demon lands half on top of her. When they fall to the ground, you can see a big stain on her pants where the demon touched her. But when she stands up, her pants are clean.
Visible crew/equipment: There's a boom mic visible when Cordelia is talking to Harmony and the other Cordettes. It's the first scene in the alternate universe and they're standing inside a classroom of Sunnydale High (Cordy says something about going to the Bronze).
Continuity mistake: During season 7 we are told several times that the First cannot take corporeal form, ie. it cannot touch things. However, in its first appearance in the season 3 episode 'Amends', when it manifests as Jenny Calender and runs its fingers through Angel's hair you can see his hair moving underneath her fingers. It wouldn't be able to do this if it weren't corporeal. (00:15:50)
Factual error: In Amends, season three, one of the movies playing at the theater is 'Abilene,' which was not released until March 13, 1999 ; three months after this episode was aired (and probably five months after it was filmed, which is interesting). (00:43:10)
Gingerbread - S3-E11
Factual error: There is a short picture of a 17th century German newspaper. The actual text however not only is written in modern High German as opposed to Mid-High German, but also is full of errors (mixing female articles with male nouns is only one example). Funnily enough, Giles' incantation at the end of the episode is in correct German. (00:30:45)
Gingerbread - S3-E11
Continuity mistake: In the previous episode 'Amends', Buffy was sporting a brand new short fringe. In this episode it has grown out. Completely.
Gingerbread - S3-E11
Factual error: When Giles and Cordelia are driving to save the girls from getting burned at the stake and are making the potion to make the demon show his true face Giles tells Cordelia to shred the Wolfsbane. This is a huge mistake as any Witch will know (my sister pointed this out to me) that Wolfsbane is highly poisonous and should never be touched with bare hands and Cordelia didn't have gloves or anything.
Visible crew/equipment: Near the start, just after Buffy kicks the vampire onto the roundabout, check the top left corner of the screen as she says her line - boom in shot. (00:02:35)
Continuity mistake: In the library, a book in front of Buffy begins to slide off of a stack of books. Change of camera and book is back on top of stack.
Plot hole: When Buffy enters the house to rescue her mother she uses a stake to stop the front door from closing. A vampire then grabs it and the door closes. Why did Buffy use a stake knowing that there was a vampire there when she was almost killed by a vampire with her own stake earlier in the episode because Giles had been injecting her with a muscle relaxant?
Visible crew/equipment: While Buffy, Giles, and the gang are in the library fighting the demon that came out of the Hellmouth, the camera zooms toward the door that leads into the hall, where you can see Xander being chased by the dead guys. As the camera zooms in closer towards the round window in the door, you can see its reflection in the glass when the strobe light flashes. (00:36:10)
Continuity mistake: In the basement scene, with Jack and Xander, the bomb counts down from 13 to 10 seconds. Then after Xander says his line, the bomb again shows 13 seconds.
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.
