Corrected entry: In Series 7 Episode 14, it is indicated several times that Principal Wood is over 30 - Xander says he's 10 years older than Buffy, Wood refers to events 'back in his 20s', but Wood also says he was 4 when his mother died. In Season 5, the episode 'Fool For Love' we are told Nikki, his mother, died in 1980. This would make him only 26/27, not into his 30s.
Correction: Wood is actualy 30, both in fool for love and lies my parents told me the subtiles show the year 1977, not 1980.
Corrected entry: In the police car, Buffy is on the left hand side of the car and Faith is on the right, but after they make it crash, they open the right hand door and Buffy is the first to get out.
Correction: If you look closer, you can see that Buffy is just standing by the passenger door, while Faith is getting the handcuff keys off the cop that was riding passenger, it doesn't show them getting out of the car. This explains the very next shot where they are unlocking each others' handcuffs with the keys.
Corrected entry: In "Becoming Part 2" Spike cuts off Drusilla's air to render her unconscious, so that he can take her with him when he flees. But it's been established throughout the show that vampires don't need to breathe, so his choke hold should not have had any result.
Correction: There are two kinds of chokes Spike could have used: the air choke and the blood choke. The air choke is obviously a way of suffocation and knock out, as well as murder. The other is the blood choke. This compresses the carotid arteries on the sides of Dru's neck, leading to her passing out due to lack of blood supply to the brain. As it has been occasionally mentioned that vamps don't breathe, and the two chokes are almost identical in appearance, Spike certainly seems to have used the blood choke.
Corrected entry: In the scene where the Mayor and Mr. Trick are reviewing security footage of Buffy and Faith entering Allan's office, Mr. Trick can be seen in the footage. As Mr. Trick is a vampire, this should not be possible, as a vampire's image can't be captured.
Correction: Vampires have no reflection, however, they can show up on film. ("They can be photographed, just not very well" according to Wesley Windham-Price.)
Corrected entry: In 'Get It Done' the First repeats Buffy's words to the Potentials to discourage them, but the words it speaks are different to Buffy's - they change from 'there's nothing I can do to stop that' to 'and nothing I can do will stop that'. Granted, the meaning is the same, but shouldn't the omnipresent evil know what it's repeating?
Correction: The First is reminding the potentials - the words don't need to be exactly the same, and the First knows that. In fact the slight change of wording is going to look less suspicious anyway.
Corrected entry: When Buffy woke up after Dracula had bitten her, the scar was on the wrong side of her neck.
Correction: We are shown Buffy looking at the scar in her bathroom mirror, causing it to flip to the other side. It is in fact on the correct side throughout the rest of the episode.
Corrected entry: In the scene where the Bogeyman comes down the hospital corridor and Buffy (who has been turned into a vampire as part of her nightmare) attacks him, she steps into direct sunlight, then runs and jumps the bogeyman in a sunny corridor, without any apparent ill effects.
Correction: She's been made into a vampire by the boy's nightmares warping reality. Vampires in his nightmares might be able to walk in sunlight just fine.
Corrected entry: The vampire Angel fights in Buffy's house was never invited in.
Correction: The vampire who came rushing in for Angel to fight was one of the spell-affected humans. Only appearances and behaviors changed the humans. None of the supernatural "rules" apply so that person with more or less a glamour prohibiting their own control wouldn't need an invite.
Corrected entry: When Sweet's henchman shows up at the Magic Box to tell Buffy that Dawn is being held hostage you can see the actor's real mouth moving inside the mouth of his costume.
Correction: That's because the henchman is wearing a mask and is moving his mouth underneath the mask.
Corrected entry: During Buffy's training montage, she is seen punching a bag with her wrists bent. First, that's going to be a weak punch, super strength or no, because she can't transfer the force from her arm and body; it just bends at the joint. Second, that's a great way to injure your wrist, because all that escaping force snaps the bend farther. You could strain or even break the joint. After six years, Buffy should know better.
Correction: That may well be true, but Buffy has superhuman strength. So, it wouldn't hurt her hands and would still pack a big enough punch.
Corrected entry: When Robin Wood goes to the basement and sees Jonathan lying on the seal, the seal is clean except for some dirt. Only a day has passed since Jonathan bled out all over it and his blood or residue of it is nowhere to be seen.
Correction: In the next episode, when The First has Spike hanging over the seal, you see the blood dripping from Spike be absorbed by the seal seconds after it hits the surface.
Corrected entry: During the final showdown Spike incapacitates Drusilla by choking her into unconsciousness. However, throughout Buffyverse material, especially on several occasions in Angel, it is pointed out specifically that this is impossible as vampires do not draw breath.
Correction: It has been explained by Joss and James Marsters that Spike did not choke Drusilla, he broke her neck.
Corrected entry: When Buffy and Spike argue about the wedding and she says "You think I don't live with the shadow of Drusilla over my head. Like you won't be thinking of her when you're making sweet love to me," you can see a crew member wearing a light sweater at the right edge of the screen.
Correction: It's Spike's head and not a crew member.
Corrected entry: When Giles hacks the lock off the cage he's in in the library, he uses an axe - the axe which belonged to the demon going after the glove in "Revelations", who Buffy killed and stole the axe from. The axe cannot be there, however, as Buffy is not in Sunnydale in this reality and therefore could not have faced this demon and taken the axe to the library.
Correction: Just because Buffy wasn't there to fight the demon, doesn't mean that somebody else couldn't have done.
Corrected entry: When we see a flashback of Spike with Drusilla, Drusilla doesn't seem to be insane, but Angel turned her insane by torturing her before making her a vampire, and she's a vampire in the flashback.
Correction: It's shown after the "What's My Line" two parter that when she's at full strength, Drusilla's ramblings are less crazed and more related to her current situations. She's always been insane, but she can (at times) make perfect sense. The reason she seemed like a deranged mental patient when she was first introduced is because she'd nearly been killed and was still fragile and displaced.
Corrected entry: in the 2nd season opener, the vampires are digging the master up and one digs w/ his hands and they begin to smoke and he says "the ground, it's consecrated, it burns." But you never see any vampires in the cemetery burning when they dig themselves out of their graves.
Correction: The Master's grave was consecrated with special rituals that Giles, Willow, and Xander performed which are more powerful than the consecration done with ordinary funeral rites. Vampires that emerge from the grave also do it quickly and explosively enough that the consecrated dirt likely never comes in contact with them.
Corrected entry: In this episode Ted suggests that the group go mini-golfing and everyone is fine with the idea and they do go. However, in the fade-out of the first episode of this season Xander suggests the same idea as a way to spend the afternoon and Willow states that there is no course in Sunny dale.
Correction: So, either a course has been built in the interim, or they go outside of the town to play.
Corrected entry: When Cordelia is murdered, her body falls off-screen with no sound of it hitting the ground. Seconds later, Vamp Willow drops the key to the book cage and we hear the noise of it clinking on the ground.
Correction: An aesthetic choice. The sound was removed entirely from the moment the camera pans over to Giles watching Cordelia being killed; you see him pulling and banging on the caged door, and there is no sound. So, it was done deliberately to achieve a specific mood for that one moment.
