Corrected entry: When Buffy complains about Faith's methods, Giles reminds her "She did kill one of them in the alley", but during the alley fight Faith didn't kill anyone. Buffy staked all four vampires.
Corrected entry: How does Wesley have the exact key to fit the manacles in Angel's mansion (in the scene where he frees Faith)? We never see him picking them up or taking them from Angel.
Correction: The Council has access to many magical resources. It's quite likely they have enchanted skeleton keys to fit certain types of locks, especially given what we learn about the Council's wetworks squads.
Corrected entry: In 'Graduation Day, Part 2' all the parents run for their lives after the Mayor ascends. Doesn't a single one of them worry about the kids they're leaving behind or try to get them to run too? (00:33:20)
Correction: Wouldn't the kids have explained the situation to them? After all, you don't normally take a weapon to your graduation, and you would be smartly dressed for the occasion.
Corrected entry: If even Faith can instantly realise that the gang would be willing to trade the Box of Gavrok for Willow's life, we can assume Willow knows it too. Why, then, when she escapes from the locked room in Town Hall, does she hang around to read up on the Books of Ascension? If she had escaped they could have destroyed the box, and the Mayor's plan would have been stopped, whether he had the books or not.
Correction: Willow knows from the gang's reconnaissance that all the entrances and exits from the building are guarded, but there are few if any guards within the building itself. If she tried to escape she would certainly be caught. Knowing that her friends would try to rescue her even if they weren't willing to sacrifice the box, she did some snooping on the off-chance that it would prove useful.
Corrected entry: When Faith asks Buffy what her toughest kill was, she tells her "The Three", from the season one episode "Angel", but in that episode Buffy barely encountered them. She saw them once in an alley and was barely harmed in the encounter - in the end, it was Darla who killed them. One would assume her first thoughts would be of someone like the Master (who killed her) or The Judge (who was indestructible).
Correction: Buffy is distracted because she is thinking about her actual toughest kill: Angel. She mentally grasps for some fight that was not witnessed by anyone present (who might contradict its difficulty) and comes up with the Three. Neither fight with the Master lasted more than a few minutes and the Judge was killed in one hit from a rocket launcher.
Revelations - S3-E7
Corrected entry: In 'Revelations', after Mrs. Post attacks Giles, when Buffy finds him he manages to tell her that living flame must be used to destroy the Glove of Mynhgon before the paramedics take him away. Since Angel already knew this, wouldn't it have been much more useful if he had warned her that Mrs. Post was an imposter?
Correction: This mistake falls under the "why" rule. Giles took a nasty knock to the head and is currently in an emergent medical situation, so it's not surprising that he isn't thinking clearly. In this state, it is more important to tell Buffy how to destroy the Glove immediately and prevent it from falling into anyone's hands than to tell her to keep it away from one specific person.
Corrected entry: In 'The Wish', considering the necklace is the source of all Anya's powers she's fairly careless with it. She puts it around Cordy's neck and lets her take it into the Bizzaro World, where it could easily have been smashed during either of the vampire attacks. In fact, if it hadn't been for Giles the necklace would have been incinerated.
Correction: This is an indicator of Anyanka's hubris; a character flaw, not a movie mistake. As she tells Giles, all her powers are not in the wishing that the amulet allows, but do use that amulet as a power source - she may not even be aware that destroying the amulet will also rob her of her immortality and strength. The magic amulet probably enjoys some amount of resistance to heat, cold, and magical intrusion and is very valuable, making individuals who encounter it unlikely to destroy it intentionally. No doubt Anyanka has some homing connection to it that she planned to take advantage of after her tour of "interesting" Sunnydale.
Corrected entry: In 'Bewitched, Bothered And Bewildered' we see the interior of Xander's room, and a guitar is resting against the wall in the background. Next season, in 'The Zeppo', he asks Oz if it's hard to play the guitar. If he already has a guitar you'd assume he knew how to play it, or had at least tried to learn in the past year.
Correction: Xander's character isn't often driven or committed to non-life-threatening causes. In Season 5's "The Replacement," his friends comment that the Xander clone is much more decisive and determined than original Xander. It's quite likely that such a person would pick up a secondhand guitar on a lark but never follow through and learn how to play it - after all, he did fantasize about playing the guitar to impress Buffy way back in "Teacher's Pet."
Corrected entry: At first Anya supposedly has no knowledge of what happened during the events of 'The Wish', since she is as mystified as Cordelia to find her necklace gone. During 'Doppelgangland', however, she seems to know exactly what happened; she discusses it with D'Hoffryn and recognises Vampire Willow as soon as she sees her.
Correction: At the end of "The Wish," Anya is in a state of shock: she's suddenly lost her center of power, been transformed into a human, and jumped dimensions all in an instant. It takes her a few minutes to adjust, take stock, realize what has happened, and start panicking, all of which happens after she runs off following Cordelia and attempting to grant more wishes. No wonder she's disoriented.
Corrected entry: In the alternative universe, the residents of Sunnydale are aware of the presence of the vampires, who are killing people in horrifying numbers. So why doesn't everybody move away, as they do in Season 7 when the apocalypse looms?
Correction: One might also ask how the Master escaped the Hellmouth without ending the world, or why Giles never called for assistance from the Slayer until now. The answer is that Anyanka has some degree of artistic license when granting wishes - we see this in season 7, when she accepts a wish to turn an ex-boyfriend into a worm and actually transforms him into a burrowing beast. Anyanka thinks Bizarro Sunnydale is more interesting with humans around to kill, so she creates a world that fulfills her interpretation.
Gingerbread - S3-E11
Corrected entry: If all of Giles' and Willow's books were burnt, or just drenched in water; why is it in latter episodes, his books are all in good shape?
Correction: Some or all could be replacements.
Corrected entry: In the episode "Beauty And The Beasts" where Buffy has to see the school psychiatrist she finds him dead in his office, when she walks into his office she says she's on time for her two o'clock appointment but the clock over the door of the office reads twenty past four. (00:25:55 - 00:26:55)
Correction: This could be sarcasm by Buffy. She knows she's late, but she has to be there.
Corrected entry: Giles says in 'The Wish' that destroying Anyanka's power source will reverse all her wishes. Surely Cordelia's can't have been the only wish that caused a temporal fold or similar history changing event? And if not, then shouldn't the world now be radically different in some way?
Correction: Cordelia's isn't the first temporal fold, but the point of the episode is that superhero Buffy has had a tremendous effect on Sunnydale. Anyanka usually deals with common women, like Cordelia, not exceptional individuals like Buffy. Therefore, past temporal folds probably dealt with small things, like cheating husbands never meeting temptresses or never being born, none of which significantly affected world history (even Cordelia's only affects Sunnydale and Cleveland). So the world is different, just not in ways that matter to our characters.
Corrected entry: Third season, Episode 3ABB13-The Zeppo-Jack says that he couldn't raise his dead friends earlier because he "had to wait 8 months for the stars to align," but he died three weeks ago and his grandfather raised him the same night.
Correction: Jack says he was dead less than ten minutes - perhaps that affects the necessary conditions for the spell.
Corrected entry: The episode, 'The Wish', is where Buffy had never come to Sunnydale and the vampires had taken over Giles knew there was a vampire problem before Cordelia shows up and tells him to call Buffy in. Giles knew about Buffy before Cordelia tells him so why didn't Giles call Buffy about the problem before it got so out of hand if he already knew of her and the problem.
Corrected entry: During 'The Wish', when history has changed and the Master has risen, where are Collin, Darla and the Anointed One, the Three or any of the other favoured acolytes from season 1? Buffy never killed Collin or the Three, Angel wouldn't have killed Darla if it hadn't been for Buffy and the Master would surely have been able to protect the Anointed One from Spike. Even allowing for Angel and the White Hats to have taken out one or two of them, surely at least one of the group should have been there? This is technically the real world as altered by Anyanka's temporal fold, not any kind of alternate dimension. This is what the world would have been like if Buffy hadn't come to Sunnydale, so anybody who would be alive if it weren't for Buffy should still be alive.
Correction: Colin and the anointed one were the same person and with the prophecy regarding the anointed one being linked to the slayer, no slayer equals no anointed one, same with the three, they were only called on to take out the slayer. Which leaves Darla, who still could have either been killed by Angel, after all she was part of his destiny.
Correction: He was talking about the one Faith killed earlier outside the Bronze, when Buffy first met her.
