Continuity mistake: After Phoebe jump kicks a warlock and falls to the ground, there is a blonde woman standing next to them. In the next shot of the warlock, when Piper blows him up, the woman is gone. But all of the mortals had been frozen, so she couldn't have moved. (00:37:40)
Something Wicca This Way Comes - S1-E1
Continuity mistake: In the scene when Piper and Jeremy are in the taxi, Piper gives him a fortune cookie. You can see her closing the box. In the next shot of Jeremy, you can see the box is still open. (00:31:15)
Necromancing the Stone - S5-E21
Plot hole: Piper mentions that Grams banished the Necromancer "sixty years ago" at Patty's Wiccanning. Grams soon thereafter says that the Necromancer has had "almost seventy years" to regain his strength. However, Patty was born in 1950, and this episode aired on 5/4/03, at which time Patty's Wiccanning could not have been more than 53 years earlier.
Plot hole: According to Paige's "fairy tale" the witch ends up with the prince. If this is really a past life, the sorceress ended up with the prince in the Middle Ages. So why do they have to fix it? Everything was just going the way it did according to her fairy tale, and good magic was obviously still present in the world.
Plot hole: When Phoebe and Cole are using the apple peel to find out her true love how does she not recognize that it is Cole? Even with the mask it's very clear that it is him.
Suggested correction: I was thinking the same, but it's possible she thought he was an ancestor/past life of Cole. When she visited her own past life, she recognized everyone there because of their "souls" so maybe she thought the same with him. Although you'd think they'd acknowledge that a little.
A Paige from the Past - S4-E10
Factual error: On the wall of Paige's bedroom when she was a teenager is a Metallica poster for "Garage Inc.", a CD not released until 1998 although Piper later says that Paige has gone back to 1994. (00:16:05)
Something Wicca This Way Comes - S1-E1
Continuity mistake: At the end of the episode the newspaper Prue is holding keeps changing from facing the camera to facing her. And as she turns to the house she drops her hand (and the newspaper) to her side but in the next shot she is holding it to her chest again. (00:40:25)
We're Off to See the Wizard - S4-E19
Continuity mistake: In the scene where we first see Phoebe and Cole when she's about to leave the apartment, you see she is wearing gold and white high heels but as soon as she reaches the elevator she's wearing black boots.
Plot hole: Leo suggests to Piper that they use their magic to scare Wyke into a confession. In Ex Libris (Season 2) it is established that they can't/shouldn't use their powers to punish the guilty - even if it means saving/helping an innocent. There's no way Leo would suggest such an immoral course of action.
Continuity mistake: After the potion is spilt, the green stain it leaves on Phoebe's skirt keeps changing both size and colour. (00:31:30 - 00:34:35)
Other mistake: At the beginning of the episode, when the mermaid goes underwater, she holds her breath.
The Legend of Sleepy Halliwell - S6-E14
Other mistake: In previous episodes it is stated that good witches don't freeze. But after Piper has been decapitated and her head is placed in the manor, one of the students freezes all the kids by tapping into Piper's freezing power. The kids are all good witches so they should not have frozen.
Continuity mistake: Near the beginning when Chris and Phoebe are talking in her office, the loose ends of her scarf switch from being in front of her to being over the back of her shoulders in almost every shot. (00:00:50)
Character mistake: In the attic, Melinda Warren is awed at how thick the Book of Shadows has gotten. But according to information from previous episodes, the Book was started after Melinda had died, so she wouldn't know how thick or not it was.
Thank You for Not Morphing - S1-E3
Continuity mistake: In this episode one of the shape shifting demons from across the street attempted to take the book of shadows out of the house. He managed to carry the book to the door, but could not take it past the threshold of the house. But in the later series it is always stated that evil cannot touch the book of shadows.
Continuity mistake: Piper does not light the candles before she summons Grams, but in the episode 'PreWitched' (when Grams summons Patty) we see that the candles must be kept alight to maintain the connection with the dead. (00:18:00 - 00:33:30)
Audio problem: When Prue is at the dentist, she grabs a guy and he says, "What, what did I do?" to his girlfriend, but his lips do not move.
Continuity mistake: Paige looks in the Book of Shadows and suggests that the demon they are looking for could be Belthazor, not knowing that Belthazor is Cole's demonic form. But we saw Phoebe making extensive changes to Belthazor's entry in the Book of Shadows in a previous episode, and the changes are not in evidence here. (00:01:40)
Continuity mistake: The timeline in the episode is inconsistent. Right after the first courtroom scene, we see the three sisters at home, and Phoebe says that "Cole was an angel in that courtroom yesterday." Later, Cole says that he regrets the criminal being let go, "today." But they are talking about the same events.
