Corrected entry: When Piper freezes an object it always continues with its path when it unfreezes, but when she unfreezes the knife Rick has thrown at her it drops to the floor. (00:36:20)
Pre-Witched - S3-E17
Corrected entry: Kit the cat shows up in Something Wicca This Way Comes (Episode 1,1), as the girls' familiar once they have received their powers. It is obvious that the cat just showed up by comments made by the girls, along the lines of "where did this cat come from" (not literally). However, in Pre-Witched (Episode 3,17), they make the same kinds of comments about Kit just showing up in this episode, which is supposed to have happened 6 months before Episode 1,1.
Correction: It's 6 months apart. A cat showing up once and then again 6 months later isn't cause for mistake. Simply explained through forgetting.
A Paige from the Past - S4-E10
Corrected entry: After Piper freezes the first crime scene that Cole and Phoebe (aka Frankie and Lulu) have hit, Piper unfreezes Darryl by touching him but at the beginning of the the episode when Piper and Cole are touching the car that Piper froze, to stop it from exploding after a car crash, while trying to help the woman inside, the car never unfreezes. This is somewhat inconsistent through the entire show a lot of times they can unfreeze things by touching them and then a lot of times they can only unfreeze things by Piper using her pointer finger to either unfreeze a head or a foot or some other body part. (00:30:15)
Correction: This is obviously due to intent - just touching something wouldn't unfreeze it unless Piper intended that.
Sympathy for the Demon - S5-E7
Corrected entry: Cole says Barbas can use his powers to become the Source, but in the episode "Womb Raider" they established that an aspiring Source needs to lay his hands on the Grimoire to become the source, which was hidden away by Leo in the Andes. (00:19:40)
Correction: Cole doesn't say this. After stealing his powers, Barbas mentions that he can use the amount of power to become the new Source. It isn't proved in the episode that it would actually work, as he never gets to the ceremonial part. Perhaps the Grimoire would have been needed eventually, or seeing the amount of power Cole owns in this season, the Grimoire might have not been needed anymore.
Corrected entry: The only way any of the charmed ones can see the fairies is with the fairy dust, but in several other later seasons and episodes when the charmed ones need the magical community's help they can see the fairies without any help from fairy dust or a spell.
Correction: Originally they didn't know or believe that fairies and trolls existed so they needed the fairy dust or a spell to regain their innocence so they could see them, in later seasons they know they exist so no longer need anything to help them see them.
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.
Womb Raider - S4-E21
Other mistake: Piper tells Page that her doctor told her she probably wouldn't be able to conceive because of scar tissue from blunt force trauma. But Leo has healed Piper, if there was scar tissue after Leo heals, then all 3 girls should be covered in scars.
Suggested correction: They are thrown around quite a bit before even finding out Leo is a whitelighter. Also, he doesn't heal them every time they get thrown or hit in the abdomen. In fact, we usually don't see him heal them at all if they're just thrown across the room or punched in the gut, unless there's a visible wound.
Continuity mistake: When Phoebe starts the fight at the office, she gets pushed and a cut appears on her forehead, but the only thing she collided with was her arm.
Suggested correction: No, she was shoved and hit her head on a filing cabinet. It's shown.
Corrected entry: Phoebe says Piper and Prue were able to defeat Shax without the power of three and Piper's response is it was because "Prue was the strongest." Piper would have no recollection of this event as Tempus reversed time bringing Piper back from the dead in the timeline that she was shot in. The time reversal affected everyone's memory except Phoebe, Leo and Cole who were in the Underworld. (00:14:30)
Correction: I believe that Piper simply meant that statement in general and not because she actually remembered the event. She also doesn't say anything else about the timeline that was altered. In Piper's mind, Prue had always been the strongest of the three of them, because she was also the oldest. Piper and Phoebe use that statement several times throughout the series.
Correction: Also Phoebe was in the underworld and was not effected by Tempus' change, and Phoebe could have told her what happened. I assume they all know what happened before the time change at this point.
Size Matters - S4-E5
Continuity mistake: Shortly after Phoebe frees the blonde girl from the clay, she tells her to run "before Gammill sees [them]." But Phoebe hadn't learned the demon's name at any point. Leo and Piper do find out his name, but not until later. (00:20:00)
Suggested correction: Gamill and Finn are talking when Phoebe is at the house. It may be possible that Gamill's name was mentioned by Finn in conversation.
The Truth Is Out There... and It Hurts - S1-E8
Revealing mistake: When Phoebe asks Piper what she thinks of her boss, you can see that Holly's tattoo has been covered up, because that part of her wrist is darker than her skin. (00:17:15)
Suggested correction: Maybe Holly covered it up with makeup because she isn't supposed to have tattoos for her job? A lot of jobs still don't allow piercings and tattoos today but all those years ago it was even harsher.
There are multiple instances of covered tattoos during the early seasons. I noticed it the most on Alyssa's back tattoo.
Plot hole: Cole explains that the demonic power is driving Karen mad because she is human. Cole later has Paige infected with one to drive her mad. This doesn't make sense since Paige is doubly not human, and shouldn't be driven mad. In fact the Charmed Ones have had demonic powers before and were not driven mad, but instead turned evil.
Suggested correction: They all are human, just not mortals.
Corrected entry: The sisters act as though they have never heard of the evil eye before; but in episode 1-2 'I've Got You Under My Skin' the demon Javna invokes the power of the evil eye to steal youth from women.
Correction: Javna is the Charmed Ones' second vanquish, so it isn't all that unreasonable to assume they didn't know (or remember) that Javna's power was "the evil eye" since they were so new to the craft. They used the Hand of Fatima to vanquish him, and no "evil eye" was mentioned in 1-2 "I've Got You Under My Skin."
Correction: The evil eye was mentioned by Prue when they read the Javna entry.
Continuity mistake: In the recording that Agent Jackman plays for the sisters, the end of the reversal spell is heard "bring her back to me," but when Paige and Piper said it moments earlier, they only said "bring her back." (00:17:45 - 00:19:10)
Suggested correction: They say "bring her back to me" both times.
Size Matters - S4-E5
Other mistake: Since when are managers, on a trial basis no less, allowed to renovate and change the name of a club?
Suggested correction: Piper says in the episode that she allowed him creative control because the club wasn't doing well, and he was well-known to be good at what he does. It's made clear throughout the episode, by way of him telling her multiple times that if she doesn't like it that he'll get rid of it, that she still has full veto power on any changes.
Plot hole: When Yen lo enters the manor in the attic. Where did the water on the floor he comes through come from? Windows were closed, no visible leak, and the sister took precautions to make sure there was no water in the house. Also after he attacks and gets the dragon blade, he exits the house through the sink filled with water. Piper had already said to make sure there was no surfaces of water in the house and had Phoebe and Paige shut the water main off.
Suggested correction: There is a previous scene that shows a visible leak in the windows and an obvious puddle of water on the floor of the attic. This is the same puddle they later enter limbo through. As for the sink, Phoebe (in Paige's body) explains that she had been soaking potion pots and forgot to drain the sink. Turning off the valve wouldn't dissipate water that is already in the sink.
Continuity mistake: The first three episodes have zero continuity when it comes to Piper's love life. In Ep1 "Witch Trial" Piper is hooking up with the guy who is looking at the loan for P3. Then in Ep2 "Morality Bites" she is with Leo (presumably they have secretly been together for months as they discuss their many issues being able to talk when they're both so busy with magic crises and how Leo hasn't figured out how they can be together without clipping his wings). But by Ep3 "The Painted World" Piper and Dan are already together. They has been no discussion of Piper and Leo breaking up and zero mention of Piper and Dan getting together (in fact, the last time we saw Dan in Ep1, he and Phoebe were flirting pretty heavily). I am so confused and I do not at all remember these inconsistencies from when I first watched these episodes years ago. Were these shot and aired out of sequence or something?
Suggested correction: Your last statement is correct, which also invalidates your error. Ep3, "The Painted World" was produced before Ep2, "Morality Bites" but "Morality Bites" was aired first, out of sequence.
Suggested correction: Piper and Dan weren't together in The Painted World, they weren't together until she's a man, baby, a man. When Piper sees his dating tape.
Continuity mistake: In the teaser, when Phoebe physically experiences a past memory, the left strap of her bra is pulled off her shoulder. She then collapses to the ground. When her sisters find her the bra strap is back up on her shoulder. (00:03:25)
Correction: This is a power advancement.
