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: 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.
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)
Correction: This is a power advancement.
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.
Corrected entry: When Phoebe picks up the cordless phone to call Paige before the Shocker Demon attacks for the first time, the cordless phone is white but then after the attack, when the cordless is on the floor, it's black.
Corrected entry: Why did Phoebe have to write a spell to vanquish the warlock in this episode? When they have vanquished warlocks before they used the power of three spell, "the power of three will set us free". (00:16:55)
Correction: Spells work best when written to deal with a specific demon or type of demon. There are many demons who they write spells for, and others they simply use what worked for their ancestors who then wrote the spell in the Book of Shadows.
Correction: There was actually something in their contract about not having to say the Power of Three spell too many times per season, or something to that effect. I can't remember the exact way it was written, but neither the writers nor the actresses wanted to say that spell all the time. So they only saved it for dire situations, instead of just using it to vanquish everything (because technically, they could've vanquished every demon, warlock, etc. with that spell).
Corrected entry: The seer tells Cole that his son will be a force of good magic unless he marries Phoebe in a dark ceremony, but in 4-1 "Charmed Again" Cole and Leo tell them about the 48hr window where a new witch gets to choose whether they are good or evil.
Correction: The seer was predicting the future of the child they would have if the dark wedding was not performed. Since the child would be raised as a witch, without the dark ceremony, the 48 hour window relating to a witch just finding out about their powers would not apply.
Corrected entry: After Cole tells Leo, Piper and Phoebe the source has surfaced, Piper asks Leo if he can "sense Paige". Leo replies, saying no, "she's too new". But aren't white lighters meant to help witches who are just coming into their powers, which is exactly what Paige is doing?
Correction: It is also stated through out the entire show in various episodes that if a white lighter hasn't formed a bond with his new charge they can't sense them. For example when Leo first came around the charmed ones it was to get to know them and form that bond. This also occurs with Paige's new charges.
Corrected entry: Piper convinced Paige that they should use their powers to make Andrew confess to murder. Paige wonders why it's okay to reveal their powers to a mortal, and Piper and Leo explain to her that it's all right to use their powers on a mortal because they're trying to help an innocent. But in episode 2-19: "Ex Libris," Prue wanted to use a truth spell to force the pawnshop owner to confess to murder, and Phoebe pointed out that it is an abuse of their powers to punish the guilty.
Correction: There's a difference between helping the innocent and punishing the guilty. Sometimes, helping an innocent will inadvertently also punish the guilty, but the main goal for them is to stop pain and suffering happening directly to an innocent.
Corrected entry: The Seer tells Cole about the importance of the upcoming "Harvest Moon." But this episode aired in mid-March, while the Harvest Moon is the full moon closest to the autumnal equinox. The full moon closest to the vernal equinox is known as the Worm Moon. (00:02:55)
Correction: Real time is not taken into account within the fiction of the show, so it doesn't matter what the actual date is when the episode aired.
Brain Drain - S4-E7
Corrected entry: Right after Piper comes out of her crazytown adventure, she comes down the stairs in completly different clothes and hairdo than she went in with.
Correction: This is not true, Piper has the same hair and same clothes.
Corrected entry: In episode 3-13: "Bride and Gloom," Prue was married to a warlock in a dark ceremony, causing her to almost immediately become evil, and this caused her sisters and the Book of Shadows to become evil as well because all of the magic is connected. In the fourth season, Phoebe married the Source in a dark ceremony, and did eventually herself become evil (as evidenced by her ability to touch the Grimoire), but the evil did not extend to her sisters or the Book. So the mistake is twofold: Phoebe did not immediately turn evil, and her sisters and the Book never turned evil.
Correction: The reason evil traveled from Prue to her other sisters and to the book was because of specific magic that the dark priestess performed. The marriage in itself wasn't enough to turn them evil, it was the ritual she performed in addition to the marriage.
Corrected entry: When Nathan and Rick throw the knife and stab Leo after Leo pulls the knife out he heals himself, However throughout the whole series Leo makes it clear that Whitelighters can't heal themselves.
Correction: It's been noted throughout the series that the only way to kill a whitelighter is with the poison from a darklighter's arrow. Leo can't heal himself when injured from a darklighter, but can heal himself from other wounds.
Wait that still doesn't make sense. In the episode where Piper and Phoebe find out about Paige's existence, Leo gets injured and Phoebe asks him why he cannot heal himself and he responds "3 years together and you are just now asking these questions?" Piper is icing his neck for him. That was another wound (not from a darklighter) and he was not able to heal himself then. I think the writers just needed an easy way to show the ghost brothers that Leo was still alive and that he is a whitelighter that cannot die.
Brain Drain - S4-E7
Corrected entry: If the vanquishing spell doesn't work in the Halliwell Hospital place, then the Power Relinquishing Spell shouldn't work either.
Correction: The reason the vanquishing spell didn't work was because the spell was to vanquish the Chameleon demon. But it was The Source disguised as the Chameleon demon, so it is obviously not going to work.
Corrected entry: During the show up until now, they make it clear Prue is 35-37. But when Piper and Paige visit Prue's grave, it says 1970-2001, therefore making her only 31.
Correction: In the season one episode "Dream Sorcerer", a nurse in the hospital states that Prue is 27 when she is brought in after the accident. This is consistent with her grave saying that she was 31 when she died.
Corrected entry: Leo has always stipulated that he cannot heal himself, but when he gets stabbed by Rick his wound instantly heals itself.
Corrected entry: When Phoebe and Piper were trying to help Paige use her powers, they said that she should wave her arm at the candle because thats what Prue did. But when Prue got her powers, she controlled her magic with her eyes not her arms.
Corrected entry: After Glen finds out about Paige being a witch he jokes about calling off the tabloids. Piper freezes him and says, "you wouldn't find it so funny if you'd lost a sister that way". But time was reversed and the sisters' magic was never revealed, Prue was killed by Shax. Also Piper had no memory of that day, when time was reversed she had no idea why Phoebe wasn't there, so why would she blame Prue's death on that?
Correction: Prue would never have died if they hadn't been exposed to the media. Without the exposure, time wouldn't have needed to be turned back. As for Piper not knowing about the exposure, Phoebe, Cole, and Leo were in the Underworld and therefore not affected by the time change. They would have filled her in on how and why Prue died.
Corrected entry: Paige apparently only gets her witch powers in this episode, but that doesn't fit with what we know of magic from the rest of the series. If Paige was born a witch, she would have always had her witch powers unless they were bound (which we know they weren't since she would have also lost her orbing ability until now), so she should have been telekinetically orbing things her whole life.
Corrected entry: When the Source, as Shane, stabbed Cole, it was broad daylight. The sisters and Leo didn't find him to heal him until late at night. This means that Cole's semiconscious, bleeding body was lying next to a city sidewalk for half a day without being noticed by anyone.
Correction: It is possible that no one saw him, this is not a mistake.
Corrected entry: When Paige decides to use magic to show Glenn that she really is a witch, she casts a spell that is supposed to "expand his imagination," but instead makes his body able to expand and contract like elastic. But why would Paige cast an unfamiliar spell on Glenn, instead of just using her orbing talent to provide quick and obvious proof of the reality of magic?
Correction: Because by "expanding his imagination" he will be more likely to believe and accept what she is telling him, while simply orbing might make him freak out and not be able to accept it.
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.
