New this month Continuity mistake: In the episode "P3 H20" we learn that Patty died because of the Water Demon, which is why Prue is afraid of water. However in this episode we are told that Patty was killed by the Sea Hag, and that's why Piper develops her demon fear upon becoming pregnant.
Continuity mistake: In 3-5 Sight Unseen, we can clearly see Cole turn the air conditioning very cold and open all the windows so that the Prue, Piper and Phoebe can see the invisible demon, and in season 2 when Prue is turned into a man Phoebe asks "did you fix the air conditioning?" But in this episode Phoebe asks Piper why they have never invested in air conditioning.
Plot hole: In episode 1-2 ("I've Got You Under My Skin"), Alec buys Phoebe a martini at Quake. but then in episode 5-11 ("The Importance of Being Phoebe"), Cole tells Kaya that Phoebe doesn't drink. Then, in episode 5-17 ("Lucky Charmed"), Jason buys Phoebe a "Martini, Dirty" at the end.
Continuity mistake: When Paige follows Phoebe into the kitchen and is trying to convince her that she is telling the truth, Phoebe's right earring is missing in the shots showing both women, but it is there when the shot changes to close ups of Phoebe. It is an awfully large earring to be hidden by her hair in the two-shot.
Plot hole: When Phoebe and Paige are in Piper's memory of her wedding, the warlock steps on the cake topper, crushing it. Piper feels a pain in her heart, and it shows it disappearing in the future, leading you to believe that it will have some significance. Yet, it is never brought up again in the series.
Plot hole: Phoebe says to Paige that she didn't know that Kit was their familiar, that she was just some cat that kept hanging around on the porch. But they learned that Kit was their familiar in episode 3-17 'Pre-witched', and they also said that Kit is male, unlike the woman in this episode.
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.
Continuity mistake: In episode 3-9: "Coyote Piper," Piper danced sexily on the bar while the song "Unbelievable" played. She danced only to the one song before her sisters pulled her off the bar. In this episode, Phoebe and Paige physically enter Piper's memory (magically enhanced for accuracy), and a different song plays during Piper's dance, despite it being the exact same video footage.
Continuity mistake: In the episode "A Witch in Time," when Phoebe and Piper are going to Miles' work to get him for the first time, Phoebe runs up the steps to his work and she is wearing leather boots with a skinny heel. Then, when she and Piper are running to where the police shoot-out is, Phoebe is wearing tan Ugs. Then, when they get there and Piper freezes the scene and Phoebe is getting the bullets out of the air, she is wearing the leather boots again.
Deliberate mistake: In this episode Wyatt has his wiccaning. After all of the vanquishing is done with the Necromancer, it's finally time for the wiccaning and the spell that is said is this: "I call forth from space and time, Matriarchs from the Halliwell line, Mothers, daughters, sisters, friends Our family spirit without end, To gather now in this sacred place And help bring this child to grace." In this spell it is said to bring forth "daughters and sisters" from the Halliwell line, Prue died in the third season and this is now the fifth season, shouldn't she have been summoned as well to bring her nephew Wyatt to grace?
Plot hole: The Sea Hag says at the start of the episode to Mylie that as an immortal being, only she can place the augur shell over her heart to give up her life. But at the end of the episode Necron magically places the shell onto Phoebe and it nearly sucks the life out of her.
