Continuity: When Phoebe goes to get her palm read, Madame Theresa draws lines on her hand. But when she first enters the room and sits down the lines are already visible on her hand, before they have been drawn there. (Time)

Plot hole: 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.

Plot hole: When Phoebe had her premonition of Lydia being attacked by Cree, why didn't she immediately warn her? Lydia is a Gypsy high priestess, which Phoebe knows because she just saw Lydia perform a religious ceremony, and she also knows from the previous events in the episode that Gypsy elders are aware of Wiccan magic. But instead she said nothing and waited to talk to her sisters before doing anything about the premonition. So although they were able to save Lydia, she wound up being needlessly attacked and injured. Submitted by DavidK93

Plot hole: There are many references in this episode to Phoebe using a power-stripping potion on Cole. But it wasn't Phoebe who used the potion on Cole; it was Emma, the fiancée of one of his victims. Submitted by DavidK93

Plot hole: 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.

Continuity: 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 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. (Time)

Continuity: When Phoebe cut Cole in 'A Witch's Tail' the blood was acidic and melted through the letter opener, but in this episode the blade was complete and had drops of blood on it. (Time)

Continuity: When the Charmed Ones decide to try to vanquish Cole, Paige says that the newest potions they mixed should work, since they're "at least as strong as the ones [they] used on the Source." But they never used any potions that had an effect on the Source. (Time) Submitted by DavidK93

Continuity: When Paige and Phoebe are sitting at the bar at the beginnning of 'Sam I Am' their arms change positions between every shot. (Time)

Revealing: When Kaya throws the knife at Phoebe watch in freeze-frame and you can see that for the shot from behind her there's no knife in her hands. (Time)

Plot hole: When Cole and Kaya are taunting Piper and Paige about the fact that they now own the manor, they hold the deeds out in front of them laughing for a good 5 seconds. Did they, and more importantly did Paige herself, forget that she can orb things to her? She could easily have summoned the deeds and orbed out of the house before Cole could stop her. (Time)

Continuity: Paige's green top that covers her black t-shirt constantly changes from being on her shoulder to off, particularly in the police station scene. (Time)

Plot hole: Close to the end of the episode, when Phoebe is going into the house pretending to be Kaia pretending to be Phoebe, Paige and Piper tell Phoebe that the demon twirls her hair, a lot. Cole also brought this to our attention much earlier in the episode. Phoebe says she's got it, and goes into the house. Paige had indicated that the problem with getting into the house was that there's a "whole load of demons" and a force field. Phoebe was to impersonate Kaia in order to get past all of these defenses. But through out the whole time she's in the house, Phoebe never twirls her hair. (Time)

Continuity: Although the actress has changed, Piper's doctor appears to be the same character as Eva, the shuvani, Paige even says, 'we saved her shuvani tribe'. But throughout this episode they call her Eve. (Time)

Continuity: 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. (Time)

Plot hole: In 'Centennial Charmed' Paige orbs to another reality where she loses all her powers. Leo tells her the this is because she was never called as a witch in this world, but Paige had most of her powers before she was called because of her whitelighter blood, so she should retain these. Leo says that Paige has assumed the life of this reality's Paige, but then adds "...or at least the life she would have lived if she hadn't been killed". If alternate Paige had lived she would have had Whitelighter powers, even if she didn't know about them, so our Paige should also have them. (Time)

Continuity: Paige's headstone reports her year of birth as 1975. But in episode 4-2: "Charmed Again, Part Two," Paige spoke with the nun to whom she was given as an infant on August 2, 1977, and Paige is always described as having been "given up at birth" by Patty and Sam. (Time) Submitted by DavidK93

Plot hole: Paige realises at the end that time went on in her own dimension at the same time as it went on in the alternate reality, and Piper calmly comments "Oh there you are. We were wondering" or words to that effect. Paige had been gone over a day and Leo wouldn't have been able to sense her across dimensions. Weren't Phoebe or Piper the least bit worried about her?
