Visible crew/equipment: In the scene where Prue comes home and finds Andy inside the manor. There is a shot where if you look behind Andy's shoulder you can see half of the body of the director in the background in the observatory room sitting in a director's chair. (00:16:00)
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. (00:25:20)
Continuity mistake: When Phoebe and Cupid visit the memory of Phoebe revealing she is a witch to Dex, past-Phoebe has her hands down by her sides, but then her left hand suddenly jumps to her purse strap. Not only that, but in the original episode ("Rewitched"), Phoebe's hand remained on her purse strap the entire time. (00:11:05)
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. (00:06:45)
Continuity mistake: When Piper is talking to Cole, they show the other Piper on the couch. Whenever you see Piper talking, you can see that the other Piper's legs change position throughout the shot. They go from being straight to both legs bent to one leg bent to straight. (00:18:00)
Revealing mistake: In the beginning of the episode, Yenlo and Anling are fighting with swords. After Yenlo says, "I'm going to kill him, Anling. And then I'm going to kill you," Anling stabs him with her sword. Yenlos' wound is very bloody, but there is no blood on Anling's sword at all. (00:04:25)
Continuity mistake: At the end of the episode it is not Alyssa riding the horse to the café. Alyssa has a tattoo on her right ankle, which when we see when camera pans up the right leg the person riding the horse has no tattoo on the right foot, but when Alyssa rides away you can see the tattoo she has going round her right ankle.
Continuity mistake: When the spider demon cocoons Piper, Paige throws a blue potion (the vanquishing potion) at her, Chris catches it and jumps over the couch, knocks Paige to the floor and Phoebe kicks Chris. The potion falls out of Chris hand and rolls into Paige's open hand, it has now turned yellow (the antidote) Paige grabs it as she stands and throws it at the spider demon again and it has now turned back into the blue potion.
