Continuity: When Piper and Prue are standing in the bedroom with Charlotte, Prue's hand moves from covering her mouth in one shot, to being by her side in the next.

Factual error: When developing a photo it's first put into a developer chemical, which shows the picture up, then a stop, which stops it from developing anymore, then a fix which "sets" the photo. But in the basement, Prue puts the exposed photo into a tray with chemicals in it where it starts to develop, then into a second tray where it develops fully.

Continuity: When Prue was talking with the shut-in and the security guard comes up and knocks on the door you can see the the chain is on the door. When he knocks again and says he is coming in and tries to open the door the chain is off.

Audio problem: When Prue is at the dentist, she grabs a guy and he says, "What, what did I do?" to his girlfriend, but his lips do not move.

Revealing: At the end when Prue is fighting the demon you can tell she is holding on to her safety harness when she is in the air kicking him.

Continuity: When Prue is in the basement with the priest she has curly hair, but when she comes upstairs to vanquish Vinceres it is completely straight, but she definitely didn't have time to straighten it.

Revealing: When Astral Prue kicks Leo/Balthazar in the face during the training drill near the start of the episode, her foot misses his face yet he still reacts as if hit.

Continuity: During the training drill, Piper fumbles for a knife on a table in front of her. In the shot of the table, she loses hold of the knife as she pulls her hand up, but when we cut to a long shot, it is back in her hand.

Other: Alyssa's tattoo is visible when Phoebe leaves Cole's apartment after she fought with her sisters.

Revealing: When Phoebe throws the potion at Cole's coat, the vial doesn't shatter, even though it sounds like it. Watch closely, and you'll see the purple, unbroken vial bounce off the coat and away out of shot without any of the potion touching the coat.

Other: When Piper puts the Belthazor flesh into the Belthazor vanquishing potion, she is the only one that gets "blasted" back even though she is the one standing farthest away from the stove and the potion.

Revealing: When Cole / Belthazar grabs Phoebe to use her as a hostage, you can see, very obviously, that he doesn't pull her. Phoebe actually steps in front of him willingly, despite the look of fear on her face.

Plot hole: On the Balthazar page in the book of shadows it says that there is no way to vanquish him, but on the opposite page is a vanquishing potion.

Revealing: Prue knocked Piper unconscious in the cat fight (after the Coyote Dance), and asked Justin to carry her to the car. But when he is apparently lifting Piper up from the floor, you see Piper standing up by herself.

Other: At the beginning of this episode, Tara and Kierken are arguing and Kierken says that he could always "suck you into your little mixing bottle and start again." Then Tara says that "she has a better idea," and then she stabs herself. The life essence automatically flows out of her but the knife was still in her body. Later, the possessed business man stabs himself in front of Piper and she kneels down to see if he was okay and the essence flew into her, without the knife being removed from his body. At the end, when Leo comes down after Prue stabs the possessed Piper, he kneels over her, but the essence does not flow into him. It only flows into him after he takes the knife out of her body.

Revealing: After Phoebe has her premonition in the mausoleum, she wipes away the dust from the crypt to reveal Cole's father's name. Just BEFORE they show her wiping the dust away, you can see the letters in the shot of her leaning against the crypt.

Visible crew/equipment: When Prue and Phoebe are trying to pull the girl out of the ice-cream truck, in one brief shot, you can see the wires holding the girl up.

Plot hole: In episode 1-3, "Thank you for not morphing", Victor mentions that he wasn't sure that his daughters would be witches - only that there was a possibility. However, this episode indicates that Victor did know about his daughters' powers before he left the family.

Continuity: When the girls are saying goodbye to their father, Phoebe hugs him around the neck, then lowers her arms while they talk. When her father says "About anything," her left arm jumps back up to being around his neck, and in the next shot, it's down at the side again.

Continuity: When Prue and Phoebe first enter the ice-cream van, we are told that their powers don't work in this dimension, but a few minutes later, Phoebe gets a premonition from the swingset - if their powers really didn't work, she wouldn't have been able to.
