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.

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.

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.

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.

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.

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.

Deliberate "mistake": When Piper froze the demons (near the wrestling) one of the demons moved when she froze him.

Continuity: When Rasputin first lay on the couch, he was at the end of it, but two shots later he was suddenly in the middle of the couch.

Continuity: Phoebe's hair got dyed back to a dark brown, but later on in this episode, her hair became blonde again, but she didn't dye it.

Revealing: When Prue talks about her relationship with Jason near the beginning of the episode, she says that she finds him to be very predictable, lacking in mystery or "savoir-faire." That doesn't make sense, though, as "savoir-faire" means "know-how." She probably meant "je ne sais quoi," that is, "I know not what."

Continuity: When Cole and Prue are about to shimmer to the other plain to find BO, Cole's face has not been shaved. But when they reach the other plain, his face is cleanshaven.

Plot hole: Unless someone else cleared out Cole's apartment, Cole/Belthazor would have been careful and smart enough not to leave behind the altar for exactly what happens in this episode.

Continuity: When Piper is sitting with Leo on the tailgate of the SUV, when shown from the front her hair is in front of her shoulder and ear, but from the back we see it tucked behind her ear. This switches constantly throughout the scene.

Continuity: When Prue talks to Piper after stopping her phone conversation, she tells her that "the Sin Balls work a lot faster than [they] thought. Once infected, the victim only has a few hours before it drives them to total self-destruction." However, this is almost verbatim what was written in the Book of Shadows. It could be easily read by the viewing audience when the book entry was shown. So all three sisters should already know this.

Other: At the start of the episode when Prue and Phoebe are walking down the street (just before they find the box), the person with the green jacket on (in the background) reaches into the homeless man's hat and just "scrapes" the bottom of it. Not putting any money in, or taking any money out - a completely pointless action.
