Continuity mistake: In the teaser, Phoebe has a vision of a murder. When she first sees the shadow of the attack, the assailant is holding his victim down with his right hand while stabbing with his left. Then when the vision focuses on the Medusa head tattoo on his forearm, it is the right arm that is stabbing. (00:04:15)
Continuity mistake: Phoebe is making her coffee and pours cream in. The next scene it's almost overflowing and black.
The Three Faces of Phoebe - S4-E14
Continuity mistake: When Phoebe casts the spell to hear her hearts desire about marrying Cole it conjures old Phoebe and young Phoebe. When Leo, Piper, and Paige enter the room they all room perplexed by who the two people, just conjured, are. If this is supposed to be young Phoebe, wouldn't Leo (who has followed all them their whole lives) Piper and especially Phoebe recognize the younger Phoebe immediately instead of being confused by who she is?
Continuity mistake: When Paige was invisible and Cole watched the blood, there was a large pool of her blood, but in the next shot, the pool of blood was smaller. (00:36:00)
Continuity mistake: The name plate under the photo of Leo at the Veterans Association indicates that he died on November 24, 1942. Paige's research indicates that Nathan and Rick both died on the same day as Leo, but she later finds out that they were buried at the V.A. on November 22, 1942, two days before they are supposed to have died.
Continuity mistake: In this episode, an invitation to Piper is addressed to 1329 Prescott Street. But in episode 1-7: "The Fourth Sister," the Halliwell sisters put up a flyer for their lost cat, and it gives their address as 7571 Prescott Street.
Continuity mistake: While at P3, Leo tells Phoebe that she can't turn into a Harpy just by getting scratched, and when Piper cautions Leo to use discretion Piper raises her left arm to Leo, but in the next shot it's Piper's right arm that's raised. (00:16:05)
Continuity mistake: When Phoebe receives the phone call from her doctor informing her that she is pregnant, she faints and starts to fall to the right. The next shot shows her lying down as if she had fallen to the left.

We're Off to See the Wizard - S4-E19

Womb Raider - S4-E21
Continuity mistake: When Phoebe gets a stomach cramp in Detective Miles' office, she doubles over in pain. In the next shot, she's standing up straighter than she was. Her right hand also moves from the chair in front of her to her stomach. (00:22:55)
Continuity mistake: In the recording that Agent Jackman plays for the sisters, the end of the reversal spell is heard "bring her back to me," but when Paige and Piper said it moments earlier, they only said "bring her back." (00:17:45 - 00:19:10)
Suggested correction: They say "bring her back to me" both times.
Continuity mistake: In the scene where Agent Jackman shows them the file he has on them in their dining room, Paige's left dress strap has fallen off her shoulder in some shots, but in others it's perfectly in place.
