Visible crew/equipment: Just after Paige orbs into Phoebe and Cole's hotel room, a boom mic can be seen at the top of the screen.
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.
Other mistake: This entire episode the ghost brothers whine that Leo is responsible for them dying and he left them to die, even Leo believes this. It makes no sense. As we see in the flashback even if Leo stayed to help they were blown up moments later and still would have died.
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
Visible crew/equipment: After Phoebe tells Cole she's pregnant she leaves in the elevator, and when it cuts to Piper, Paige, and Leo we can see the crew's grey mat on the floor under Piper and Paige, then in two following shots (from the same angle) the red T-mark is visible on that mat, at Paige's feet. (00:07:45)
We're Off to See the Wizard - S4-E19
Continuity mistake: When Leo arrives to tell the sisters about the wizard, Phoebe's hands change position between shots. (00:29:55)
We're Off to See the Wizard - S4-E19
Continuity mistake: In the scene where we first see Phoebe and Cole when she's about to leave the apartment, you see she is wearing gold and white high heels but as soon as she reaches the elevator she's wearing black boots.
We're Off to See the Wizard - S4-E19
Other mistake: Leo tells Phoebe that fire throwing is an upper level demon power, but we know Phoebe had that power in her past life, Piper even reminds her of this earlier in the episode.
Visible crew/equipment: During Cole's meeting with Dane and several other demons, just as Dane begins to talk about Gregory Conroy being a probation officer to juvenile offenders, the yellow T-mark is visible on the floor near the actor's feet. (00:06:00)
Womb Raider - S4-E21
Continuity mistake: When Phoebe talks to Morris in Detective Miles' office, her hands change position instantly between shots. (00:22:45)
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)
Womb Raider - S4-E21
Visible crew/equipment: While Piper, Phoebe, and Paige are in the magical cage, the Dark Priest, the demons, and the Seer are all killed/vanquished, then when Piper kicks open the cage the sisters walk out, and we can see the black mic transmitter attached to Phoebe's waist, at her back on the right. (00:38:40)
Womb Raider - S4-E21
Other mistake: Piper tells Page that her doctor told her she probably wouldn't be able to conceive because of scar tissue from blunt force trauma. But Leo has healed Piper, if there was scar tissue after Leo heals, then all 3 girls should be covered in scars.
Suggested correction: They are thrown around quite a bit before even finding out Leo is a whitelighter. Also, he doesn't heal them every time they get thrown or hit in the abdomen. In fact, we usually don't see him heal them at all if they're just thrown across the room or punched in the gut, unless there's a visible wound.
Visible crew/equipment: When Phoebe's assistant walks into the office carrying a tub of mail for Phoebe, the shadows of the boom mic are visible on the wall over her and the TV. (00:00:25)
Other mistake: After they talk to the Angel of Destiny for the first time, they send Leo to ask the Elders if he is legit. After Leo leaves they find out about Agent Jackman, and the following events unfold. After Jackman busts them Piper calls for Leo and tells him "It's OK, you can orb" and he appears asking her "What about Agent Jackman?" Except that Leo was gone before they found out about him and the girls hadn't told Leo yet that he even existed. (00:09:09 - 00:21:58)
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.
Revealing mistake: In the teaser, when Leo levitates to hang a picture, he has a major wedgie and the ankles of his pants hike up to mid-shin due to the harness that is used for the levitation effect.
