Brain Drain - S4-E7
Revealing mistake: When the Chameleon Demon changes from a lamp to a demon he throws Piper and Phoebe with Telekinesis but Piper looks to the right before he motions the toss. (00:03:05)
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.
Other mistake: Grams says that if she died the girls would automatically get their powers; but they got their powers 6 months later and Phoebe had to read from the book of shadows first. Not really automatically.
Continuity mistake: In the season 2 finale the council has five members and yellow robes, in this episode they're now called the triad and there are 3 members in red robes (changed to black robes with inverted pentagrams in later seasons).
Continuity mistake: Near the end of the episode Piper is talking to her sisters in the parlor with her watch is on her left wrist and a bracelet on her right wrist. She goes upstairs to her room to cry and her bracelet and watch have switched places. (00:39:05 - 00:40:00)
Continuity mistake: When Phoebe first meets and talks to Nathan in the hospital, she has no ring on her right hand in shots showing her face, but in any shots from behind her she has a ring on. The ring appears and disappears between transitions during their conversation. (00:07:50)
Other mistake: When Paige is talking to her charge in the club the same guy walks behind them twice in the scene. (00:14:00)
Repo Manor - S8-E13
Other mistake: When Piper blows up the dollhouse, killing Pilar, Phoenix and Patra, you can hear the sound effect of telekinesis, despite Piper's power being molecular combustion.
Deja Vu All Over Again - S1-E22
Continuity mistake: At the end of the episode, Phoebe's hairstyle changes from tied back when talking to Piper in the kitchen, to down and re-done in the time from the kitchen to the front porch.
Audio problem: When Evil Prue flings Piper and Phoebe back, you see Piper hit a pillar, but with Phoebe's voice of pain. When we see Phoebe fall behind a structure, we hear Piper's voice of pain.
Audio problem: When Piper, Paige and Phoebe run up to the attic to run from Shax, Piper says that they're about to find out if Paige is their sister, her mouth is shut when she is supposedly saying the sentence.
Other mistake: In the kitchen scene, Phoebe adds a mix to a pie crust but puts an empty crust in the oven. (00:04:10)
Wicca Envy - S1-E10
Continuity mistake: At the beginning of the episode when Piper hides her sisters from Leo she has the shirt with the buttons closed, but between that scene the shirt is not closed. (00:01:05)
Continuity mistake: When the sisters first see the lady in the lake, the demon off to the side throws a knife into her back, but the knife hits completely straight, as it would if the demon had been directly behind her.
Other mistake: After Sam uses the powder on the sisters, erasing their memories, they're visited by Leo who starts to say "he must have gotten the powder" and one of the sisters finishes with "our mother." But in a later episode we learn all white lighters have this powder.
The Courtship of Wyatt's Father - S6-E16
Revealing mistake: Just after Piper and Leo are taken away, Paige orbs down to the ground and runs up to Pheobe, places her hand on her, and shows a blood-covered hand showing that Pheobe's been injured. But before it's shown, while Paige is running up to Pheobe, you can see Paige deliberately keeping her hand closed and facing away from the camera, because it's already there when she orbs down.
Continuity mistake: When the main Calloway throws the clear bottle with the green potion at one of the enemies, the shot cuts and it's now become a white bottle.
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.
Revealing mistake: When the pawn shop owner jumps through the glass door, it is painfully obvious that it's a stunt double.
Revealing mistake: When Phoebe opens the cupboard and the human pig falls on top of her, you can see that it's a stunt double in the far shot.
