Magic Hour - S3-E2
Corrected entry: When the demon with the crossbow fires at the girls, you can hear the sound of arrows coming out of the crossbow. But when he fires at the owl, you can see him aiming and see the owl with the arrow in him, but you never hear the sound of it firing.
The Power of Three Blondes - S6-E4
Corrected entry: The sisters couldn't touch the Book of Shadows after the Stillman sisters stole their identities, so how come later in the episode they hold the book to say the spell to get back their powers without casting a spell to get back their identities?
Correction: After the Stillman Sisters had the argument, they lost the trust of the Book and it returned back to the Halliwell Sisters. This is shown during said argument when the symbol on the cover of the book split apart. The spell they recite at the end was merely to get their identities and powers back.
Corrected entry: In this episode when Phoebe and Piper have left the car to go and find Miles (to stop him dying), the second time after past Piper has warned present Piper to go right not left, Phoebe's shoes change from what appear to be black boots or high-heels to flat beige knee length boots.
Correction: Duplicate Entry - the other one explained it better.
Used Karma - S6-E13
Corrected entry: In this episode Paige is wearing a strappy top that shows her back, on which you can see a tattoo of a woman. I'm pretty sure that was never there before in any of the other episodes/series. (00:10:50)
Correction: This is a mistake, not trivia.
Corrected entry: During the show up until now, they make it clear Prue is 35-37. But when Piper and Paige visit Prue's grave, it says 1970-2001, therefore making her only 31.
Correction: In the season one episode "Dream Sorcerer", a nurse in the hospital states that Prue is 27 when she is brought in after the accident. This is consistent with her grave saying that she was 31 when she died.
Corrected entry: In the first season, witches aren't allowed to know they have a whitelighter, but later in the seasons, all Leo's witches call for him.
Corrected entry: Leo has always stipulated that he cannot heal himself, but when he gets stabbed by Rick his wound instantly heals itself.
Corrected entry: When Phoebe and Piper were trying to help Paige use her powers, they said that she should wave her arm at the candle because thats what Prue did. But when Prue got her powers, she controlled her magic with her eyes not her arms.
Power Outage - S3-E7
Corrected entry: Prue says that they should practice their demon counter attacks so that they can get a piece of Balthazar's flesh, as it "might be helpful for the potion". But in every future episode they say that the flesh is necessary for the potion.
Correction: It was their first time making that kind of potion. They knew in the future that is was the only one that would work.
Corrected entry: In the first shots of this episode, they show the ghost of Alcatraz and a soul collector. They failed to take away the shadows of both the ghost and the soul collector. There's a scene where a crowd of people are looking into the jail cell that the ghost and the soul collector are in. It shows no ghost, no soul collector and, importantly, no shadows. The next scene shows the ghost and the soul collector, and miraculously they have shadows. (00:02:35 - 00:05:00)
Correction: It's showing what the cell looks like to ordinary people: empty. But then it shows the TV viewers that there really is something in the cell.
Corrected entry: Throughout season 6 Chris continually refers to his memories of the Charmed ones in the future (using the words "the three of you", yet in "Oh My Goddess" he tells Phoebe that if he hadn't come back, Paige would have been killed that day. So how can he have memories of the three of them when Paige died before he was born?
Correction: You've answered your own question: "if he hadn't come back, Paige would have been killed that day." He came back, so she wasn't killed that day, so he has memories of her from the future.
Corrected entry: In this episode Paige is assigned Sam, her father and Patty Halliwell's former whitelighter, as a charge but in the episode P3 H20 we find out that Sam clipped his wings - "Piper: Sam was mum's whitelighter?" "Leo: Emphasis on was. When your mom died, Sam clipped his wings. He's mortal now, but once, yeah he was a whitelighter. He looked after your mother"
Correction: He states in this episode that after he died for the second time after being made mortal, the elders made him a whitelighter again.
Corrected entry: Tuatha says that there is no such thing as a courage potion, and when the girls search the book of shadows they also say that there is no magical way of giving confidence. But in episode 1-11, 'Feats of Clay', Piper casts a confidence spell on Doug so he will stop breaking everything in the restaurant.
Correction: Given that the confidence spell on Doug backfired and turned him into a conceited ass, they likely discounted that spell right away.
The Truth Is Out There... and It Hurts - S1-E8
Corrected entry: The morning after Prue says the truth spell, Piper is wearing a green shirt with a necklace, but when she goes to Quake, she is wearing a white top with a necklace, and when Piper is back at the manor, she is wearing the same green top, but without a necklace.
Correction: Not really a mistake. Many people have work clothes and casual clothes that they change during the day, especially in the service industry.
The Truth Is Out There... and It Hurts - S1-E8
Corrected entry: When the demon approached Tanya in the elevator, there were several other people in there with them. The demon immediately started talking about how hard it was to find her, and how she was never alone - which she still isn't, but he doesn't mention that. From Tanya's facial expression, she thought he was very creepy. We cut to Phoebe and Prue trying to get to Tanya before the demon can kill her. Then we see the demon dragging Tanya through the parking lot. But they were in an elevator full of people, and he was some sort of masher, at the very least. Plus, she was in the middle of work, transporting a loaded dolly, so it's extremely unlikely that he could have lured her away. How did he manage to drag her out and into the parking lot?
Correction: Intimidation? A spell? A special power he possessed? There are enough reasonable possibilities to prevent this from being a mistake.
Something Wicca This Way Comes - S1-E1
Corrected entry: In the first episode when Phoebe is in her room, you can see that the tattoo on her shoulder has covering makeup on it, but not enough to completely cover it. It's not covered up for the rest of the series.
Correction: People cover tattoos with makeup all the time. It's possible she wanted to cover it but later decided she didn't care.
Corrected entry: The family tree was written in the same handwriting, and that includes that Grams died, so that would have meant that either Prue, Piper or Phoebe had written the family tree.
Correction: There was someone else that was around the entire time. Leo.
Corrected entry: In this episode, the Charmed Ones travel into the past, to 1975. Prue explains to Piper that one of the reasons Patty became a waitress was because, "With Dad gone, she had to pay the bills somehow." However, Patty was in the earliest stages of her pregnancy in this episode, while episode 1-3: "Thank You for Not Morphing" established that Victor didn't leave the family until after Phoebe was born.
Correction: When Barbas makes the girls relive their worst memories, Piper's is her father leaving "for the last time," implying that Victor left and came back several times before leaving for good. Given Victor and Patty's rocky marriage, this would have been another of those periods when he was gone and Patty had to make ends meet on her own.
All Hell Breaks Loose - S3-E22
Corrected entry: In the emergency room after Piper has been shot, it is clear to see that Piper's bullet wound is a through and through, meaning the bullet went in and out, BUT if it did, that means that it should have hit Prue after exiting Piper because Prue was right in front of Prue when the shot was fired.
Sight Unseen - S3-E5
Corrected entry: When Phoebe, Piper and Prue get home to find the AC on, Phoebe said that every window in the house was open, but she was downstairs so she didn't know if the windows upstairs were open.
Correction: When it's that cold in my house and I see that a lot of windows are open, it's like a figure of speech "all of the windows in the house are open." Phoebe might not have actually KNOWN at that time that EVERY window in the house was actually open.
Correction: When he fires the arrow at the owl, you can hear both the arrow being fired and it hitting the owl.
