Other mistake: At the end, it shows the Charmed Ones orbing out of the trial, but Chris and Leo never leave. Right after the Charmed Ones orb out, Barbas begins discussing his evil plans with Gideon, so wouldn't Leo and Chris find out that Gideon is plotting against them? After they talk, the camera pans out and Chris and Leo are not there. I guess they just forgot to put in the scene where they leave.
Continuity mistake: Just after Olivia has killed Mr. Montana and everyone goes running up to see what has happened, Phoebe waves to Paige through the window of the Calloway's house which is shown to be right next door to the Montana's house. Earlier in the episode it had been established that they lived across the street.
Continuity mistake: When Gideon warns Sara not to use magic to put the books in the library back on the shelves, her arms are at her sides. A second later, the shot changes to over her shoulder as Leo orbs in and she has a nearly full armload of books. (00:08:55)Captain Defenestrator
Continuity mistake: When Phoebe is walking the Dwarf to the door after finding out Piper pulled the sword from the stone, he steps outside and goes into fast-forward, then stops and goes back to normal speed as he sniffs a flower. During this, in the background, you can see Phoebe, who freezes the whole time. (00:18:40)
Continuity mistake: When the spider demon cocoons Piper, Paige throws a blue potion (the vanquishing potion) at her, Chris catches it and jumps over the couch, knocks Paige to the floor and Phoebe kicks Chris. The potion falls out of Chris hand and rolls into Paige's open hand, it has now turned yellow (the antidote) Paige grabs it as she stands and throws it at the spider demon again and it has now turned back into the blue potion.julie sheridan
Continuity mistake: When Chris orbs to the manor after Paige has returned home, his hair is brushed to lay mostly flat and behind his head, with a part on the left side of his scalp. When he comes into the kitchen shortly thereafter, his hair is shaggy and unkempt, with a part in the middle.DavidK93
Continuity mistake: When Piper, Paige and Phoebe are having a food fight, Piper freezes the cake, then she throws it at Paige who suddenly has a mysterious stain on her top. Then Piper has orange food on her hands even though she hasn't touched anything orange, and the stain on Paige's top has gone.
Other mistake: In previous episodes it is stated that good witches don't freeze. But after Piper has been decapitated and her head is placed in the manor, one of the students freezes all the kids by tapping into Piper's freezing power. The kids are all good witches so they should not have frozen.
