Plot hole: The innocent who gets Piper's powers uses them to freeze Piper and Phoebe. But even though Piper and Phoebe no longer have their unique powers, they are still good witches; they were still able to scry, and we have encountered good witches on the show in the past who had no powers at all. And by the rules of magic within the show, good witches do not freeze.DavidK93
Character mistake: Katya (as Nina) says that Pandora's Box is "a gift the gods gave to Prometheus." But the Box was given to Epimetheus, not Prometheus. Epimetheus ignored the warnings of Prometheus, his brother, and accepted Pandora herself, who bore a box, as a gift from the gods.DavidK93
Continuity mistake: When Piper is talking to Cole, they show the other Piper on the couch. Whenever you see Piper talking, you can see that the other Piper's legs change position throughout the shot. They go from being straight to both legs bent to one leg bent to straight. (00:18:00)
Plot hole: When Paige and Leo are talking in Leo's office at magic school, Paige compliments Leo for being such a good headmaster. She mentions that after being headmistress for a year, it's harder than it looks. If she became headmistress after they killed Gideon (i.e. when baby Chris is born) and she's been headmistress for a year, that would make Chris at least a year old. Chris is obviously not one year old just yet.
Continuity mistake: At the end of the episode it is not Alyssa riding the horse to the café. Alyssa has a tattoo on her right ankle, which when we see when camera pans up the right leg the person riding the horse has no tattoo on the right foot, but when Alyssa rides away you can see the tattoo she has going round her right ankle.julie sheridan
Continuity mistake: In episode 7-7: "Someone To Witch Over Me," Piper is killed by the demon Sarpedon's metallic claw. When the claw strikes her, she falls back with her arms behind her, landing partially on her palms, allowing her to complete the fall by sinking gradually to the ground. Then there is a cut to a closer shot, and we see her fall again. The second time, she falls directly into a more prone position with her arms raised and the backs of both hands facing the ground.DavidK93
Continuity mistake: Midway through the episode, the Seer is looking through the sisters' photo album. Several of the photos actually include everyone who was present for the events depicted, leaving nobody to take the photo. And since the events were shown in various episodes, we know that no photo was taken at those times by any automated method.DavidK93
Continuity mistake: In the second to last scene where Piper tests her powers on the lamp and Phoebe is cleaning, you can see Piper's bra strap when she blows up the lamp but when she turns to face Phoebe its covered. Through out the scene it's covered and exposed without her ever adjusting her shirt.
