Something Wicca This Way Goes - S7-E22
Continuity mistake: The hole where the demon throws an energy ball through the roof is gone when the doors close.
Plot hole: When the man and woman receive Piper and Phoebe's powers, the lady freezes the man and Phoebe due to fear, but good witches don't freeze, so if Phoebe froze (which she shouldn't have due to only her active powers lost) then why did the man? If he had Phoebe's powers then he isn't mortal and therefore should not freeze.
Show Ghouls - S7-E15
Plot hole: When Leo tells Piper that he believes he found the demon Sargon in the Book of Shadows (which may be the demon Count Roget made a faustian deal with), Piper looks at it and says that they vanquished this demon five years ago. Which would've meant they vanquished the demon with Prue. When in fact the only demon that happened with was Zahn in season 6 episode 6, "Soul Survivor," and they did that with Paige.
Plot hole: When the Avatars agree to rewind time they say that they can either put the world right or save Brody but not both. This doesn't make sense since they're rewinding to right when they put everyone to sleep, which is before Brody was killed.
Other mistake: When Phoebe gets the premonition to see all the loss, she sees the scene where Piper dies in All Hell Breaks Loose. Since time was rewound this event never happened in this timeline, and we're never given any reason to believe Phoebe would know this happened after the time reversal.
Show Ghouls - S7-E15
Continuity mistake: When Phoebe is on the phone with Elise about the Cosmo interview, she jumps between shots from leaning over the kitchen table to sitting straight up. (00:05:45)
Continuity mistake: When Leo hugs Wyatt near the end of the episode, the way the pair hold onto each other changes. (00:38:15)
Continuity mistake: When Paige is at the bar with her newest charge we see the same extra walk by 3 times, going the same direction each time.
Something Wicca This Way Goes - S7-E22
Continuity mistake: When Zankou is looking at the spell in the Book to steal TCO powers we see that it is the same spell Aunt Gail used in "How to Make a Quilt out of Americans", except that in that episode she ripped the page out of the book. It shouldn't be there for Zankou to use. (00:09:56)
Charrrmed! - S7-E4
Continuity mistake: Baby Chris doesn't have a binkie in his mouth, then does, then doesn't. (00:39:23)
Something Wicca This Way Goes - S7-E22
Visible crew/equipment: When Agent Keyes enters the manor and walks into the kitchen, just as the hazmat team tells Keyes it's OK to breathe the air, the red tape mark is visible on the floor in front of Keyes' feet. (00:37:00)
Continuity mistake: After Leo rescues the driver in Texas, when it cuts to the manor Phoebe is wearing a pair of white gloves which she takes off and puts in her pocket, but when Phoebe insists she will not save another innocent until she finds out what happened to Leo, Phoebe is wearing both gloves again. (00:07:45)
Carpe Demon - S7-E14
Revealing mistake: After Leo's meeting on the bridge with two of the Elders, it cuts to Phoebe walking down the stairs as she catches Drake dancing, and when he approaches Phoebe to take her hands, the top of the set with lighting can be seen in the dining room.
Deliberate mistake: When Zankou and the Charmed Ones force the Avatars to "put the world back" by rewinding time, in the first shot of people waking up note the Jeep in the backround. The problem is the words "Jeep Liberty" are on the spare tire cover in this shot, but in the previous episode "Extreme Makeover World Edition" that spare tire cover is all black because those words were edited out in two shots. The first shot is when that group of people fall asleep, and second shot is when they all wake up the first time. (00:35:15)
Extreme Makeover: World Edition - S7-E12
Deliberate mistake: While Beta, Leo, and the sisters are walking through the sleeping city Paige notices someone in a "bad suit" moving, and as she walks over we can see a bit of the white writing on the SUV's spare tire cover, at the left side of the screen, but when Paige declares she's not paranoid that white writing has been edited out in this shot. (00:26:00)
Visible crew/equipment: While Leo and Piper are at the photography studio with their kids the Avatars appear, and in the shots facing the Avatars the red tape mark is visible on the floor, in front of Avatar Alpha. (00:01:10)
Someone to Witch Over Me - S7-E7
Visible crew/equipment: After Paige's guardian angel is snatched by Sarpedon, when Phoebe rushes out of the kitchen to find Paige lying on the floor, two long white tape marks are visible on the floor to Paige's left and right. (00:16:15)
Someone to Witch Over Me - S7-E7
Visible crew/equipment: When Kyle orders the helicopter to keep recording the survivor from the fire, Paige tells Phoebe that Kyle is really cool, then as Phoebe and Paige follow Kyle they pass the Celerity demon, and we can see the red T-mark at the demon's feet. (00:02:05)
Visible crew/equipment: After Leslie decides not to ring the manor's doorbell he turns around, and when he sees Phoebe as she walks up the steps, the reflection of crew members is visible on the car window behind Phoebe. Then as Phoebe and Les are talking, we also see the reflection of the boom mic on the window of the car in the driveway. (00:40:15)
