Continuity: Near the end of the episode, in the scene at P3, Phoebe launched a jump kick at a warlock after Paige has been knocked down by a small energy ball. Everybody else in the club was frozen by Piper, but when Phoebe lands she jostles a blonde extra who moves from her pose. Submitted by DavidK93

Other: The one demon that knew about the 40s party was vanquished, and he went straight from spying on Paige and Phoebe at P3 to "glamouring" into Leo at the Manor. He had no way of telling Devlin about the 40s party, and yet it was still full of demons waiting to kill the Charmed Ones, with Devlin "glamoured" into Melody as a trap. And Devlin didn't even have that power - the demon that was vanquished did.

Plot hole: Why did Phoebe have to write a spell to vanquish the warlock in this episode? When they have vanquished warlocks before they used the power of three spell, "the power of three will set us free". (Time)

Continuity: After Phoebe jump kicks a warlock and falls to the ground, there is a blonde woman standing next to them. In the next shot of the warlock, when Piper blows him up, the woman is gone. But all of the mortals had been frozen, so she couldn't have moved. (Time) Submitted by DavidK93

Continuity: If Leo can't hear the girls call him when HE is underground, he shouldn't be able to hear the girl's call him when THEY are underground and he doesn't know they are at P3 until a few minutes later.

Factual error: On the wall of Paige's bedroom when she was a teenager is a Metallica poster for "Garage Inc.", a CD not released until 1998 although Piper later says that Paige has gone back to 1994. (Time)

Plot hole: When we see Paige's 1994 bedroom, she has what appears to be a Bride of Chucky doll. The movie "Bride of Chucky" wasn't released until 1998. (Time)

Other: After Piper freezes the first crime scene that Cole and Phoebe (aka Frankie and Lulu) have hit, Piper unfreezes Darryl by touching him but at the beginning of the the episode when Piper and Cole are touching the car that Piper froze, to stop it from exploding after a car crash, while trying to help the woman inside, the car never unfreezes. This is somewhat inconsistent through the entire show a lot of times they can unfreeze things by touching them and then a lot of times they can only unfreeze things by Piper using her pointer finger to either unfreeze a head or a foot or some other body part. (Time)

Other: Paige and Leo are in Paige's 1994 room for at least 1 minute and don't smell the cigarette smoke but when Paige's father enters the room, Paige hugs him and in the middle of the hug he immediately smells the cigarette smoke. (Time)

Plot hole: Piper convinced Paige that they should use their powers to make Andrew confess to murder. Paige wonders why it's okay to reveal their powers to a mortal, and Piper and Leo explain to her that it's all right to use their powers on a mortal because they're trying to help an innocent. But in episode 2-19: "Ex Libris," Prue wanted to use a truth spell to force the pawnshop owner to confess to murder, and Phoebe pointed out that it is an abuse of their powers to "punish the innocent." Submitted by DavidK93

Continuity: In the teaser, Phoebe has a vision of a murder. When she first sees the shadow of the attack, the assailant is holding his victim down with his right hand while stabbing with his left. Then when the vision focuses on the Medusa head tattoo on his forearm, it is the right arm that is stabbing. (Time) Submitted by DavidK93

Revealing: During the episode, Paige is wearing a sleeveless top, but when she thrown across the attic by 'The Source' the stunt double is wearing sleeves.

Other: In this episode, the Source talks about the "Ultimate Power" being the Hollow. But in Season 8, we learn that the "Ultimate Power" is Billy and Christy. (And they end up taking in the Hollow, so now are they the "Ultime Power" times 2?) Which is it? It can't be both.

Revealing: At the end of the episode after Phoebe and the Seer put the hollow away in its place, she leaves, but when it next cuts to a closeup of Cole, in the corner of the screen you can see her hair.

Revealing: After Page turns Pheobe invisible, Pheobe jumbs up and down, but the clothes in the mirror that are supposed to be her reflection don't move at all.

Continuity: When Paige was invisible and Cole watched the blood, there was a large pool of her blood, but in the next shot, the pool of blood was smaller.

Factual error: The Seer tells Cole about the importance of the upcoming "Harvest Moon." But this episode aired in mid-March, while the Harvest Moon is the full moon closest to the autumnal equinox. The full moon closest to the vernal equinox is known as the Worm Moon. Submitted by DavidK93

Plot hole: When Piper freezes an object it always continues with its path when it unfreezes, but when she unfreezes the knife Rick has thrown at her it drops to the floor.

Continuity: In this episode, an invitation to Piper is addressed to 1329 Prescott Street. But in episode 1-7: "The Fourth Sister," the Halliwell sisters put up a flyer for their lost cat, and it gives their address as 7571 Prescott Street. Submitted by DavidK93

Continuity: The name plate under the photo of Leo at the Veterans Association indicates that he died on November 24, 1942. Paige's research indicates that Nathan and Rick both died on the same day as Leo, but she later finds out that they were buried at the V.A. on November 22, 1942, two days before they are supposed to have died.
