Charmed

TRIVIA: Cole turns a year older in this episode.

When Paige is at the cemetary with Leo she observes that all the demons that she and her sisters vanquished were still running around alive and in the manor. However, one demon, Darla (a.k.a. Succubus), shouldn't have been. Darla was vanquished by Prue, Piper and Phoebe at least two years before Paige met her sisters.

In the alternate reality The Seer throws Cole a surprise 100th birthday party. However, in the season 3 episode Coyote Piper, Phoebe researches Cole's history the clerk tells her he was born in 1885 so that would have made him 118! However, it is likely that the "100th" was simply to be polite and treat Belthazor with respect, as the cake guy says "I thought you were actually 117" and then the Seer vanquishes him.

The window that Paige breaks when she fights Cole changes several times through the episode. When she breaks it, she only breaks the side below and the down side is well, but when Cole changes reality there is no window at all. Also when the sisters come to see if Cole is there, Paige closed the same window and now it has the down side again.

TRIVIA: The P3 broken image on the club that Paige sees is a reference to the broken power of three in the alternative reality. The same allusion was made in season 4 episode Size Matters.

Why is the Lazarus Demon free in that reality? It was previously stated that the demon was buried till the Seer freed him in the episode Marry Go Round. For that episode only she freed him to make her plan a success and she didn't need him in the alternative reality because she did not have the same plan.

TRIVIA: The Lazarus demon has appeared before in the season 4 episode Marry Go Round. In fact that was the first episode that showed that demon.

Assuming that Paige contracts her cold from being thown in the water, then would she really start sneezing two seconds after hitting the water? The symptoms of a cold take time to develop.

This episode is where Cole becomes an Avatar just like Leo who became one in Season 7.

In this episode the Belthazar potion is red though in previous episodes the potion is purple. In the season 4 episode Black As Cole the Belthazar stripping potion was red so he should've lost his powers in this episode instead of being vanquished because Phoebe threw the red potion at Cole.

TRIVIA: This is the first time that the sisters met Darryl's wife Sheila. Which is strange wouldn't they have meet her earlier like on special occasions like Phoebe's wedding or Andy's funeral?

In the beginning of this episode Phoebe is wearing the same outfit Paige wore when they switched bodies in the episode "Enter The Demon".

When Piper and Paige are mixing the Belthazar vanquishing potion, Paige picks something up with her right hand and mixes it up. However it is something that she never uses in the potion.

TRIVIA: When Leo orbs to Paige after she calls for him in the alternate reality and she asks for his help he says "all Hell is breaking loose up there" - this is ironic since that's also the name of the episode that Prue died in.

When Paige is blown out of Cole's window, she orbs but she doesn't go anywhere. If she was going to go flying somewhere wouldn't she orb to safety?

TRIVIA: Cole is finally vanquished for good in this episode - he creates an alternate reality where he was still Belthazar and Paige was supposed to be dead. However he wasn't invincible there and Phoebe vanquished him for good with the Belthazar vanquishing potion.

TRIVIA: This is one of nine episodes with the series title, Charmed, in it.

TRIVIA: This is the last appearance of Julian McMahon (Cole Turner) as a series regular.

During the kitchen scene where Phoebe first meets Paige in the alternate reality, Phoebe is only wearing one earring (on her left ear), but when the camera zooms out she is wearing two earrings.

TRIVIA: Michelle Branch performed her song Goodbye to You in this episode, and this is also a tribute to Julian McMahon, who left the cast after this episode.

When Paige told Phoebe to grab Piper's hand (so the three were touching), the lights came from the ceiling and Paige got her powers back. However, in the season 4 episode "Charmed Again (1)", Patty told Phoebe and Piper that the three of them needed to be around the book to be Charmed again and Leo said the lights just meant she was supposed to be there. Paige should not have gotten her powers back, unless the three were around the book.

TRIVIA: In this episode, Paige says that when the Elders realized they needed her to reconstitute the Charmed Ones they through out the witch/whitelighter rule allowing for Leo and Piper to keep their baby.

The Lazarus demon is kneeling down over a dead body when Piper freezes him, but when the shot goes back to him, he's standing.

When Cole comes home at the beginning of the episode, the picture of him and Phoebe is on the left side of the table and the box is on the right side. When Phoebe picks up the picture at the end of the episode, however, she puts it down on the right side of the table and the box is now on the left side.
