Corrected entry: In the emergency room after Piper has been shot, it is clear to see that Piper's bullet wound is a through and through, meaning the bullet went in and out, BUT if it did, that means that it should have hit Prue after exiting Piper because Prue was right in front of Prue when the shot was fired.

Corrected entry: In the last scene when Prue and Piper are lying down to die, Leo should have come. Being their whitelighter, wasn't he supposed to be able to remember what happened even after time resets itself? If that was the case, he would have known they were going to be thrown against a wall and almost die.
Correction: Cole said that he wanted to be able to tell Prue and Piper that Shax was going to come back. He was never given the opportunity and as far as we know, Leo was still in the underworld with Phoebe, protecting her. And as far as Leo knew, Piper and Prue were going to be warned about Shax, so really, as far as everyone knew, no one had anything to worry about until Prue died.
Correction: This was explained by Grams that Prue was busy, in other words she is letting the living sisters move on with their life and Prue is getting use to being dead.
