P3 H20-The sisters must face and destroy the demon that was responsible for their mother's death 20 years ago. In the process, they uncover a chapter of their mother's life that they never knew about - one that disturbingly mirrors Piper's current relationship with Leo. Superbly written and wonderful heartwarming story, "P3 H2O" (Cool title) sees the sisters coming to turns with the lost of their mother when they face the demon that killed her 20 years ago. All 3 leads give great performances, but Shannen Doherty comes out on top this time. She is brilliant as Prue must face of fears over her mother's terrible fate and get over the pain that has always been within her. It makes perfect sense that Prue would be the saddest of her sisters as she remembers every small detail of her mother's death. You can honestly see how angry and hurt Prue is, not just still dealing with the reality of losing her mother but going up against the demon that killed her must be a frighting experience. I especially love the scene where Prue accepts her fate:
Prue: Sam, would mom's plan have worked if she had finished it?
Piper: But you said her power, my power, doesn't work against this demon.
Phoebe: So that's it, we use mom's plan with one difference, the witch at the end of the dock is not gonna be the one with the power to freeze..
Prue: It's gonna be me.
Scott Jaeck (Sam Wilder) makes for a great guest star and gives a stunning performance as the fallen whitelighter. You truly feel sorry for the character as he was forced to live with the guilt of Patti's death for all those years hiding at that camp. I also love the development of Patti and Sam having an affair which is truly ironic seeing as how Piper and Leo are in the same situation. The parrales that both couples share are amazingly similar and Piper and Leo's reaction to the affiar is well acted by both Holly and Brian. The scene where Piper freezes Leo from getting hurt just like Patty did to Sam 20 years before was probably the best scene to show this. This revelation gives hope for Piper and Leo's relationship but at the same, makes it's difficult for Leo as his feelings for Piper are going stronger each day. Leo's little speech to Piper about that was so touching as well as heartbreaking making their relationship hopeless.
The water demon brought some really above average effects for the series as well as some disturbing scenes. I love that the water demon used his past victims to lure new victims he can drown. The episode also benefits from the great camp setting which is a freshing change from the city of San Fransico. Other great scenes is Phoebe's intense premontion of her mother's death which Alyssa pulls off the overwhelming experience with such passion in her performance. Then there's Sam's tragic death and the sight of his spirit walking away with Patti's is such a beautiful moment. All and All, "P3 H20" sees the writers and actors creating a remarkable episode that will be remembered for its superb writting, a wonderful storyine and touching performances from various cast members as well as guest stars.
