Black As Cole-Cole must face his true demonic nature when he is faced with another demon who is mistaken as the murderer of local witches who belong to the same coven. Meanwhile, Cole proposes to Phoebe, and Piper and Leo consider their future involving children.
A superb episode that sees the writers continuing to develop Cole when he becomes the main suspect in a string of murders involving witches. Of course the whole "being framed by a copy cat killer" has been done so many times, but it's used very well here, especially in developing Cole. Julian McMahon is wonderful throughout as Cole must face his dark side head on and comes to terms with the monster he was in his past. The bedroom scene between Cole and Phoebe is a beautiful as Cole confesses to Phoebe exactly what he was and still is. Alyssa Milano is also wonderful when playing Phoebe as Cole's guide and support system. No matter what Cole has done in the past, Phoebe always finds some way to find the good in him and it's nice seeing Phoebe so determined in this hour.
All the guest stars are great including Heather Dawn as Emma, the vengeful widow after the demon who killed her husband. She makes Emma's storyline very real and convincing, especially when talking to Phoebe about losing a loved one to evil. Aaron Brumfield is also good as Sykes and I loved his M.O. about beeing Belthazar's prodigy. Also, the make-up team did a stunning job of making Sykes look like reversed colored Belthazar with his skin being all black and red lining on his face. The climax is very suspenseful when Emma throws a potion at Cole and you think his vanquished, only for Cole to still be alive afterwards. It's a shocking development with Cole turing human and it makes for some interesting issues ahead for Cole and Phoebe. Also, the sub-plot with Paige giving Piper and Leo a fake baby so they can pretend to be parents was hilarious, especially when the baby gets fryed during a demon attack. All and All, "Black As Cole" is a superb character study of Cole by developing the character in significant ways.
