This is the episode I have been waiting for in Tv-Series history! Finally we see someone deal with the loss the real way. The painful way. Grief can't be dealt with within 45 min and this show made sure that the halliwell sisters stayed as real as fiction allows.
Piper turning into a fury because she suppressed her anger reminded me of myself. Of course I stayed human ;) and paige helping piper through that phase by sharing her pain was just awesome! and touching too.
Plus the Furies are one class of demons that obviously took some time creating them. Unlike the Grimlocks for instance. The Tattoos are wild and the way they disappear makes me wonder how many ways the writers will find to make someone "shimmer", blink or orb :) But vanishing in smoke is kinda classy you have to admit that.
And the last scene is my absolute favorite of this episode: when Piper says "her sister" upon being asked who she was Paige/Rose looks down and smiles. Humble, proud, cute. Love it!
