When this season began I was terribly dissapointed in a lot of things Billie for example the series started looking more like 'BILLIE' instead of 'Charmed' but I have to say that after Vaya Con Leos the season got better with a few stupid stories excluded but I liked the ultimate power story, finally Billie got some real purpose although I still don't like her being that powerfull but anyway.
In this episode we finally get some action, I totally love Piper in this episode she keeps getting better and she wants to kill Christy and Billie, how cool is that? :P.
This episode was just what Charmed is supposed to be and I really hope that the 3 last episodes are the same way. I read somewhere that this was Litvacks last episode so I just want to say good work and I'm looking forward to the next episode.
