Phoebe: Things are not as black and white as they used to be, okay? I can't just go around killing demons anymore.
Paige: Why not? We heard you just killed two last night.
Phoebe: Yeah, well, that was different. They were getting on my nerves. I promised Cole I wouldn't kill any more. And killing Malec would have been a huge betrayal.
Piper: Malec? You're on a first name basis with the demons now?
