He was!
Watched
Brain Drain last night, awesome episode. The Source tapping into Piper's mind, making her think she only thinks she's a witch, that she's actually in a mental institution and that Phoebe and Paige are only her inmates not her sisters very much reminded me of Smallville's S6 episode
Labyrinth. I loved how through all that, it made her realise that she couldn't just give up being a witch, having powers was a blessing and that she can still have the normal life she wants along with it.
