“And was that the last we saw of original Meg? She left such an impression on me that I could swear that wasn’t the end of her. She did that great; the whole exorcism scene…”
YES! Mikki Aycox was fabulous in that scene! We see her once more, in “Are you there god? It’s me, Dean Winchester”. Only, she’s not a demon anymore. She’s just a pissed off, vengeful-spirit Meg Masters who is angry with the Winchesters for not being able to save her.
