While, I can't post this with the journal till IJ continues emails...

loveinhell I would literally kill for a Rachel Miner as Meg Masters. It would be for a cross-verse line.
It would take place when he wakes up from what he believes is hell in a hospital room. His soul escapes hell and back into his body. Only as a demon in his old body. His beloved's body (Betty from the movie Hide) is standing next to the bed. In all her glory, long dark hair instead of blond, and full of leather. The look was different, but it was still her through and through. Or so he believed. The demon version of his beloved is Meg, in Betty's body. Her soul died and dissipated. They didn't know where to or care. Meg acquired the body much like Ruby had. She has all of Betty's memories of their wild adventures and has fallen for Billy. And we can make it up from there.
