User blog comment:Cuvince/The Return of Bobby?/@comment-4807493-20120526094226

It's a good question about Bobby coming back - one that Jim was asked by a fan at AHBL today. He doesn't know if he'll be back for S8 yet...

Still, the souls of monsters and other creatures that were banished by God tend to reside there. I think Cas and Dean being there is probably a first as far as human souls and angels go (even if he is fallen, he's still got his grace).
