User blog comment:Malthael Archangel of Death/Cosmic Entity vs God/@comment-70.93.90.147-20171106195545

I don't buy that God just "rebuilt him" either, it's obvious that prior S13 God could resurrect any angel on a whim with no restrictions other than needing more time when it comes to archangels. But now than has since been retconned with introduction of the Cosmic Entity, leaving uncertain whether the aforementioned made a deal with/allowed God to resurrect Cass all those times or if your theory is correct, Malthael Archangel of Death.
