CASTIEL ESCAPES PURGATORY – Sam (Jared Padalecki) and Dean (Jensen Ackles) are stunned when Castiel (Misha Collins) suddenly appears back on Earth with no memory of how he escaped from Purgatory. Meanwhile, Mrs. Tran (Lauren Tom) enlists a witch (Cyrina Fiallo) to concoct a demon bomb, but the witch double crosses Mrs. Tran and turns her and Kevin (Osric Chau) over to Crowley (Mark Sheppard).
