Here's the full description of episode 8.07 "A Little Slice of Kevin" with a bit more detail about Castiel's return.

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 (guest star Lauren Tom) enlists a witch (guest star Cyrina Fiallo) to concoct a demon bomb, but the witch double crosses Mrs. Tran and turns her and Kevin (guest star Osric Chau) over to Crowley (guest star Mark Sheppard). Charlie Carner directed the episode written by Eugenie Ross-Leming & Brad Buckner (#807).

I think it is meaningful that everyone's a guest star apart from Misha. So Crowley and the Tran's will leave soon, and the witch won't be in long, too.
