Supernatural - A New Angel?

Here are a few tid-bits of news RE season 6 of Supernatural

Got any Supernatural spoilers? — Samantha
ADAM: The show is adding a new angel who's gone a bit rogue. The possibly recurring character is described as an attractive charmer who appears slightly manic on the surface but carries a great sadness.

Could be interesting, does this mean that Cas may get laid? would be fun to see after the strip club scence in season 5!
