Last week's episode of Supernatural may have been titled "Out with the Old," but it's this Friday when a couple of old friends will pay Sam and Dean a visit.

First, much to the chagrin of Sam, Mark Pellegrino will reprise the role of Lucifer, taking this hunter to such a breaking point that he ends up in a mental hospital.

From there, Dean will seek out all the assistance he can find, eventually being led to a healer played by... Misha Collins! But this returning star won't be taking on the classic character of Castiel, not exactly at least. Watch the official preview and then a sneak peek from "The Born-Again Identity" now.
