We have more Supernatural casting news for season six.

It's already been confirmed that Misha Collins and Jim Beaver will appear again on the show, while Mitch Pileggi is also slated to recur.

Now, Zap2It reports that Fred Lehne will reprise his role as Azazel this fall. This demon was killed by Dean to conclude season two, so it's unclear how he'll make an appearance in the fall. The best guess: a flashback or a time-traveling sequence.

Over the years, Jeffrey Dean Morgan, Rob Labelle, Lindsey McKeon and Pileggi have all portrayed Azazel.

No word yet on whether Pileggi will portray this character or Sam and Dean's grandfather when he returns next season. It seems clear now it will be the latter.
