Castiel will enter Supernatural's 12th season with renewed vigor...and a bit of an attitude.

Lucifer is no longer sharing the angel's meat suit, and, for the first time in a long time, Cas (Misha Collins) is at full power. He might not have his wings, but that doesn't mean Team Free Will's wingman will falter when it comes to using his mojo where it's needed most.

"This season so far, Cas has kind of gone back to more off his root personality," Collins told fans at Creation Entertainment's Salute to Supernatural in Dallas. "He's kind of a warrior/fighter/man on a mission, and it's been so long since he's been at full power and in that mentality that it feels refreshing and new."

What is his mission? As the season begins, Cas will pull out all the stops when it comes to rescuing Sam (Jared Padalecki). Once all three members of the Winchester clan are reunited, however, Collins' character will take on the monumental task of tracking down Lucifer. He was, after all, responsible for the Devil's jailbreak.

"[Cas will be] extremely motivated to get Sam back," showrunner Andrew Dabb explained to TV Guide Magazine. "He [does] things we know Cas is capable of but we haven't seen in recent years."

Unfortunately, a return to his former glory will turn the rebel angel into a cantankerous angel.

"He's a little bit of a jerk," Collins told Entertainment Weekly, noting that Castiel is now a tad "short-tempered."

Hmmm...sounds like the Cas of old, does it not? The Cas who threatened to throw Dean right back in the pit if he didn't show him a little more respect.
