'Supernatural' preview: Misha Collins returns as Castiel... with Meg!Add to Favorites | Supernatural
Collins will come back in "The Born-Again Identity," the March 23 episode, and he'll appear in two more episodes this season. When Sam has to be institutionalized after completely losing grasp on reality, Dean scours Bobby's old contacts for help, which leads him to Castiel. As the title implies, Castiel has no memory of actually being Castiel.
Dean's old friend is living as a healer (with a few other intriguing powers) but has no idea that he's an angel, or who Dean is. Given the fact that Castiel is the one who knocked down the wall in Sam's head in the first place, he's likely the only person who can reconstruct it, so Dean is beyond relieved to see him, as Jensen Ackles told us when we visited the set last month. (There's also the part where, without Sam, Dean is completely alone in the world, so we're guessing he's not exactly averse to a friendly face.)
As you can see from these new photos, Castiel isn't the only blast from the past who shows up in the episode. Meg (Rachel Miner), the only demon who has crossed the Winchesters and lived to tell the tale, makes her Season 7 debut. That's generally never a good sign.
"Supernatural" returns with new episodes this Friday, March 16 at 9 p.m. EST on The CW.
