It’s double the trouble on the fall finale of The CW’s Supernatural (Wednesday, 9/8c), as both a fan favorite/former foe and the Winchesters’ current Big Bad return, as seen in these fresh photos.

Convinced that God wants him to make a trip to Hell, Sam turns to Crowley for help. And whatever potentially disastrous plan they come up with, it must work, because Mark Pellegrino is back in his cage as Lucifer.

Elsewhere, a grown-up Amara unleashes her power on a poor, unsuspecting town, while Dean tries to understand her hold on him.

Series star Jared Padalecki says he didn’t expect the Winchesters to go where they go in next week’s big installment “until at least the season finale, but we get right to it. And the brothers are very committed to fighting alongside each other, to getting rid of The Darkness and trying to figure out what it’s going to take and how to do it, going through all alleys and channels.”

“Episodes 9 (the fall finale) and 10 are my favorite episodes of Supernatural in a long, long time,” Padalecki continues. “I love the twists and turns — none of which I can probably say without getting out of here alive.”
