Scenes were filmed on location with the Impala parked outside “Lil Skipper’s Beachside Grill” with Sam, Dean, Cas and Jack
There are scenes in the hallways of heaven and the Bunker.

OUT OF THE DARKNESS – When Sam (Jared Padalecki) and Dean (Jensen Ackles) join forces with an unexpected ally, the outcome will alter the course of two lives. Meanwhile, Heaven faces an attack from a dark force, driving Castiel to make an enormous sacrifice to make things right. The episode was directed by Eduardo Sanchez and written by Meredith Glynn (#1408). Original Airdate 12/6/2018.

Going Back to Heaven. “Heaven is basically defenseless,” executive producer Brad Buckner explained. “There’s a few remaining angels. So Heaven basically is under assault. Under assault by whom remains to be found out. But Cas has to go there and do his level best because Heaven’s in trouble and could potentially be shut down.” As for the rocky relationship between Cas and the other angels, Misha Collins also hinted that “I think that at this point Cas and Heaven are mending fences, but the fence is still badly broken because Heaven is in such bad shape. We are sort of forging an alliance, but at the same time Heaven is badly broken and is becoming more broken.”

Supermonsters. Meanwhile, we’ve gotten some hints that Michael seems to have been creating a collection of supermonsters to help aid him with his plans. When we asked Buckner how that story would continue to develop, he said “It’s going to continue to develop because he needs an army. He can’t do this all by himself. So in apocalypse world it was the angels — there are [not enough] angels, [and] he doesn’t trust them much anyway. So he is recruiting these supermonsters and they’re going to rear their head before long. I think by the time we hit the mid-season finale [airing on December 13] we’re going to find out exactly what’s going with that.”
