“Supernatural”: The hug between the Winchesters in last week’s episode marked a turning point for them — and a return to the sort of solid bond they haven’t had in a few seasons. “Given how the boys reunited at the beginning of this season, not on the best terms, the one thing that did unite them was this sense of revenge against Crowley and the demons,” says executive producer Jeremy Carver. “Now, we’re going to see things start moving pretty quickly and pretty wildly. A lot of balls in the air. The boys are really going to be constantly confronted with the idea of, ‘Okay, we want revenge, but how far are we willing to go? How much are we willing to sacrifice?'” It’s a theme that drove them when “Supernatural” began, and we’ll find them looking at the question in a new light toward the finale.
