Bob Singer: “We know that the bunker’s in Lebanon, KS. They go out for beer runs, but we never see where they’re buying they’re buying the beer or the eggs or whatever, so for the first time we’re going to see Lebanon, KS, and see people who live in the town and how they react to the guys.”

We will see where the Winchester brothers buy their groceries.

Jared Padalecki: “Where do they get their money? Where do they buy their booze? How do they get their pizza? What does their Chinese joint look like? What does their liquor store look like? We get to see a bit of their world which I think flushes it out and makes the story more rich. We also get to see what the locals think of these guys. We get to see what normal people in a small town think of the crazy, weird dudes who are always wearing flannel and driving an Impala.”

Bob Singer: “They’re also a guest star I think the audience is gonna be–someone you know–that’s as far as I’ll go.”
