Supernatural boss reveals the originally planned series finale ending

Entertainment Weekly

"Now, we know precisely what was supposed to go down in the first draft of that finale," says Samantha Highfill. "Production designer Jerry Wanek put together a book for the cast and crew that is now available to buy, complete with pages and pages of the various sets they built for the long-running series. For that book, (co-showrunner Andrew) Dabb wrote about one of the final sets constructed, which they ultimately didn't get to use: the inside of Harvelle's."
