I don't remember a whole lot of the story but it has Dean living with Lisa and Ben. They go to a bookstore and Dean finds the Supernatural books. He reads them and thinks all the crap that happened in season 6 is real but it turns out that Chuck is missing and the publisher hired ghost writers to continue the story. Then Becky takes over writing the books and Dean finds Cas (and I'm pretty sure Sam, too.) I'm almost certain that it was Destiel. That's all I remember so I'd really appreciate a link. Thanks!
