I don't read that much SPN, because I'm not a fan of the Wincest, but this is the sort of story I want to read. I love the outsider view and Kathleen is the perfect lens, since she isn't already persuaded that the supernatural exists. She can only judge on the evidence, but she's smart and honest enough to judge on all the evidence, not disgarding what doesn't fit a preconceived idea. Lovely, lovely story.
