May 2017 marks the end of the twelfth season of the CW hit Supernatural, a television show about two demon-hunting brothers (and an angel) that is at the center of a fan community as tight-knit as family—a virtual support system that spans the globe. The three-time People’s Choice Award winner for Favorite Sci-Fi/Fantasy TV Show and Tumblr’s 2015 Most Reblogged “Live Action TV” show has made a name for itself by supporting and encouraging its fans to “always keep fighting,” a main theme echoed in the show, and demonstrating the inspiring truth to a memorable line from early in the show’s run: “Family don’t end with blood.”
