Jensen Ackles expressed gratitude for the 15-year run of "Supernatural" and thanked fans for keeping the show alive. He spoke about how his castmates became like family over the years and how much he enjoyed working on the show. The series ended at the discretion of the cast, and Ackles is now working on a prequel series called "The Winchesters." Initially causing some upset with fellow actor Jared Padalecki, the two resolved their issues and reaffirmed their brotherly bond.
