“I've got demon blood in me, Dean. This disease pumping through my veins and I can't ever rip it out or scrub it clean. I'm a whole new level of freak! And I'm just trying to take this—this curse...and make something good out of it. Because I have to.”
— Ben Edlund, Cathryn Humphris, Sam Winchester, Jared Padalecki, imdb.com
