I know Lucifer can be such a baddie, but I loved writing his dreams with Sam. He's so dynamic and amazing to write -- no idea is too gruesome or insane when it comes to the Devil, and with dreams you add in the free rein of settings to choose from. And the dreams helped to reiterate that Sam's not just on some vacation from hunting -- evil's still gunning for him and even in the dreary little town he's never quite sure that he's safe.
