How long will it be? How long till you lose your patience with me and let me fall apart? I keep waiting for it all to drop. For you to walk away and never look back but although I expect you to, still you are here. You made it clear we weren't brothers any more and strictly to be work partners so why do you still care? What happens when it all goes to Hell and you give up on me. Realize I'm a lost cause not worth saving. Again. What happens after Abaddon's dead, Heaven is restored and Crowley is no more? Will you still care then?

Dean had so many questions and no answers. He couldn't foresee the future and he wasn't even sure he wanted to. He sat silent, slumped over yet another book in their futile attempts at finding the last knight of Hell. Sam sat across from him. No eye contact and no unrelated speech other than their seemingly never ending mission. He took deep breathes, determined to hide his pain. Physical and emotional. The Mark burned his skin and turned his blood cold. His mind filled with useless and painful conversations with his brother. Sam wouldn't do the same for him, his brother would not save his life.
