Dean's struggle with mark of Cain becomes overbearing, and just when he feels he can't handle anything more, John Winchester appears in the middle of night, standing at the end of his bed. What's more, is that his being there is a complete mystery. Sam and Cas are concerned, and think maybe Dean has lost it some. When Dean suddenly becomes seriously ill, the two don't know what to think. Things only get worse for team free will from there. This will be a DESTIEL fanifction. BUNKER FIC CAUSE YEAH, THAT'S AWESOME Will also turn into a DEAN CANCER fic.
