Lay Your Weary Head to Rest. Summary: In the final battle of Armageddon, Dean is severely injured. As he suffers through pain and multiple surgeries and the possibility of permanent disability, Castiel is granted a reward by Heaven that Dean struggles with understanding, Sam makes a decision that throws Dean for a loop, and a ten year old boy finds out his father is the man he always wished it was, but nothing like he expected. Somehow these four take something very broken and dysfunctional and make it into a family.
