Chapter Summary: Castiel knew that Metatron killed Dean, but he expected his friend would make it to Heaven. When that doesn't happen he reluctantly joins forces with Sam to try to figure out what happened and how to fix it. He surprises himself by the pleasure he takes in working with Sam and soon comes to the realization that he loves Sam for his own sake. Convincing Sam of that, or that such a thing is even possible, may prove even more of a challenge than hunting down a super-demon and curing him.
Warnings: Violence, suicidal ideation, depression. Some sexual content. Please note that Dean is either a demon or recovering from having his twisted demonic spirit straightened back into a human soul and as such presents as neither cuddly nor sweet.
