It's been six months that Dean gone missing. No one can tell if his dead or not. Neither angels nor demons knew where he is. They can't feel his presence.

It's been six months from that exhausting hunting day as they just finished raiding a vampire lair. Dean and Sam are preparing to go to sleep when Dean receives a phone call. That phone call makes him dash to impala, Sam followed him.

That day, Dean cries like he never did before, crying his agony and guilt out of Sam. That day he decided to stop hunting. That day he decided to just focus to his two little angels. That day he promises that he will never live them again.

Sam is a very careful person, not that his not careful before. He wants to keep his promise to his brother. He doesn't want to ruin it, he loves his brother and keeping his whereabouts is the only thing he can do for what sacrifices his brother did for him.

He still hunts with Bobby and Castiel. Every night, Bobby drinks and tells story about Sam and Dean's idiocy as he call it and how he misses Dean. Sam watches how their father figure cry his sorrows about Dean gone missing.

Sam can see the building depression on Castiel's eyes through the months they're together. The depression that makes Castiel stares on the horizon trying to hear Dean's prayer. He also wakes up in Castiel's footstep as he think and tries to reconnect with Dean. But what makes Sam almost tell his secret is when Castiel become almost like a walking dead. Doing what he does not even questioning it and almost die in a hand of a witch. He also makes a deal again with Crowley as he become more desperate to see the righteous man but it comes out as a failure for no one can track his presence, only Sam knows.

Sam felt guilty for many times but his promise to his brother is his priority. Sam holds the pretention perfectly but the guilt is painstakingly crawling in his heart. But before he can blurt out where Dean is, heaven and hell start a new war.
