Nicely done. I like the idea that not only did John give his life for Dean, but that in death, he’s still looking out for him.

Favorite lines:

Then the axe landed where Dean wasn't, an inch left of his head, and Dean was up on his feet and firing rock salt at the apparition. It vanished, screaming in frustrated rage.

"Whoo! We showed that son of a bitch!" Dean shouted, high on adrenaline and life.

Sam couldn't move. His brother should be dead.

Love this. Of course Dean’s all gung-ho, acting completely oblivious to what almost was, and of course Sam is frozen, all too aware of what should have been.

Sam pushed Dean onto the mattress, then pulled off his boots and set the wastebasket by the head of the bed before Dean even passed out.

Aww, Sammy’s such a good little brother. *pets him*

Dean muttered something in his drunken sleep. Sam shushed his brother, pushing Dean's too-short hair back from his forehead.

This is such a sweet image. *pets Sam again*

Try as he might, Sam couldn't get angry at the thought that Dad was looking out for Dean.

In fact, all Sam could think was, It's about fucking time.

Awesome ending. Just love how you wrote it, those last two lines especially.
