Sacrifice for the Lesson Not Learned
Dean's unconscious when Sam returns, his knuckles raw and bleeding from beating the guys who hurt Dean to a pulp. Sam thinks he should be happy to have avenged his badly wounded brother, but now he just feels empty inside. Hollow.
When he places his hand on Dean's pale face to check on his condition, Dean flinches away from Sam's touch, something he's never done before, even when unconscious.
Sam sits by his brother, mourning the loss of the once unshakable trust they once had in each other - an unexpected casualty.
But if that's what it'll take to kill Lilith…
A/N As much as I want the brother's to reconcile, I also wanted this to fit in with the shows canon so I'm ending my story here. Sadly, I fear that things will only get worse between Sam and Dean before they get better.
