Wow, this was so brutal and sad. Wonderful job getting into both brothers' heads - their voices transported me back to the tail end of season four and all of the pain and angst that came with it. I especially like how you depicted Dean being uncomfortable with simply leaving Sam to his fate, good or bad - as he was, I think, in the episode - yet not uncomfortable enough to actually stop and find a way to cure Sam.

And Sam, oh, Sam. My stomach was roiling, reading about him drinking his own blood.

Because Sam’s on the floor and limp, eyes closed. Still breathing, and that’s good, but there’s blood on the floor and Sam’s…Sam’s mouth is fixed to his wrist and Dean can feel his gorge rise looking at the smears of blood on the skin and a few drops sliding away from his mouth even now, and the way his throat works once as Sam swallows.

His skin is sallow and pale and Dean can see without thinking that Sam is killing himself and that he probably doesn’t even realize.

Wonderful job!
