Fandom: Supernatural
Pairing: Sam/Dean

Summary: He lifts his hand and twists it harshly, fingers curled like a claw, and Sam feels his inside twist, churning, organs grinding against each other, his ribs digging into his heart and lungs and the pain is so intense he can't scream, can't do more than choke on the blood that rises in his throat.
Pick up the book, he thinks at Lucifer.
"I can't," his hallucination says, something like panic in his voice. "I can't, I can't. We're trapped. I can't."
Review: This is a fic which hurts, not gonna lie to you. But it's also completely brilliant. I have a real soft spot for stories dealing with hell-traumatised Sam, and this is one of the very best.
Be prepared for angst. So much angst.
