I had a conversation last week with princesscocoa (spookycocoa for now), and that prompted this fic. Looking forward to her version of this story. Angst and hurt/comfort:

Hidden Hurts – Sometime after Sherlock’s return, John discovers one more secret.

The gun blast still echoed as John dropped to Sherlock’s side. “I’m here,“ he said calmly, already mentally calculating the damage even as red bloomed on Sherlock’s shirt. He reached for Sherlock’s buttons and found his hands batted away. “Don’t be ridiculous,” grumbled John, grabbing his wrists in one hand and yanking the shirt open with the other.

John’s eyes went wide as he saw the many scars twisting across his friend’s chest. He knew about the nightmares, the things Sherlock would not say. But not this. Sherlock turned his head and closed his eyes, but whether it was from pain, shame, or something else, John couldn’t say.
