John looked into Sherlock's eyes and he felt hope fill his chest. Maybe then, he wouldn't die in vain. He only hoped that Sherlock would not forget of this promise once he was... well... gone.
"Thank you..." he whispered.
His cheeks burned red when Sherlock fiddled with his jumper, he was not used to having him so close and he felt suddenly self-conscious.
"I- well, fine," he muttered and took the garment off, his shirt under was spotted with red all over his back.
He took that off as well and it turned out his back was black and blue with bruises and covered with knife wounds. Deep enough to bleed, but not enough to cut the muscle.
