John's revelations had shaken him, brought him to the realisation of his own likely fate had this short, blind, brave man not risked himself to break him out.

"Why?"

"Why did they take me? They seemed to think I had some information that was useful to them." John shrugged, pushing his plate to one side and resting his forearms on the kitchen table.

"And did you?" Sherlock watched the other man's face closely, looking for any signs of deception.

John grinned, conspiratorially.

"Well of course I did, but once they'd beaten me senseless, and damaged my optical nerves, they convinced themselves that if I had known anything I would have told them long before things got that bad." A cold, hard look settled on his pleasant features. "But if Barrymore thought I'd risk my former comrades by giving him the locations of the Poppy fields, and Taliban drug lords..."

"Taliban drug lords? You were in Afghanistan?"

"Army doctor, attached to 5th Northumberland Fusiliers." Standing quite suddenly John turned away, slamming his plate into the sink. "He was mad if he thought I'd betray my friends in Kandahar and Camp Bastion."
