John's sly grin didn't move from his face, he lifted a blank DVD case.
"Oh really, I guess I'll just drop this off to Lestrade…"
Sherlock's eyes narrowed.
"You wouldn't"
"I invaded Afghanistan, of course I would."
Sherlock picked up a corn and put it slowly in his mouth.
"I will get it back."
"And deprive the world of a 6-year-old Sherlock singing 'Away in a Manger? Never."
