Thigh
John
Sherlock had especially thin thighs considering he would spend days just lounging on the sofa like some lanky, overgrown cat. John supposed running around London like a cheetah on speed would do that to you.

Sherlock
The only weakness of John Watson.
It wasn't the messy scar on his shoulder where a bullet had nearly taken his life.
It wasn't his heart; that was his strength, even if Sherlock hated to admit it.
It wasn't even his brain which was nowhere near as sharp as his own but still somewhat above average as much as Sherlock told him otherwise.
It was his bloody flawless thigh and the horrors war had burned onto the back of his eyelids.
