Let's face it. John's initial draw to Sherlock was his impressive deductive skills but the second, and most important, was the ability to include him in on danger. John craves the rush of adrenaline. A new battlefield. Yes, he's grown a bit soft over the time he's spent watching chat shows or staring at Sherlock's grave. Three years of monotony is a long time for a man his age to jump right on back to the danger one Sherlock Holmes might offer.

Except, Sherlock doesn't include him any more. It's difficult for John to understand why they've grown apart. Surely, eighteen months joined at the hip -- when he'd not been accidentally or otherwise left behind -- is more than enough to overcome double that time apart?

"Where were you?" Once upon a time, John'd never thought to ask such a thing. He doesn't expect a response now either though. He smells like a pub. His eyes are still unfocused.
