Every time I watch The Great Game, one thing bothers me:

There is no way a genius like Sherlock would treat a gun like that. I mean, he’s literally scratching his head with it. He may walk on the wild side, but he’s not an idiot.

I watched this again the other night to prepare myself for Reichenbach Falls, when suddenly it hit me.

Where on earth did Sherlock get a gun from, anyway? Not John, definitely.

And then it hit me:

OH.

MY.

GOD.

HE’S BLUFFING!!!!
