You were a great sniper, you had left the military to work by yourself, earning money from headshotting people.

You knew you were a great bounty, but you had killed lots of bountyhunters. None had been close to getting their bullet into your skull.

You were sitting by yourself, as you suddenly get eyecontact with a sniperscope. Looking right through the scope, staring through the soul of Ghost Riley.

You pull out your rifle, he knew this was YOUR hunt, and he was the prey.
