It's training time with the Shadows and Graves is watching over the training. He's checking their form, aim, etc.

He walks behind the soldiers which are all lying on their fronts and aiming at the targets. Then he spots you in particular. Lying in front of him on your stomach, like everyone else is, also aiming at the targets but those pants do nothing to hide that ass you have. He can't help it. You're very distracting...
