[The quick succession of gunshots conceals lesser sounds to the point where only Sebastian hears the disgusting sound of the bullets burrowing into his flesh, the wet splat right as the blood starts spurting over his uniform, onto the ground. He staggers back with the force of the shots: one, two steps in quick order. For a moment he tips backwards, as if he's going to collapse - to really fall over, dead.
But then he rights himself. His head rolls forward and he coughs (an ugly, wet sound; something must have torn inside him) twice into his hand. This deep into the forest the trees block the sunlight to the point where it might be difficult to see what's in the hand even as Sebastian opens it, holds it out for Ciel to see its content. The way his palm is coated in blood can't make it easier to make anything out. However, the muffled thud, thud of two small but heavy objects hitting the dead leaves as, moments later, he slowly lets them fall to the ground should remove all doubts.
Sebastian says nothing, doesn't advance right away, but now his eyes glow red.]
