Hopefully she doesn't mind the loud curse in her ear as the bullet fires, and although it doesn't hit him it's bloody lucky neither of them are hit. In an alley like this, with a concrete floor and two tall buildings on either side that it doesn't ricochet off a wall and hit either of them.

"What the bloody hell was that? Trying to kill both of us?"

His surprise at such a bloody stupid act means that she can slip out of his grasp, and yeah, he'll kick himself over that for days to come.
