At the climax of The Dark Knight Rises:
Talia is in a truck that carries the bomb, Batman is in the Bat, Selina Kyle is driving the Batpod, and there's a couple of tumbler-tanks around there. Batman is trying to lead the truck to where Lucius Fox is, to put the bomb back in place and disengage it. Thalia stubbornly refuses to let them do so.
There's a lot of gunfire coming from the bat. Talia tells the truck driver, next to her, to stay put. More gunfire and explosions everywhere, then something happens to the driver and Talia takes the wheel but the truck falls down on a bridge. When Gordon checks the cockpit Talia is there, but there's no trace of the driver.
We know that Batman (who doesn't seem to like fire-arms except for those present in all his vehicles) doesn't kill (Nolan's Batman explicitly did and said so in the two previous movies of the saga).
Could somebody clarify what happens to the truck driver during those scenes?
