He'd hit Bob, but the arm remained mainly intact, his shot had only messed up Bob's attack on Serina and Nolan, maybe it would be enough. That thing that had done something to Bob flew back, seeming to retreat a little, and Kall saw his chance to hit it. He brought his rifle up quickly, putting the thing's small figure in the distance between the cross hairs, and opened up, firing several times hoping to hit it, not sure if he could even hurt it.
