Definitely, the subject seemed quite human and John was almost getting him. He wondered vaguely if it wouldn’t be easier just to shoot him. He was tired of running already but he had promised Jack not to kill anyone else unless it was necessary. Right, it might still be necessary if the subject was armed. Or if it shapeshifted into something with too many teeth.
With one last effort John jumped forwards and shoved the subject against a wall, falling himself with it. There, he was still in a damn good shape for chasing down aliens, wasn’t he? He tried to say something but was ran out of breath so he just held out his gun and pointed at what looked like a boy.
