"Wissenschaftler Schein - as you were," states the Commander, 'Fisk, T', from the train, who apparently heard you talking, stopped with a cup of something, and is now waving those of you who start to your feet back to your seats, "don't let me stop you from eating - Doctor Schein, he is a sociopath and a psychopath. This I am sure of from knowing him. And yes, he is a genius, but he is also a scientist of only genetics and biochemistry. So he does not know how to make guns better, only how to make people better. To be fair," Fisk admits, "he did succeed at making people better. He is not only chicken in hen-house, though - just one who thought crazy things and did many experiments and killed many people in order to come up with crazy successful break-through. Which," he points out, "still kills many people. So yes, other things are being tried, all over the world." He glances across the eleven of you (nine chippies, two thugs) then nods courteously and continues onwards.
