It wasn't hard for Londo to notice when something out of the ordinary was happening during the mustering; While such things were naturally chaotic, watching a man push and shove his way through the crowd in a clear attempt to escape from two men pursing him caused a disruption to the process of organizing 'solders' that couldn't be missed. 

Giving one last barked order to some lay about before sighing and muttering out loud to himself about how organizing these peasants was like herding cats without them trying to kill each other, he stalked the disturbance through the crowd with the single minded self assurance that others would move to get out of his way and a look in his face that promised that he was feeling socialistic with his ire and was more than prepared to unleash it on anyone stupid enough to draw his attention. 

As he made his final approach towards what was clearly devolving into a knife fight, a smile that would have looked right at home on one of the many daemons of the warp started to grow on his face. "Oh good, it's always nice when solders decide to step forward and volunteer for dangerous scouting missions. Saves having to write out the disciplinary reports or calling for a commissar to waste their time on a bunch of worthless dregs who aren't worth the las rounds it would take to execute them for trying to kill their fellow solders. STAND AT ATTENTION WHEN YOUR SUPERIORS ARE ADDRESSING YOU, YOU SMALL MINDED WASTES OF HUMANITY!" Londo started off with an almost friendly tone before he started to bark barked with the tone of enraged command as he glared at all three men who had dared start a fight with each other and disrupt the marshaling of an imperial armed force, even if just in a minor way.
