The moment the heretics revealed themselves, Jack drew his blades and eyed the poor souls with malice. He discerned that they had noted his presence, and so immediately ran ahead to unleash holy retribution upon these traitors. However, he did not shout or scream, nor did he yell some battle cry of his regiment or any such thing, instead charging forward with a steely, watchful gaze. Having chosen his prey, he twirled his mono-sword and thrust his second, cruel looking blade into the heretic's heart. He peered into the man's eyes, absorbing all of the fear and hatred residing within, then promptly ripped his sword out with an overall unnecessary amount of flourish and bloodlust after the moment had passed, bits of shredded armor and flesh flying towards the heavens. He kicked the cadaver to the ground, then glanced around for another target. 

Upon seeing the crazy medic charge into a nearby heretic and impale a man with his bayonet, Jack raced over to the dying foe, holding his swords at the ready. As he rapidly approached, he began to hiss and growl with a primal yet contained fury overcoming him. He pounced upon the doubled up heretic, ramming a blade into his neck, causing even more blood to spurt onto Mikail's shotgun. With a wrathful howl, he tore the sword off of the heretic's neck, leaving only a thread of flesh connecting the man's head to his shoulders. "DEATH WALKS AMONG YOU!"
