Jhon watched as the Inquisitor considered the question for a matter of seconds. "No" he replied casually, "there is no way of knowing whether the Genestealer contagion has spread to the Uhlan regiment who would then carry it to the ship. Instead, verify that all high value personnel and equipment is aboard and then commence bombardment immediately." The Vice Commodore acknowledged as if he had expected that to be the Inquisitor's answer and disconnected.
The Inquisitor stared at Jhon, assessing what effect it had had on him; witnessing an order that meant the death of an entire world. "That must have shocked you Jhon. While I have absolutely no need to explain my decisions to you, I appreciate that it may help you if you understand my choice. You see Jhon, a Genestealer Cult is a malignant tumor. Once it metastasizes it will infect other organs of Imperial control. It can only be cured by being cut out, brutally and without regret or remorse. I am performing surgery John, for the good of the Segmentum as a whole."
"I also needed to consider the integrity of the information you have brought me, and which has been confirmed by my Acolytes, tells of a very serious deception by very senior members within the Graian Priesthood. The alliance between the Imperium and the Mechanicum is vital to our collective survival. You will not be aware however, that it is sometimes a strained relationship. Nothing can be allowed to threaten that thread which ties together the Throneworld and the Red Planet. No word of this Xenos Heresy must be allowed to leave this world, less it has a destabilising effect."
The Inquisitor then asked him a question that he never would have expected to be directed at him by a Lord of the Segmentum - "Tell me Trooper, can you accept what I have had to do? For the Good of the Imperium. Take time to consider your answer and be honest with me; remember that I have many ways of knowing if you lie." Jhon's brain fizzed with unwelcome energy as a reminder of the Inquisitor's unseen psychic power.
Jhon searched his exhausted mind and found it wanting. He had to provide a truthful answer to a complex moral question that was being posed to him by someone who could kill him instantly with a word, or with a thought. His training, his mental conditioning and his entire childhood had prepared him for a life where he didn't have to question the actions of his superiors, where instead he had clear orders and a clear requirement to carry them out to the letter. With nothing else available to him he fell upon the only other thing that he had been taught in his life - his faith in the Immortal God-Emperor of Mankind.
He remembered the feeling of peace and safety he felt from the brilliant light shining through the stained glasscrete in his Schola Chapel. He let the light fill him up in the darkness of the cell. He thought of the image of the Emperor striking down the foul arch-traitor and the answer suddenly became clear to him. He had literally stared into the face of monsters that day, the Xenos who waited in the stars and beyond the veil. Even faced with that, he knew that heresy and division remained the greatest threat to the Imperium. Didn't the Ecclesiarch teach that? Hadn't every Commissar who had ever been attached to the Psian Pegasi drilled that into him? He was a soldier and if he let doubt cloud his judgement then he would cease to be an asset to the Imperium and would become a potentially fatal chink in it's armour.
With the light of the Emperor filling his eyes and his soul he met the Inquisitor's steely gaze. When he spoke, it was calm and clear and stable, the croak and quaver in his voice was gone and he almost surprised himself with how loud he was. "My Lord Inquisitor I cannot question you. It's not my place, I am a soldier and a faithful servant of the Throne." Despite his confusion, and almost a slight reluctance, he continued "It is merely my role to follow the orders of my commanding officer to the best of my ability and to maintain the Vox equipment in my charge to further my commander's objectives." The Inquisitor stared at him for a long time while Jhon continued to feel the fizzing in the back of his head as he apparently used his mind powers to divine whether or not Jhon was telling the truth.
Eventually a slight smile crossed the half of the Inquisitor's face which could still move. "Very well said Trooper" the Inquisitor stated "In fact I couldn't have put it better myself." The Inquisitor seemed very satisfied now, as if he had found a rare treasure. "That was the other reason that I wanted to speak with you today Trooper. In truth there was little information that you could bring me that I was not already aware of. I already knew of the Graian Genator's treachery and he was dead from the moment he left the landing bay. Sadly I also knew that this world would be forfeit from the reports that your commander Mesarine was sending back to the fleet during your mission. She too is a loyal soldier of the Throne and will be returned to your Regiment." John didn't know what that meant for him, he assumed that it meant execution. "However Trooper, I have the need of an experienced Vox operator within my retenue. My last was unfortunately killed by a Tau pulse weapon while cleansing one of their Agri worlds."
"I needed to know", the Inquisitor continued, "that you had an unshakable faith in the Throne and that you would be loyal when faced with those decisions that an Inquisitor might be presented with during their duties to the Imperium. If you choose not to join me then I give you my word that you will be returned to your Regiment along with Mesarine and your mind will be wiped of this conversation." Jhon again felt that fizzing in his skull, presumably fixing those memories which would need to be expunged. The feeling also seemed to clear his mind further, making the decision seem so easy. "So what do you say Trooper? Will you join me and continue to serve the Emperor, in a new capacity as my personal Vox Operator?"
