James was leading the Sororitas Sister as she strode about, one of that nature and armament was bound to be a problem quickly after she saw the retinue enter the Museum.

As predicted, she entered the museum after them,  unable to get the message out in time he simply followed her in his scope, waiting to fire. She was not part of the assigned retinue and was therefore a viable casualty in his eyes. However, as shit hit the fan inside the museum, James's mind diverted from the Sister and began picking off any statues he saw moving towards the retinue. Though he only took down one or two before the psyker did a number on the area. "Psyker how stupid are you? You no doubt just pissed off every tainted thing within the area. I do not have the ammo for this kind of prolonged combat." then he found the frequency the Sister was on and began to speak with the most commanding tone he could muster. "Sister of the Adeptus Sororitas, I am James Mathias Dyrdunn of the Officio Assassinorum, Temple Vindicare, you are firing on an Ordo Malleus Inquisitor of the Imperium and are ordered to stand down at once, failure to comply will result in your immediate execution. Do not test me, I never fail." He sound commanding, but as cold as ice as he spoke. He did not care what the Psyker or the Sister thought of him, all he needed for each was one shot anyway. Now he kept scanning the area, waiting for more statues, more daemons to purge. Also sometimes peeking at the Sister and Psyker, waiting for one of them to make another dumb decision that endangers the life of the entire retinue. Each moment felt like a few hours to him as he waited. Each corner seemed to hide a possible threat, his finger waited to squeeze the trigger and earn a few more kills for the night.

Tonight was a glorious night to purge.
