The Confessor had taken the end of the fighting calmly, reloading his arms and putting them into their slings or holsters. He moved cautiously to Lisbeth, in an almost protective manner knowing that she had to fight the man of her dreams in a proper state of rest with holy arms at her side, rather than in a state of injury or exhaustion after being ministered to. Horacio was not about to tell them their business, and that she shouldn't chase after heretic aboard but the man had seen enough to know caution was best exercised here. 

"I concur with the Sisters. The foe must be slain with utmost urgency lest this all be part of some grand plot." He said quite simply, reading from a prayer book he got from some recesses of his clothes. The Confessor didn't bother to speak much more, not having any further input. Instead he went forth to the fallen armsmen and traitorous humans about. He prayed for the souls of all, not asking for forgiveness or salvation but rather fair judgement - which in the case of good men would equate to the same thing. For the traitors however, the Emperor had much penance planned in the afterlife. 

Then he returned to his comrades, somewhat more solemn looking. Whatever input the others had he didn't bother asking about. He was a leader, but not a commander and this would reflect quite simply on his actions. Thus he would go along with whatever was planned upon, his duty done either way.
