        Celestia and Luna showed no concern for the discussion at hoof, and that worried Twilight.  They were no more emotional than if they had been deciding whether to order hay fries or a salad.  After a few thousand years of leadership, that was to be expected, Twilight decided.  As much as her view of the diarchs was favorable, was it reasonable to believe that neither had killed before, or at least ordered a killing?  Was it rational to think that the Royal Guards just stood around in their polished golden barding, holding spears and looking handsome?  Surely they had been used before.  Surely, as a herd, their spears were stained with blood.
