Leif would simply dispatch second silver bolt into Ronald, this time his aim was the heart.
"Oh, my... I forgot..." - with that young man would walk over and pierce Ronald's skull with retractable bayonet that jumped out of the crossbow front.
"It went past my mind that traitors and those offering bribe have no heart." - he would straighten up and move back in front of the commissar, loading final bolt into the weapon, and holding it in hands this time so blood soaked weapon does not smudge the polished table.
