Nathaniel rushes in blindly, in the hope that he and his companions are the foretold saviors of this town, rushing along to keep up with the girl... As she pauses at the edge of the field, he puts a hand on her shoulder, and gestures softly to bring her to a crouch, then crouching himself, trying to remain somewhat concealed in the wheat, peering out carefully at the farmhouse.
He whispers: "You should stay back, and run again to the keep at the first sign of trouble... I promise here and now my life that I will not allow your family to come to harm, and that includes you: So for the sake of this vow, please heed my words." He meanwhile begins to unsheathe his sword, attempting as greatly intense and heroic look as possible, if only to ease this young girl's fears.
As the others arrive, he lays out a plan: "I suggest we approach in a tight formation, as we should expect no more than one adversary, and it is more apt to surprise us than we are to lay any sort of surprise on it -- the warriors among us in a wall around those with other skills, looking to all sides. If the family is in no apparent danger, then they take the center as we escort them back to the keep... Would you all agree with this approach?"
