"The debt owed," Aragorn says sternly, "does not cancel that owed to the sailors you waylaid, to the lives you would have taken given your chance. Our people have suffered much of late. I would not have their grief compounded, would not have them harried by corsairs, no matter what service their captain has done in the past." Letting go of Arwen's hand, he gets to his feet, looking down at Jack. His voice softens, but only a little. "As a man, I am with Faramir; I am grateful for what good you have done, for the Lady Éowyn is dear to us all. But my duty is to the land, and to its people. I cannot let you go free."
