As Aragorn said at Helm's Deep, "There is always hope. "
In one thing you have not changed, dear friend," said Aragorn: "you still speak in riddles. " "What? In riddles?" said Gandalf. "No! For I was talking aloud to myself. A habit of the old: they choose the wisest person present to speak to; the long explanations needed by the young are wearying.
Tolkien can say that Aragorn became king and reigned for a hundred years, and he was wise and good. But Tolkien doesn’t ask the question: What was Aragorn’s tax policy? Did he maintain a standing army? What did he do in times of flood and famine? And what about all these orcs? By the end of the war, Sauron is gone but all of the orcs aren’t gone – they’re in the mountains. Did Aragorn pursue a policy of systematic genocide and kill them? Even the little baby orcs, in their little orc cradles?
Thus Aragorn for the first time in the full light of day beheld Éowyn, Lady of Rohan, and thought her fair, fair and cold, like a morning of pale spring that is not yet come to womanhood. And she was now suddenly aware of him: tall heir of kings, wise with many winters, greycloaked, hiding a power that yet she felt. For a moment still as stone she stood, then turning swiftly she was gone.
