Why The Winner Won.
It was all predestined, of course. They don't call them The Fates for nothing. Here is an analysis of why they chose Lina:
Patrick: A true warrior with the strength of many. He even looked the part of a hero. But near the end, when he described the competition involving the extraction of the egg from the pit, he misled the deliberators in hopes of saving Bonnie. A true hero must be true to the truth wherever it leads him.
Shondo: A focused competitor with great heart. It was he who championed competition, exhorting the others to push each other. But near the end, he referred to himself in the third person. A true hero can and must have ego, but he must believe in himself, not in a myth that surrounds him, even if self-created.
Andrew: A competitor who seemed to grow as the competition progressed. One might think The Fates--looking into his heart--knew that he stood behind Lina because he feared (the competition represented by) Patrick. But he said it best himself: for a moment, he let the lure of power avert his gaze from the true quest.
Lina: From the beginning, Asgard said his goal was to teach them. It was Lina who learned the most important lessons. In the final competition, she was cool-headed, using the patience she had learned in previous competitions. It did not matter that she was smaller. On occasion, even Hobbitses have become The One True Hero. And so The Fates smiled on her. Or at least the blonde did, despite herself.
Perhaps you noticed that (in my review) I chose Lina as my champion at the end of the first episode. Luck plays its part in everything.
