"Who is the Real Don Blake? The Answer At Last!"
Dr. Don Blake ponders this question as he clears his mind and focuses on Asgard, and sees through Thor's eyes. Thor places the question to Odin, who reveals the secret. As a youth, Thor lacked only one virtue, humility. He could not learn it as the all-powerful God of Thunder, so Odin stripped him of his godhood and put his conciousness into a being that Odin created, a lame, compassionate physician, so that Thor could learn. Blake's discovery of Mjolnir was all pre-engineered by Odin to re-awaken the Thunder God when he had learned what he must.
