Having arrived in the Arctic, with no knowledge of what to do next, Clark lets the Crystal of Knowledge do all the work. With the newly formed Fortress of Solitude, Clark begins the task of fulfilling his true destiny and stopping the coming evil with the help of Jor-El.

Chloe Sullivan's mysterious disappearing act in the caves, and reappearance in a hospital in the Yukon, has Lex Luthor growing ever suspicious of Clark and his secret. Clark meets one of his college professors, Professor Fine, who has a few secrets of his own. Aquaman and Cyborg stop by Smallville, and Chloe gets a job at the Daily Planet, starting at the bottom.
