However, he was "reprogrammed" by Jor-El and returned as Kal-El, with no knowledge of Clark's life and intent on fulfilling his destiny to reunite the Stones of Power. Martha was astonished when, out in the barnyard, Kal-El simply flew away. Martha contacted Virgil Swann, who sent his associate, Bridgette Crosby, along with a fragment of black kryptonite. When Martha exposed Kal-El to the fragment, Clark was able to overpower Kal-El and return to his normal self. Simultaneously, Jonathan awoke from his coma.
