With the ripples of the rock in a stream, these lives are so connected that people who never met Clark still felt the changes because he was not in the picture. Lois is stirring up a whole hornet's nest of things by looking for this person who is not alive right now. But the sting will not be as bad as the gaping hole left without Clark in the picture.
