Clark's biological cousin Kara feels a longing toward her home of Krypton, and knows that the only connection that she can still make with her home is by recovering the crystal taken from her destroyed ship by the government. She goes on a journey to discover the crystal's whereabouts, and finds it in Washington, D.C. However, when Kara locates where the crystal should be, it is gone! The government then captures Kara and injects kryptonite in her bloodstream as a sort of truth serum to learn about her past. As Clark arrives to save her, a touch to her injection allows him to see the same thing.
