Shattered

S3, E8: Lex locates Morgan Edge (now played by Patrick Bergin - "Sleeping With the Enemy")--who has undergone facial reconstruction--and gets him to admit to criminal dealings with Lionel. But before Lex can report his knowledge to the authorities, someone tries to kill him at the mansion. After barely surviving, Lex flees and asks Clark for help. However, when Clark returns to the mansion to investigate, he finds nothing amiss. He begins to wonder if what Lex described really happened, especially after Lionel discloses that Lex has had a psychotic breakdown and must be institutionalized.
