After a schoolmate claims to be an alien and seemingly backs it up by using heat rays, Clark investigates and begins to believe that the guy is from his home planet Krypton. Meanwhile, after Helen discovers a locked room in the mansion she demands to know what is behind it, forcing Lex to come clean about his investigation of Clark. I thought it was stupid to have some guy thinking he's an alien given the fact that Clark is the last of his species. Other than that, it was an entertaining episode.
