Melissa Keel was a Human female who lived during the 24th century. She was the sister of Walker Keel and Anne Keel. In 2364, when Walker told Jean-Luc Picard that his brother introduced Beverly Crusher and Jack Crusher, Picard corrected him, saying he didn't have a brother, but rather two sisters named Anne and Melissa. The lie was Keel's attempt to get Picard to correct him, and by doing so, prove he really was who he claimed to be. (TNG: "Conspiracy" ) This character was only mentioned in dialogue.
