USA's Common Law hosts a Lost reunion

The freshman dramedy, which premieres Friday, May 11 at 10/9c, tells the story of Travis Marks (Michael Ealy) and Wes Mitchell (Warren Kole), two sharp LAPD detectives whose partnership becomes so strained that Captain Mike Sutton (Jack McGee) sends them to see  couples therapist Dr. Ryan (Sonya Walger).

Alexander will play Captain Sutton's long-suffering wife Helen, who joins her husband and his detectives in a group session.  In fact, Sutton sends Wes and Travis to Dr. Ryan because she was able to work wonders for him and his wife.
