Catherine has them take a polygraph and Hannah fails so they think she is the leak. Hannah digs herself in deeper by calling The Babbler and saying too much. Hannah and Marty go to the office after hours to look for clues in everyone's desks. Robin shows up and admits talking with a reporter from The Babbler. So indirectly Hannah is the leak since she tells Robin and Robin tells the reporter. The next day Hannah admits to everyone that she and Marty went thru their desks. Hannah and Marty have a discussion about lying asking each other questions.
