This episode originally was the series finale but the ratings swerve too high for only four seasons so they made another season
Up until 2002, California had a so-called "Son of Sam" law that prevented convicted felons from profiting off their crime like Hank did from penning the screenplay of the manuscript Mia stole from him. If the state Supreme Court hadn't struck down the law, Hank would had to have donated all proceeds from his work to a victims' fund, since his novel and subsequent movie were a fictionalization of the statutory rape.
