Boardwalk Empire Season 2 DVD gives us a dark exploration of guilt and consequence, it is Nucky's refusal to repent, while others wallow in attrition. We can see more surprise in the Boardwalk Empire season 2, the most important of which has been the apparent usurping of Nucky's power by upstart Jimmy Darmody, through the puppet mastering of his father, Commodore Louis Kaestner.
Jimmy attempts to make allies with powerful criminals, such as Arnold Rothstein and Manny Horvitz. Although Rothstein does not make a business deal with Jimmy, Manny takes a liking to him. Their relationship eventually turns sour, however, and Jimmy makes an unsuccessful attempt on his life.
Margaret meets Owen Sleater, who has come from Ireland to assist Nucky. She is attracted to him, but does not act upon these feelings immediately. She eventually sleeps with him after visiting her family in New York. When her daughter, Emily, contracts polio, Margaret is plagued with guilt over her past sins, which include living with the man who ordered her husband's death.
Jimmy reluctantly orders a hit on Nucky upon the insistence of Eli. This event, along with his upcoming trial, forces Nucky to resign. Jimmy has a short-lived and unsuccessful reign as boss of Atlantic City, while Nucky uses the time to get out of his predicament. Manny Horvitz, meanwhile, murders Angela, Jimmy's wife in revenge. Rothstein sets Nucky up with his lawyer, while Van Alden flees to Cicero, Illinois after the death of his former partner is brought up, and Jimmy, high on heroin, murders the Commodore.
