A new teaser for the HBO drama's third season (spoiler alert!) replays in super slo-mo Nucky (Steve Buscemi) gunning down his one-time protege Jimmy Darmody (Michael Pitt), who betrayed his former mentor in a political coup. It's dark and moody, which suggests Nucky will feel the reprecussions of the murder for a long time to come.
The falling boutonniere could represent his political career, which is likely to be a rocky enterprise in Season 3. The clip ends by showing the words Jimmy said to Nucky in the show's very first season, "You can't be half a gangster."
Nucky ulitmately picks up the pistol, so I'm guessing he has chosen to be a full-time gangster. What do you think?
Season 3 of "Boardwalk Empire" premieres at 8 p.m. Sept. 16 on HBO.
