It was a showdown two seasons in the making, and finally in this week's season finale, it was Nucky versus Jimmy on 'Boardwalk Empire' (Sun., 9PM ET on HBO). After all the damage and ruckus Jimmy has caused Nucky over the past season, it was inevitable that it would come down to the two of them.

Jimmy was once Nucky's right-hand man. He was the heir apparent to Nucky's bootlegging throne in Prohibition-era Atlantic City, but it just wasn't enough for Jimmy. Unfortunately, his ambition was more than his intellect could handle, and he found himself in over his head.
