The federal agent who raided Capone's warehouse (the one run by Van Alden and Nucky's brother) was Elliott Ness.
Totino (the guy who's body was delivered to the whorehouse at the end of the episode) had his ear cut off. That's Nucky's bodyguard's signature (no surprise, I just didn't notice that the ear was cut off before).
Didn't notice it before but the guy playing the Commodore in Nucky's flashback scenes really looks like a young Dabney Coleman who played the Commodore in Seasons 1 and 2.
