Now that a fourth season is assured, we needn't worry that too much harm is going to come to 'Boardwalk Empire's Nucky Thompson, even as unstable gangsters like Gyp Rosetti (Bobby Canavale) take every excuse to start a conflict.  Certainly after his percieved slight in "Bone For Tuna" the heat is quite literally on in their growing conflict.  So, what do the first official clips from follow-up episode "Blue Bell Boy" reveal?  Who's next in danger of facing Nucky's wrath?

This Sunday night sees the continuation of 'Boardwalk Empire's third season with "Blue Bell Boy," as the conflict between Nucky and Gyp Rosetti is bound to boil over following the brutal murder of the Tabor Heights sheriff.  The first official clips from Sunday's episode lack Gyp himself, but still show Nucky clearly on edge as he becomes antagonistic toward Owen.  Not only that, but over in Manhattan Charlie Luciano has plenty on his own plate as he faces down a tense meeting with rival gangsters.

With so many episodes left in the season, can Nucky and Gyp come to any kind of peace?  What about the conflicts brewing in New York, or with Van Alden and his new cronies out in Chicago?

Check out the clips from Sunday's all-new 'Boardwalk Empire' "Blue Bell Boy," and let us know what you think in the comments!
