Yes I watched the second episode. It was good. With the exception of Ron Pearlman, I can't think of another actor who does "world weary" or "irritated" as well as Buscemi does.

In the second episode we got to see more of Capone and his temper, how Nucky makes his money and how corruption can get a hold of some people.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
