I'm sure it will be on DVD soon.
Last night's episode was more transitional and a bit too soap-opera like for me but of course you can't have "action" every single episode.

I think it's pretty clear that Jimmy's "son" is not his.
Why would Jimmy's mother make that offer about Jimmy's "child"? That came out of nowhere. Or maybe she was just feeling guilty as to how she had raised Jimmy and saw through the younger woman's story of having to meet a "friend" down on the boardwalk since it was a story she used to use.

The agent's response to the lawyer questioning the raid was funny.

Margaret's willingness to do what she did simply as a way to get sexual leverage over Nucky was intriguing. Presumably Nucky is aware of this which is why it ended like it did. The interesting question is what happens next.

Could they be setting up a Fredo like storyline with Nucky's brother, the sheriff? He definitely seems to have more resentments than he should.

Also Legs Diamond was an associate of Rothstein's just as Luciano was. I wonder if he will show up in the series at some point.
