There just weren't that many gas stations around back then. And the station in fictional Tabor Heights has the last gas until the New York area. This gives Rosetti a bright idea - take over the gas station, and use it to hold up Nucky's shipment to Rothstein, which can't get all the way from AC to NYC without that refill. The plan works. As is still the case in our world, control the energy and you can control the world - or at least, try to.
Meanwhile, in New York City, Nucky's finding true love - or at least true lust - with the beautiful Billie. When a radiator breaks down, and Billie, naked, gets on the floor and leans over in an attempt to fix it, Nucky says she looks like the White Rock girl. As indeed she does - I remember looking at the White Rock girl myself on soda bottles back as kid in the 1950s, and thinking all kinds of things. But nothing quite as fine as Billie.
Boardwalk Empire is off to a good start this year. No Jimmy, no Manny, but lots other good, gangsterly forces at play - including the return of Nucky's brother, whose ultimate loyalty is still, as ever, in question.
