(“We used to work for a killer,” one of his employees laments. It’s a professed culture change that brings an entirely different tenor to the office environment. Swapping out Axe for Prince is what really distinguishes this season. Now Chuck has a sparring partner in Prince who can claim to cloak himself in righteousness and not get laughed out of the building. “Billions” has flirted plenty of times with the idea of whether a truly ethical strategy in this ongoing fight could be a winning one. For a man whose greatest heartbreak over the course of the show might be losing a priceless set of first edition Winston Churchill books, Chuck also looks for a fresher way to position himself as the Attorney General for the common man of New York. On both sides of this tussle, “Billions” Season 6 is focused on what it means to go about things “the right way.” Chuck is set on finding avenues that don’t involve the preferred methods of Senior (Jeffrey DeMunn), ones that treated federal law more like suggestions to be discarded whenever they proved inconvenient. funds drama has given “Billions” something of a second life.

However primal that feud between money and the law might seem, though, the Chuck/Axe rivalry had reached a breaking point leading up to Season 6. Back then, he had one particular wealth management operator in his sights, leading to a drawn-out psychological battle with Bobby Axelrod (Damian Lewis) marked by uneasy alliances and scorched-earth tactics. It’s the dynamic set up in the show’s early going, when Chuck Rhoades ( Paul Giamatti) fancied himself a crusader against the excess and greed of the billionaire class. As long as there are people pulling down huge profits on asset manipulation, hostile corporate takeovers, and land grabs, there will be an opposite reaction, however equal. “ Billions” could conceivably go on forever.
