In a wonderful, but devastating twist, the opening episode of Peaky Blinders season 6 tells what did happen to helen McCrory's Aunt Polly. Tommy Shelby (Cillian Murphy) is dealing with the consequences of the botched assassination of Oswald Mosley four years since the end of Peaky Blinders season 5, with new conflicts, new tactics, and a new ending for the eternal antihero.
The subject of how the show will cope with the death of primary cast member and Harry Potter alumna helen McCrory was always a pressing one for all of the new and returning characters on Peaky Blinders season 6's cast roster. Polly's departure from the programme, even after retiring from the Shelby Company, was unthinkable, according to her: "only in season 5," she remarked "We're all attempting to flee. But this is something we never do." A character with second sight makes an almost terrifying forecast. Obviously, the prospect of sending her to australia was always a possibility, but Polly was a cornerstone of the organisation.
Season 6 of Peaky Blinders follows up Tommy Shelby's narrative right where season 5 left off, with Tommy out in the woods with a pistol to his head. The vision of Grace begging him to let go finally convinced him to commit suicide, which is obviously a big matter, but Arthur removes the bullets. Tommy returns home to find Barney and Aberama Gold's deaths, as well as a mystery third victim wrapped in white blankets and dumped outside his front door. A phone conversation from ira leader Captain Swing says that they were responsible for foiling Tommy's attempted attack on Oswald Mosley, and that they used the opportunity to "restructure" Tommy's group by executing Barney and Aberama.
