After some investigation,
Alfie revealed that he was suffering from skin cancer, which he attributed to the poisonous gas used in the Great War; Alfie had intended for Tommy to discover his betrayal, track him down, and kill him so Alfie could die on his own terms, rather than the Mafia.
This information became useful in the finale of that season when Tommy went to kill Alfie because of the bad blood between them. Alfie seemingly accepted his fate, stating that "there's an honorable reason now to pull that trigger" and he even forced Tommy to shoot him in self-defense when Tommy showed hesitation.
Alfie's story holds a double meaning which Arthur realizes when Alfie tells him the goat's name is Tommy Shelby. This is the first time Alfie betrays Tommy in favor of Sabini's crew. The night ends with all the dinner guests dead (including the goat) and Arthur in jail for their murder.
Though Alfie doesn't say what type of cancer he has, Schiavo tells Chap that the "Peaky Blinders" team did have a specific kind in mind. "From season 1, Solomon has lung cancer," she says while explaining the addition of psoriasis, "but we wanted something else that showed physically on the exterior.
Most notably, in the fourth season finale his character Alfie Solomons got shot in the face by on-and-off ally Tommy (Cillian Murphy), only to apparently live to reconcile with the show's antihero another day.
Both an enemy and ally of the Peaky Blinders, Alfie Solomons, played brilliantly by Tom Hardy, is a volatile and dangerous force whose loyalty changes based on his own ambition and greed.
However, it turns out that Alfie had an ulterior motive with his betrayal. He had just found out that he had cancer, and he knew Tommy would kill him before the cancer did.
Alfie was in terrible pain and dying from cancer and knew that if he messed with Tommy (-threatened his life) then Tommy would kill him, which at the end of the day was exactly what Alfie wanted.
Alfie is the former-foe-turned-sort-of-friend who Tommy shot in the face at the end of season four then returned at the end of season five to help the Peaky Blinders bring down Mosley.
Cillian Murphy, who plays Tommy, was asked about this very topic during an interview with BBC Radio One. The actor explained: "That comes from the fact that the cigarettes, we cut the filter off or do we leave the filter on I cannot recall, but anyway if you don't rub them across your lips initially, they will stick.
Michael especially lacks Tommy's cool and calm demeanour and his 'Brains". He is then driven solely by revenge for Polly's murder, which he blames completely on Thomas despite the fact that Thomas didn't even murder Polly and Tommy was equally as devastated by Polly's deaths as Michael was.
8 Aberama Gold
In season 5, Aberama got married to Polly, but their happiness did not last for last. First, Aberama lost his son to the Billy Boys, and then he began to plot the assassination of Jimmy McCavern, but before he could complete the task, Aberama was killed by the IRA.
Alfie Solomons: Solomons is based on a real-life gangster named Alfred Solomon. Like most Tom Hardy characters, the accent is purely of his own invention. No one but Tom Hardy would ever talk like that. Sir Oswald Mosley: The founder and leader of the British Union of Fascists was a real political leader.
The untimely death of Helen McCrory, who played Polly, forced Peaky Blinders to reshape itself. “When we found out that she was ill, especially during COVID, Steve [Knight, the creator of Peaky Blinders] had to choose a direction to make the plot make sense,” Peaky executive producer Caryn Mandabach tells Tudum.
How did Tommy find out that Billy betrayed him? After Jack Nelson violently forced Billy Grade into becoming an informant for his operation, somehow Tommy found out (possibly because Billy was passing information to Gina Gray, whom Tommy had surveilled and was blackmailing over her adultery with Oswald Mosley).
Nelson is a fascist sympathizer and Tommy agrees to introduce him to Mosley, his fiance, Lady Diana Milton, and McKee, who agrees to promote fascist causes in Ireland. Tommy later sleeps with Milton, who then tells his wife, Lizzie. Tommy's young daughter Ruby gets sick with tuberculosis.
The sapphire was then thrown into the river, with Evadne cursing Tommy Shelby in retaliation for her daughter's death. She vowed that any daughter of his would also die at the age of seven.
That suggests that Tommy's handing on a mixture of "you're up, kidda" business stuff and straightforward "I'm gonna die, kidda" stuff. Certainly, that's what the direction and editing hints at. We see young Charles, buttoned up in his grey coat, looking distinctly miffed.
The Shelbys Go To Jail
At a family gathering at his place during the last season three episode, Tommy watches his family be arrested as part of a deal he made with people more powerful than Economic League. While the character assures everyone that he has a big plan in mind, the family's trust is already broken.
Peaky Blinders season 6, episode 5, confirmed that Billy was the one who leaked Tommy Shelby's assassination plan to the IRA. Billy meets his end at the hands of Duke, after Finn refuses, in the Peaky Blinders season 6 finale.
Aberama believed Johnny Dogs (Packy Lee) had betrayed the Shelby family because he was one of the few people who knew where they were camped. Tommy, however, insisted he was wrong. Truth be told, Johnny Dogs is far too loyal to betray Tommy.
The most powerful member of the Peaky Blinders was a man known as Kevin Mooney. His real name was Thomas Gilbert, but he routinely changed his last name. Other prominent members of the gang were David Taylor, Earnest Haynes, Harry Fowles, and Stephen McNickle.
Thomas Shelby
As the leader of the Blinders, he held the most power, and his business dealings with the right (or wrong?)
Oswald Mosley is one of the two main antagonists (alongside Chief Inspector Campbell) of the BBC Crime series Peaky Blinders, serving as the main antagonist of Season 5, and the overarching antagonist of Season 6.
