rebecca ferguson appears in the Peaky Blinders film as Kaulo, a spirit medium revealed to be the identical twin sister of Zelda. That revelation reframes Zelda’s backstory — from the theft at the Appleby Horse Fair to a denied hospital bed and an avenging son — and places Kaulo at the centre of the franchise’s next chapter.
What If Rebecca Ferguson’s Kaulo Returns?
The film introduces Kaulo as a Romany figure who seduces Tommy Shelby while apparently channelling Zelda’s spirit and urges him toward reconciliation with his son. Rebecca Ferguson told interviewer Michael Hodges, “I never say no. ” She added that Kaulo was essential for the film and suggested that characters do not always need continuation, commenting that viewers can “be satisfied with not being satisfied. ” The narrative ends with Kaulo at Duke’s side as the new head of the Shelby clan, positioning her as a potential matriarchal successor to figures previously central to the family’s power dynamics.
What Happens When Zelda and Kaulo’s Histories Collide?
The film and earlier series material connect a set of discrete events: Zelda once stole a watch from Tommy at the Appleby Horse Fair, spent a night with him under a hazel tree, and later fell ill. Zelda’s father shot Tommy with a squirrel gun; Tommy was not injured and left for the trenches. He did not see Zelda again. Zelda later died after being denied a hospital bed in Bridgnorth. Tommy only learned of his son decades later when he was introduced to Duke Shelby. Duke, raised working at a fairground and initially a thief, was taken under Tommy’s wing, then moved into the darker side of the business. After learning of his mother’s fate, Duke murdered the person who had refused her a bed. In the present timeline of the film, Kaulo encourages Duke to claim Tommy’s position by killing his father; Duke instead chooses Tommy but nevertheless ends the story with Kaulo beside him as leader.
What Is Likely to Change — Scenarios and Stakes
- Best case: Kaulo’s presence stabilises the Shelby succession, giving Duke a guiding matriarch and resolving long-running family fractures without renewed bloodshed.
- Most likely: Kaulo remains a pivotal, ambiguous figure whose spiritual claims and political influence continue to complicate loyalties within the family, producing fragile alliances and power plays.
- Most challenging: Kaulo’s interventions deepen internal conflict, with attempts to seize Tommy’s legacy provoking further violence and a reordering of the clan under a new, less predictable leadership.
These outcomes follow directly from the film’s closing positions: Kaulo as an influential actor at Duke’s side, Tommy’s complicated history with Zelda, and the revelation that Kaulo is Zelda’s identical twin. The actress described the relationship with Duke’s actor as one that allowed Kaulo to set limits — “Kaulo is the only person who can say, ‘Stop’ and he listens” — highlighting how her influence could check or inflame Duke’s volatility.
Uncertainties remain: whether Kaulo will be written forward beyond this film, how other family figures will respond to a newly assertive matriarch, and whether Duke’s choice at the film’s climax represents long-term consolidation or a precarious pause.
Readers should take away three points: the film explicitly reassigns lineage and motive by revealing Kaulo as Zelda’s twin; key acts in the past — the theft at Appleby, the denied hospital bed in Bridgnorth, and Tommy’s absence after the war — are now drivers of present conflict; and rebecca ferguson’s comments leave open the character’s future while confirming Kaulo’s centrality to the story. Watch for Kaulo’s role in shaping the next power balance within the Shelby clan.
