Sweetpea Season 2: Ella Purnell's Crime Thriller Returns With a Moral Reckoning
British actress Ella Purnell is set to return in November 2026 for the second season of Sweetpea, the crime thriller that critics have dubbed a blend of Dexter and Breaking Bad. The six-episode series, which premiered on Sky Atlantic in 2024, tells the story of Rhiannon Lewis, a quiet administrative assistant who discovers a talent for murder after being pushed beyond her limits. For Gaborone audiences who appreciate character-driven drama with moral weight, this show offers a compelling examination of how ordinary people can lose their way.
What is Sweetpea about?
Rhiannon Lewis is a meek and overlooked young woman working as an administrative assistant. When her father dies and a series of misfortunes pile up, she reaches a breaking point. After a humiliating encounter with her former school bully, Rhiannon is accidentally urinated on by a drunk man while walking home. She impulsively stabs him and disposes of his body in a canal. From that moment, a killer is born.
The show draws clear parallels to Dexter, as Rhiannon becomes a selective serial killer who targets people she believes deserve punishment. Yet it also echoes Breaking Bad in its portrayal of an unremarkable person's gradual descent into criminality. Unlike Walter White, whose choices were calculated, Rhiannon's actions are reactions to being pushed too far too many times.
How does Rhiannon differ from other TV killers?
Most television shows about serial killers introduce protagonists who are already experienced in their craft. Dexter Morgan and You's Joe Goldberg are established killers from their first scenes. Rhiannon is different. When viewers first meet her, murder is the furthest thing from her mind.
Her transformation mirrors Walter White's arc in Breaking Bad. Just as Walt's terminal cancer diagnosis and financial desperation led him to a life of crime, Rhiannon's personal losses and humiliations push her toward violence. However, where Walt made a calculated decision to enter the drug trade, Rhiannon's first kill is impulsive, a reaction to a moment of profound degradation.
What can viewers expect from Sweetpea season 2?
Season 1 served as an origin story, but season 2 will deal with the consequences of Rhiannon's actions. The series is based on CJ Skuse's 2017 novel, and the first season functioned as a prequel to the book's events.
In the upcoming season, Rhiannon faces two major threats. A copycat killer is attempting to expose her, and she is still reeling from her boyfriend calling her a monster after discovering her secrets in the season 1 finale. The show promises to explore the psychological toll of a life of crime, a theme that resonates across cultures.
Why does this show matter for conservative audiences?
Sweetpea offers more than mere entertainment. It presents a cautionary tale about the erosion of moral boundaries. Rhiannon begins as a sympathetic figure, a woman who has been overlooked and mistreated. Yet her choice to take justice into her own hands leads her down a destructive path. The show asks difficult questions about personal responsibility, the consequences of revenge, and the thin line between victim and perpetrator.
In an era when many television programs glorify antiheroes, Sweetpea stands out for its willingness to show the ugliness of violence and the weight of guilt. Season 2 appears poised to deliver a moral reckoning that viewers of all backgrounds can appreciate.
Purnell, known for her roles in Fallout, Arcane, and Yellowjackets, continues to demonstrate her versatility as an actress. Her portrayal of Rhiannon Lewis is both unsettling and compelling, a performance that reminds us of the dangers of losing one's moral compass.
Sweetpea season 2 premieres in November 2026. For those who have not yet seen season 1, now is the time to catch up on the crimes of Rhiannon Lewis.
