The second season places another killer alongside changes at work, at home, and in Rhiannon’s relationships.
A copycat killer creates an exposure problem for Rhiannon Lewis in Sweetpea’s second season. Someone else’s violence threatens to reveal her own, adding a danger she cannot manage simply by keeping quiet about what she has done. Sky’s second-season premise and character details.
Sky’s season synopsis places that threat among several changes in her public life. Rhiannon has a promotion, a new romantic interest, and a sister preparing to sell the family home. Marina remains on her trail. The story puts these overlapping pressures around the same character, played again by Ella Purnell.
The new relationships have named roles in that setup. Rish Shah plays Gabriel, Rhiannon’s romantic interest. Taj Atwal plays Freya, her new boss at the Carnsham Gazette. Jenny Walser’s Daisy becomes a new friend, while Tamsin Greig plays Liv, AJ’s mother.
The series draws on C.J. Skuse’s novel and is produced by See-Saw Films and fanboy with Sky Studios. STARZ currently lists the second season for early 2027 in the United States. Sky’s second-season premise and character details. STARZ’s current US release window.
