Ella Purnell is returning to 'Sweetpea' for Season 2, with a first-look image offering a glimpse at the next chapter of the dark comedy thriller. In the newly released still, Purnell reprises her role as Rhiannon Lewis, holding a ketchup bottle as the word “Monster” is scrawled on the wall behind her, hinting at the character’s increasingly complicated state of mind. According to the official logline, the new season follows Rhiannon as she receives a promotion, a new romantic relationship, and yes, there's a new copycat killer who threatens to expose her. As the situation goes out of hand, she begins to question whether her ex, AJ, may have been right about her all along.

For the unversed, the first instalment of Sweetpea ended on a gripping note, setting the tone for Season 2. Ella Purnell’s Rhiannon kills her boyfriend, AJ Pierce (Calam Lynch), after he discovers the truth about the murders she has committed. When he calls her a monster and threatens to leave, she fatally stabs him multiple times. The scene closes with AJ dying in her arms. Season 1 went on to receive positive reviews from critics.
