Following the introduction of her children in 2019, it is revealed that Suki is supposedly terminally ill and wants to reunite with Ash, who left the family following Suki's disapproval of her sexuality and abortion. The character's stories focus on her estranged relationship with Ash and multiple secrets that are revealed in the family.
Suki forms a friendship with Jean Slater when the pair bond over their shared experiences with cancer, but it is revealed that she is lying about her cancer in an attempt to gain her children's trust. Jean discovers the truth, and exposes Suki's lie to her children. Despite their initial disgust with what she has done, Suki persuades Kheerat, Jags and Vinny to forgive her, while Ash refuses to talk to her. During the COVID-19 lockdown, Suki purchases the local corner shop, the Minute Mart. When Vinny knocks Martin unconscious in the Minute Mart, she erases the CCTV footage, and tells the police that Jags attacked Martin, due to disapproving of his relationship with Habiba Ahmed.
