In March 2014, Dot is told by the police that Nick has died of respiratory failure from a heroin overdose the previous week. One of the police officers who breaks the news to Dot is Nick's son Charlie Cotton, although it is later revealed that he is impersonating a police officer. Charlie explains that he was conceived from a brief marriage Nick had with his mother Yvonne. During the funeral, Charlie and undertaker Les Coker prevent Dot from looking in the coffin. Dot is suspicious and invites Yvonne to tell the truth and she assures Dot that Charlie is her grandson. A few weeks later, Carol Jackson asks Charlie for advice, when he leaves his phone at her house, she answers a call and discovers that Nick is still alive.
