Earlier this year, Dawn (Olivia Bromley) shocked viewers when she began an affair with Joe Tate (Ned Porteous), while mourning the death of her father Will (Dean Andrews).

Despite being married to Billy (Jay Kontzle), Dawn found solace in Joe's arms and their romance continued despite it initially being labelled as a one-off. Kim Tate (Claire King), Joe's step-grandmother, grew suspicious and eventually discovered the truth about the affair.

Despite her warnings, Joe and Dawn continued their secret relationship. However, last week saw a dramatic turn of events for Joe who is suffering from chronic kidney disease.

In a desperate bid for survival, he conspired with Dr Crowley (James Hillier) to steal a kidney from his uncle Caleb (William Ash). With the police growing suspicious, Joe left for Dubai in Monday's episode (March 31), ending his affair with Dawn.

Now, fans believe that a returning character may expose Dawn's secret actions, reports

On an Emmerdale Facebook fan page, viewers have been voicing their frustration with Dawn's character development.

One fan expressed: "Dawn is really annoying me now! What have they done to the character."

Within the debate, supporters of the show speculated about Debbie Dingle returning to handle Dawn. Another enthused: "I really hope someone exposes her! I'd love someone like Debbie to come back."

Echoing the sentiment for a sensational storyline, a third chimed in: "Catfight in the dales! That would be epic."

Meanwhile, another believer in plot twists hinted: "A Debbie return is looming I've said for ages.."
