viewers are speculating that Billy Fletcher is aware of the affair between his wife Dawn Taylor and Joe Tate.

Earlier this year, audiences were taken aback when Dawn (played by Olivia Bromley) began an affair with Joe Tate (portrayed by Ned Porteous), while mourning the death of her father Will (Dean Andrews), who passed away at Christmas.

Seeking solace, she cheated on Billy (Jay Kontzle) with Joe, and despite claiming it was a one-time incident, their relationship has persisted. Kim Tate (Claire King), Joe's step-grandmother, has expressed her doubts about Joe.

She enlisted cleaner and friend Lydia Dingle (Karen Blick) to uncover Joe's secret, resulting in photographic proof of Joe and Dawn's clandestine kisses.

Kim didn't hesitate to confront Joe, cautioning him to stay away from Dawn online and threatening revenge if he crossed her.

In Monday's episode (March 3), Joe informed Dawn of his upcoming trip to Dubai for several weeks. Seizing the moment, they shared a kiss at Home Farm, nearly getting caught by Billy.

However, Joe managed to deflect by claiming there was another woman in the room. Later, Billy returned home and embraced Dawn, while Joe watched before departing, reports Leicestershire Live.

Now, fans believe that Billy is 'onto Dawn and Joe' and 'knows everything'. They also suspect he is plotting a grand act of retribution against the pair.

One fan speculated on an Emmerdale Facebook page: "Dawn has lost the plot, Will Billy find out the truth?"

Another enthusiast quickly commented: "Billy definitely knows something I'm calling it now." A third fan agreed, saying: "I thought that too. I hope so she's horrible to him why is he even with her, he is just her doormat."

Meanwhile, another viewer theorised: "Maybe he's waiting to catch them and will expose them in front of everyone."

Emmerdale airs weeknights on ITV1 and ITVX at 7.30pm
