In the closing scene of the episode, Cain Dingle (played by Jeff Hordley) was seen watching a crime programme.
To his horror, he saw CCTV footage of his own daughter (Charley Webb) putting her children in a car at a petrol station.
The presenter of the appeal show then announced that police were looking for the woman getting into the car.
The voiceover was heard saying: “The vehicle is thought to have been involved in a robbery and subsequent hit and run.”

The episode ended before it was revealed what had happened to the person who had been hit by the car or whether it was Debbie who was driving.
Viewers felt mixed emotions about the scene, as they were glad to see the fan favourite back but concerned about what sort of trouble she has got her self into.
One social media user said: “Debbie!! But oh gosh a robbery that ain't good! #emmerdale.”
