Moira Dingle will start to smell a rat over her husband Cain's bond with his ex-partner Charity.
Charity is currently serving a two-year prison sentence for perverting the course of justice, but that won't stop Moira's insecurities from flaring up over the next few weeks.
Before heading to jail, Charity told Cain that she still had strong feelings for him and she later reaffirmed this when he paid her a visit.
In a video released on Emmerdale's Facebook page, series producer Kate Oates teased: "Since Charity went to prison, Moira has been the one looking after Noah at Butler's with Cain. Over the next few weeks, we're going to see Moira start to wonder what actually went on with Cain and Charity, especially those little chats that they had before Charity went to prison.
"I'm not going to say too much about that because it is more of a summer story, but just watch as Moira starts to grow a little bit more suspicious and see how Cain handles that."
Charity's time away from Emmerdale was written in because Emma Atkins, who plays the scheming character, has taken maternity leave. She welcomed the arrival of a baby son in March.
Oates has previously confirmed that Charity's storyline will be revisited sooner than expected, as viewers will learn more about the scam she has been cooking up while behind bars.
Speaking last month, Oates said: "The eagle-eared amongst you may remember that when Cain went to visit Charity in prison, she told him that maybe she had a little bit of a scam up her sleeve that might give her a reduced sentence.
"We're going to be revealing what that is really soon, and it's going to have a huge impact on Debbie and the rest of the Dingles."
