Emmerdale fans have been sickened over recent weeks as Moira and Nate continue their sordid affair.
Despite being married to Cain, Moira has been playing away with farm hand Nate for weeks.
With Cain away, the pair have ramped up their steamy sessions in the caravan - with Moira even giving up watching her children play football to be with Nate.
Viewers are dead against the affair and have been wondering how the pair will inevitably get found out.
And they've now come up with a theory - that Moira will get pregnant by Nate.
Despite Moira wanting to keep things casual between her and Nate, fans think she might get caught out and become pregnant - which will lead to Cain finding out about the pair's affair.
And lots of fans took to social media to share their theory.
@primmacoffee said: "Nate and Moira again FFS bet she will end up being pregnant or something."
Hannah said: "Moira is going to get pregnant and that is how Cain will find out."
And Gaynor Chambers said: "Wouldn't it be so funny if Moira falls pregnant with Nate's kid but says it's Cain's!"
*Emmerdale continues at 8pm on ITV tonight
