Poor Paddy has been left hurt and confused by his wife's increasingly erratic behaviour, blaming alcohol or maybe even an affair.
But he has so far failed to guess that Rhona has actually been battling a fierce addiction to prescription painkillers for months.
"He gets the feeling that she doesn't love him anymore," Dominic explains.
But Paddy is in for an ever bigger shock when he finds out exactly what's been going on with Rhona and Vanessa - a friend and colleague who he thinks has been supporting his wife.
As viewers know, Vanessa has confessed to being in love with Rhona - however, it's unclear whether her feelings are really reciprocated or whether the desperate vet will simply do anything to keep her on side and get her next fix.
In a bid to convince Vanessa - who has been supplying her with pills in a well-intentioned bid to wean her off them - that she needs her around, Rhona leans in for a kiss. Just as Paddy walks in.
"I think he's utterly, totally, completely shocked. And more than that, confused," Dominic reveals.
But will the whole dark truth of Rhona's addiction finally come to light?
According to Dominic, Paddy does find out eventually, but "it's a rocky old road ..."
