Matthew Wolfenden says David Metcalfe will feel "pure, unadulterated hate" towards his girlfriend Maya Stepney.
The 'Emmerdale' actor has opened up about the soap's grooming storyline, which has seen Maya (Louisa Clein) exposed after her actions towards his son Jacob (Joe-Warren Plant), and scenes next week will see David have her arrested.
Opening up on his character's mindset, the 39-year-old star said: "David absolutely believes he has done the right thing. Now that he knows the truth, he absolutely despises Maya.
"There's no emotion over losing his girlfriend. That completely goes out of the window and it's now pure, unadulterated hate."
However, David's intervention doesn't go down well with teenager Jacob, who believes he and Maya are in love and thinks his dad has betrayed him.
The youngster doesn't accept that he was groomed and manipulated in the disturbed relationship, and it means there is much more to come from the hard-hitting plot.
Upcoming scenes will lead to Jacob turning on his own dad for the role he played in the breakdown of the relationship, and it remains to be seen whether the pair will ever be able to get back on track after the ordeal.
Matthew said: "Jacob actually witnesses Maya being handcuffed and put into the police car. He's obviously devastated and thinks that David has completely ruined his life.
"He still wants to be with Maya and thinks they're in love."
Jacob was unsure recently about whether he should simply leave his family behind and run away with Maya.
The pair are currently on the run, but next week, David is able to track them down which leads to the arrest, and it's clear things will never be the same.
