Ross Poldark (played by Aidan Turner) and Dwight Enys (Luke Norris) have had each other’s backs throughout Poldark ever since they met on the BBC period drama.
Ross stood by Dwight through his relationship troubles with Caroline Enys (Gabriella Wilde), and the doctor helped the ex-soldier through his own marriage troubles and lingering feelings for ex Elizabeth Warleggan (Heida Reed).
As the series went on, Ross and Dwight became firm friends and their wives Demelza (Eleanor Tomlinson) and Caroline got closer too.
Yet for the first time the two men won’t be seeing eye-to-eye in the series, and it could escalate as Ross continues to delve deeper into politics and his work.
Speaking at a recent Q&A with Express.co.uk and other media, actor Luke revealed the scenes between him and star Aidan were “fun” to play.
He explained: “There is a bit of animosity between Dwight and Ross this year which is fun because they’ve never really had any over the last four series.
“So yeah it’s a bit of a head to head this year.”
The star then went on to describe the rift as an “edge” between Dwight and Ross, and it remains to be seen whether the pair can resolve their issues before the finale airs.
“There’s a bit of edge yeah,” Luke said. “Bit of edge between the two of them for the first time.”
Caroline and Dwight also went through some tragedy and heartbreak last season when they lost their new baby Sarah.

Asked whether the couple’s life will be plain sailing this season, Luke wasn’t pulling any punches.
“I think brilliantly it’s a slow road back,” Luke considered. “Because of course it would be.
“So yeah by the end of the series there’s some sense we’re gonna be able to put it behind us – but it’s a slow road back.”
What’s more, Dwight will get involved with George Warleggan’s (Jack Farthing) mental health problems this year with him finding renewed purpose in his work to help the grieving widow.
“After his struggles with France last year and other things, Dwight goes into the Royal College of Surgeons and talks about mental health,” Luke said.
“This time, and even now really, it’s quite a difficult subject.
“[The show] explores a lot of that this year… through this guy [George],” the star added.
George will undergo some tough challenges and tribulations before he can come out the other side.
Executive producer and writer Debbie Horsfield shed light on what’s to come for the semi-reformed villain, and revealed the show will be exploring the horrific experiences of mental health patients in notorious hospital Bedlam and the trials they were to forced to undertake.
Poldark continues tonight at 9pm on BBC One.
