Other Characters Coming

Debbie Horsfield Talks Poldark Season 3

Debbie Horsfield, Poldark scriptwriter, has said in an interview, "We're thrilled to be kicking off series three with a fantastic array of new characters and a story which scale new heights of conflict, feuding, passion and drama."

Elizabeth is Pregnant

Ross is going to be much older but not necessarily wiser and his recklessness will sometimes cost him and his loved ones. We're going to be in for a rollercoaster ride where the stakes have never been higher than before. The end of Poldark season 2 have left many unanswered questions as newly-married Elizabeth is pregnant without knowing who the father is.

Other Big Revelations Coming

Meanwhile, George Warleggan (Jack Farthing), who narrowly avoided a mob lynching, is planning to send Elizabeth's youngest son from her marriage to Francis (Kyle Soller) away to boarding school. The fate of Aunt Agatha (Caroline Blakiston), who suspects Elizabeth's unborn child belong to Ross, is still not known. Poldark Season 3 will be epic.
