Love-related complications brewing under the surface will be out in the open in “Poldark” season 3 episode 8. A preview of next episode reveals the plot focusing on the election to parliament and the personal challenges of Ross (Aidan Turner) and Demelza (Eleanor Tomlinson). The following article contains spoilers based on the trailer.

Hugh Armitage (Josh Whitehouse), who has been hinting at his love for Demelza, will finally declare his feelings in the next episode. A preview video of next episode posted on YouTube shows the young man sharing his dilemma about loving the wife of the man who saved his life. The only problem is that Ross is close by, and he is not happy about the young man’s affection towards his wife.

In the previous episode, Demelza and Ross got into a big argument about whether or not he should run for parliament. The miner’s wife was concerned about George Warleggan (Jack Farthing) gaining more power, which will have a consequence on her family and the town. Ross, on the other hand, was not interested in being another man’s puppet, so he asked his wife to look for a “pet” elsewhere.

Demelza doesn’t have to look far because Hugh has been pining for her, and she can see it. But when Ross finds out about Armitage’s love for his wife, it will be a challenge to put a stop to it. The miner still loves Elizabeth (Heida Reed) after everything he has been through, and he confesses this to his wife.

Ross also provokes George by saying that the latter’s son is a Poldark. Although this could be interpreted as the boy getting his Poldark roots from his mother, Aunt Agatha (Caroline Blakiston) has already revealed the truth of the matter to George.

Meanwhile, the other big storyline in the episode is Ross considering running for parliament against George. Morwenna’s (Ellise Chappell) sister is in trouble because Reverend Osborne Whitworth (Christian Brassington) has his eye on her.
