Move to Cornwall
Morwenna was unhappy with the match, because she did not love her potential suitor. She met with Drake, and they kissed but she failed to tell him of what George wanted.
Geoffrey charles and Morwenna have been entertained by watching the toads that Drake Carne has put in George Warleggan pond annoy him. As to Drakes surprise Ross Poldark had already played a toad trick on him at school as George would not accept that his grandfather was a blacksmith and unstinting he wanted nothing to do with the man which Ross and Francis Poldark found absurd. But the drastic consequences is that George and Elizabeth find out Drake put them in the pond and that he and Morwenna are in love.
Just when Morwenna thinks she can marry Drake George puts him on trial as a capital offence 'stealing' a Bible which Geoffrey charles offered as a gift. Morwenna was forced to marry Mr. Whitworth as George threatened her by saying if u don't marry him then Drake will hang. It ends with Drake, Demelza Poldark and Ross Poldark running to church to stop it but they are already married.
Morwenna has a marriage which she hates. Osborne is a horrible man whom she refers to Demelza Poldark as a monster. She ends up pregnant with osbornes son but during her pregnancy ossie as she refers to him still sleeps with her. When Dwight Enys comes to check on Morwenna he says she is gravely ill and that ossie should not sleep with her. Still refusing morwenna ends up more ill than she was and on the brink of death.
When Rowella Chynoweth turns up she helps Morwenna out with Ossies daughters. As he can not sleep with Morwenna, Ossie sleeps with rowella. During their sons birth Ossie prays that Morwenna will die as she is not committed to a full martial life. Enys returns after a while and says Morwenna is getting better.
Osbornes still sleeps with Rowella and is getting Morwenna pills to sleep a lot. When a librarian calls to ask Rowellas hand in marriage she is thrilled but only because it will cover up the fact she is pregnant with Osbornes child. The librarian asks for a £1000 to keep his mouth shut and to raise the child as his own, Osbornes refuses. Rowella threatens him with a letter to give them £500 or the letter will be sent to the Bishop revealing everything.
Osbornes agrees but Morwenna finds out everything. While she is in her room with her son, osborne comes in and asks to sleep with her she says no which angers him. Then Morwenna threatens him if he tires she will kill their son which Osborne is shocked by. Then as he leaves Morwenna picks up her son and says u know I never meant revealing she in fact loves her son very much and only said it to protect her and her son.
At the end of the finale we see Drake Carne leave a bunch of flowers at Morwennas door and she picks them up. Drake is hiding out with the gates but Morwenna knows he is around. She replys 'wherever you are know I love you'. Drake knows she said this and feels warmed.
