Despite this, Karen returned an affection for him and continued to pursue him. They would eventually slept together, but Mark Daniel found out. Karen was later found dead, when Mark ended up killing Karen in revenge and fleeing the country. Dwight was devastated by her death.
Helping the Poldark Family
When Elizabeth Poldark and her child, Geoffrey Charles Poldark became unwell, Dwight helped Demelza Poldark tend to them and they recovered from their throat infection.
However, he was later called by Ross to tend to Demelza and her infant daughter, Julia Poldark who were now unwell with the same throat infection. Dwight stayed with them and tried to save them, but later had to tell Ross that while Demelza would recover, Julia would eventually pass away. He stayed with Ross and Julia until she died, and Demelza eventually recovered.
Marriage to Caroline Penvenen

He met Caroline Penvenen, a wealthy heiress and in time the two fell in love. They had hoped to marry, but her uncle, Ray, would not give his approval of the match.
Dwight and Caroline had planned to elope together, but when Dwight never showed up to meet her because he became involved in smuggling scheme of Ross, he eventually left her. When he returned, he found her engaged to another. Despite this, Caroline and Dwight would eventually marry.
On the night of their wedding, Dwight was called away to assist in the birth of Valentine Warleggan. He didn't arrive home until late, and then made the decision to rejoin to the Royal Navy where he was taken prisoner in France. Ross Poldark helped to break him out of jail. Once he returned home to Caroline he was severly traumatised by the events of the war and distanced himself from Caroline. With the help of Hugh Armitage, he became his normal self.
