Its' not known when she and Durwood met. At some point, after he left Dougal county, he met and eventually married Fiona. Though she believes he enjoys her family, he has been hinted to be offended by how they treat him. His biggest annoyance was her father's jokes and how her mother checks to see if he inked where he sat.
She does try to discipline and be active in her children's lives. Not when she's drinking, according to her husband. When they meet the Cuyler's, she's not very fond to meet them due to Early's groping and Granny's racial slurs to her and the kids.
Later when Durwood "leaves for work", Fiona immediately reveals to Rusty that she is aware of him losing his job two months ago. She soon gets drunk and begins to come on to Rusty this later turns to sex where clothes and ink are found all around the house leading to the bedroom where Durwood catches them in the act. Rusty confirms the affair as something amazing while Fiona kicks him off the bed and nonchalantly says "He raped me send him back."
Though, Durwood is still clearly upset from the affair, the two work together to knock Rusty out and send him back home. Durwood doesn't plan to let the affair go. After they knock him out, he angrily calls Fiona a "whore".
