Demi is the step-mother of Marie Fielding's son Arlo Fielding and girlfriend of Chris, Arlo's father.
In 2023, with the help of Abe Fielding (Arlo's half-brother), Demi and his partner Chris took Arlo away from his mother where they have been in hiding in various places in the UK and Ireland for over a year.
In March 2024, Demi calls Abe, complaining that he cut all contact and then expects her to pick up the pieces and she needs to see him. Abe asks her to leave him alone. The following day, Demi turns up at The Cage, insisting that she came a long way. Abe gives her an envelope full of cash telling her to do as he says. A few weeks later, Abe video calls Demi, revealing that her and Chris have been hiding Arlo Fielding.
In May 2024, Demi returns to the village to take Arlo Fielding away on his thirteenth birthday to Paris. Arlo is hesitant to go so Demi tells him that Chris and her are his real family. She lies to Arlo that Marie Fielding's anger at Chris is all an act as it will ruin the birthday surprise. After Demi dragged Arlo to the car Abe Fielding arrives telling her that Marie has phoned the police. After Arlo is saved from the car, Demi drives away.
