Dillon returned to Port Charles in June of 2015, after years in LA and abroad, to try and stop his mother Tracy from marrying Luke. Though Tracy is no longer in town, there are other Quartermaines that could pull him home, such as his brother Ned.
Aspiring Filmmaker and Photographer
Dillon left Port Charles in 2017 for opportunities in the film industry. A number of film projects could easily draw him back to Port Charles. He was also a photographer at Crimson, so Nina could ask him to return for a project.
Dillon had been estranged from his father Paul Hornsby for many years. When Paul returned to Port Charles, he and Dillon began to rebuild a relationship. Dillon was stunned when the truth about his father being the General Hospital serial killer came to light. Perhaps a documentary on Paul could pull him home? Or he could come to Port Charles as part of the documentary Franco mentioned being filmed about the anniversary of his art show.
The Nurses Ball
Dillon was employed to photograph The Nurses Ball one year. He and Kiki also performed in the ball together. He could return to Port Charles to film the ball and do a documentary on it.
Dillon and Maxie’s Friendship
Dillon called on his friend Maxie to appear in a short film he was producing. Maxie’s sister Georgie was one of the major loves of Dillon’s life, and he has a good friendship with Maxie. When the truth about Peter eventually comes out, Dillon could return to be there for his friend. Or perhaps Maxie, now at Deception, could offer Dillon a job filming a commercial.
Dillon and Ned
With Ned learning someone is buying up ELQ shares, this could pave the way for Dillon’s return. Though he’s never had much interest in the family company, the Quartermaines rally when they are in trouble.
Dillon and Kiki
Though their romance ended off-screen after Dillon moved away, Kiki was an important part of Dillon’s life. A documentary on Ryan Chamberlain was began, but never finished. Maybe Dillon will take it over and it will bring him home to Port Charles.
Dillon and Lulu
Dillon also shares a romantic past with Lulu, and a complicated one at that seeing they were step-siblings. Dillon could return knowing a dark secret about Dustin, who seems too good to be true and warn Lulu.
The Quartermaine Family
Family is important to the Quartermaines, and any holiday celebration could be used to lure Dillon home. A Fourth of July party, a summer bash, or even the doomed Quartermaine Thanksgiving.
