Julian Jerome is the son of notorious crime boss Victor Jerome. He wanted to take his father's place but his sister Olivia wanted to take over the family business instead. She conspired to kill Julian, but he was on to her and worked with Victor to fake his death. Victor died soon after and Julian used Olivia's obsession with Duke Lavery, a member of the family's organization, to set her up for Duke's murder. When Olivia figured it out, Julian killed her.

After Olivia's death, Julian became concerned with Jonathon Paget, who claimed to be Duke Lavery. Jonathon and Julian fought and were both presumed deceased. After, his lover Cheryl Stansbury was found to be pregnant with his son, who was adopted and raised by Tony Jones and Bobbie Spencer.

The Jerome family was not heard of for several years. Julian's sister Ava and her daughter Kiki came to Port Charles to get their share of ELQ. Julian arrived shortly after using the alias Derek Wells. He and Ava planned to take over Sonny Corinthos' territory, which used to belong to the Jerome family. Ava used an online gambling ring to connect Sonny's son Morgan Corinthos with her daughter while Julian went after Sonny's girlfriend, Connie Falconeri, by taking over Crimson.
