From Halopedia, the Halo wiki
In August of 2530, when Rion's mother refused to take Rion to meet her father, John Forge, Jillian offered to take her instead. Soon after arriving at a lounge in Chicago, Jillian was approached by a drunk Lieutenant Prosser, who made rude comments towards Jillian and Rion. Jillian struck Prosser but he shoved her against the wall, with his forearm on her throat, pressing hard. It was at this time John Forge arrived and stopped Prosser, engaging him in a fist fight, which required three MP's to haul Forge off of the Lieutenant. Lieutenant Prosser later attempted to file assault charges against Forge. John was incarcerated for striking a superior officer, but all charges against him were dropped after Rion testified that he had saved her life, while Prosser eventually faced a court-martial. John Forge was later reassigned to the UNSC Spirit of Fire personally by Admiral Preston J. Cole. A few years prior to John's father's death, Jillian left Chicago to take a job at a corporate law firm in Sydney, Australia. There, she eventually died.
