Growing up, Jodie O’Brian’s father was a pro bowler, and she followed in his footsteps, bowling well enough through high school and college to receive a college scholarship for bowling. This skill also aided her in getting her first undercover assignment with the IRS, investigating Sonny Veranda under the guise of being the resident pro bowler at his bowling alley, The Splits under the name of "Jonie O'Brien". She was around 26/27 years old at this time.
After the arrest of Sonny, Jodie’s father was murdered by the Whitaker family in retribution for her meddling in their affairs, and she was blackmailed into working for them as a hitman in addition to continuing to work for the IRS.
Although she and Sonny occasionally cross paths in their new lines of work, their relationship is much colder than it previously had been when they worked together at the bowling alley.
