As revealed in the FBI Season 3 episode, "Unreasonable Doubt", when his girlfriend at the time, Rina Trenholm told him she didn't want to be his mistress with Jubal also reluctant to tell his wife about her, the two broke up.
Due to the fact no hit and runs had been reported, he came to suspect that it had been an animal and this incident was what prompted him to begin AA meetings and presumably get sober.
Jubal remained sober for nearly ten years up until the FBI Season 5 episode, "Breakdown" where following a medical crisis concerning his son, Tyler, he temporarily relapsed, drinking once again although he later stopped and was seen going to an A.A. meeting.
In the aftermath of 9/11 in 2001, Jubal, already an agent with the FBI was assigned to a multi-agency task force that saw him working alongside the NYPD which was revealed in the Season 5 episode, "Sins of the Past".
In addition, he's also a highly skilled crisis negotiator which is seen in "Safe Room", "Fathers and Sons", "Grief" and "Hero's Journey".
When Jubal and Trenholm reunited in Spring 2021 during a case concerning drug cartel boss Antonio Vargas, they secretly began a relationship once the case had ended with the relationship continuing up until her death in January 2022 with it being revealed that Vargas had arranged for Trenholm's death in revenge for the murders of his own wife and young son who were killed and hung on a bridge in Mexico.

In the FBI Season 3 premiere episode, "Never Trust a Stranger", a conversation between Jubal and Castille reveals that Jubal received a text from Kristen, informing him she had moved to Dallas, Texas and subsequently joined the FBI field office there with former NYPD officer Tiffany Wallace later permanently replacing Kristen as Scola's partner.
Previously an Assistant Special Agent in Charge and a Supervisor of the Fugitive Squad, she also attended and graduated from West Point while even working a brief stint in Silicon Valley.
In 2012, assigned to the Alabama field office, she was one of the first responders at the white supremacist bombing of a church that saw many fatalities including three children, something that still haunts her as revealed in the Season 2 episode, "Hard Decisions".
She was also possibly in the Drugs Division and good friends with Special Agent Kyle Miller who was murdered at the hands of Antonio Vargas, the head of the Durango cartel in 2013.
A native of New York City and graduate of Princeton University, Scola is the middle of three children and has an older brother, Douglas, and a younger sister, Alexander.
