Warning: This article contains SPOILERS for FBI Season 7, Episode 17, “Lineage.”
The latest episode of FBI has left viewers with a tantalizing hint regarding Jubal (Jeremy Sisto). However, the series’ complex dynamics suggest that immediate resolutions are unlikely. It’s a hallmark of Dick Wolf’s productions to frequently alter their casts, especially given the lengthy runs of the shows. Since FBI debuted, the ensemble has undergone several changes, with three different leaders introduced in just the first two seasons.
With recent cancellations from CBS and the announcement of a forthcoming spinoff, there’s a possibility that significant changes will be felt throughout the franchise when FBI launches its eighth season. Considering that the new spinoff will feature elements related to the CIA, Jubal’s role overseeing the fusion center might gain considerable importance moving forward. However, this assumes he retains his current position following the developments in the latest episode, “Lineage.”
Isobel Evaluates Her Future in FBI Season 7, Episode 17
An Optimal Moment for Retirement?

At the start of the episode, Isobel (Alana de la Garza) reveals to her husband Phillip (Tom Cavanagh, known for The Flash) that she has reached the milestone of 20 years with the bureau, qualifying her for retirement and full benefits. Despite this, Isobel appears hesitant to leave her leadership position, seeking insights from Phillip on his own retirement timing. He advises that while the work is relentless, the decision to leave is ultimately about personal readiness.
Although Isobel initially seems inclined to heed his advice, her focus shifts as the team pursues a case involving Frank Grippo, a gangster connected to her past investigations and responsible for serious offenses. While Frank’s arc concludes tragically, Isobel realizes there’s unfinished business, especially as Grippo’s daughter manipulates events to assert control over his criminal operations. Phillip supports her decision to continue confronting crime, but the option of retirement now lingers in her mind, complicating her future.
Potential Changes in Leadership: Jubal’s Prospects
Aiming Higher: Jubal’s Ambitions

In the meantime, Jubal appears to be managing well within the fusion office, yet it’s established that he has previously applied for Isobel’s role. Though he shows surprise at Isobel’s contemplations of retirement, her departure could catalyze Jubal’s long-desired promotion. Given the show’s history of cast changes, including Scola’s (John Boyd) new partner Dani (Emily Alabi), another shift in cast dynamics seems increasingly probable.
While it’s unlikely that Jubal will take over Isobel’s duties unless Alana de la Garza opts not to renew her contract, should such a scenario arise, the series would face challenges in identifying an appropriate successor to Jubal—a significant task given the narrative’s trajectory. Despite CBS canceling the backdoor pilot for FBI: CIA, the new spinoff will likely establish connections with the fusion center early on. This development might hint at a cameo from Sisto, but if Jubal ascends, it will create new opportunities to see who steps into his impactful role.
