Isobelcastille Stories

Isobel Castille, She's the special agent in charge in the FBI, she loves her job and takes her job very seriously. Isobel has always kept her family and personal life very private as that what she feels is necessary in order to keep them safe. But when Isobel gets a frantic call from someone she loves, she is willing to do absolutely anything to keep that person safe. Inside look into Isobel's life as someone who works for the FBI and as a parent.

Because my friend @GogoD4 ask it... Here an other about Isobel and Jubal. An OS where Jubal finds Isobel on the rooftop crying over Jess death plus her father case and he try to comfort her. The characters are not mine but the story is.

A FBI fanfiction

Maggie gets trapped in the lab when the sarin gas canister gets dropped onto the floor and opened. Will she get saved in time?

After an undercover mission, Isobel is reunited with her family.

When Isobel jokes about how "normal couples" host dinner parties instead of interrogating suspects, Rina takes it as a challenge - and suddenly their apartment is full of food, friends, and laughter. As the night unfolds in a swirl of garlic, wine, and inside jokes, the women find themselves accidentally on display: the quiet touches, the shared glances, the rhythm they've built without realizing. In the mess of burnt dessert, borrowed wine glasses, and soft chaos, they see it clearly - they're not just together, they're home. And for the first time, it doesn't feel scary to admit it.

Isobel Castille is known for her composure. Her crisp suits, sharp lines, and sharper decisions. She doesn't raise her voice, doesn't crack under pressure, and definitely doesn't curse. At least-that's what everyone thinks. Behind the closed doors of the JOC, when the paperwork piles too high and the politics get too stupid, Isobel starts to lose her grip on professionalism... and gain something much more satisfying: the cathartic joy of finally saying what she really thinks. Each one-shot in this series follows one very bad day, one ridiculous inter-agency call, or one "Are you f**king kidding me?" moment-where Isobel trades diplomacy for directness, and finds unexpected support in the agents who'd go to hell and back for her. She doesn't fall apart. She just stops pretending she's not already carrying everything.

It was supposed to be a simple extraction. But the line between "routine" and "disaster" is always razor-thin in the field. For Jenzii 🤭

A joint operation brings Jess Blake and her team to New York, chasing a lead on a domestic terror cell that's one step ahead of both agencies. When a sting goes violently wrong, Jess makes a split-second call that saves lives-but costs her own. As Maggie Bell grapples with the fallout and a mountain of unanswered questions, the team uncovers that the mission was never as straightforward as it seemed. Jess's death wasn't just tragic-it was targeted. Maggie, OA, and the Fugitive Task Force are left to finish what Jess started, carrying the weight of her loss as they fight to expose a truth someone is desperate to keep buried. A canon-compliant crossover that explores duty, sacrifice, and the people we become after everything breaks.

Jess Lacroix died in the line of duty, who to replace him? The team is united and does not wish anyone at his head. Isobel heard their wishes, and also fulfilled a wish of his late friend in relation to this team he cherished so much.

After an argument with the team, Isobel disappears without a trace. The team does not worry more than that at the beginning, thinking that she does not assume what was said and done. But this is not the case, and the team will realize their mistake. Will it be too late? Too late for Isobel?

Based on Season 5 episode 20. Focused on Maggie, obviously.

This one shot is based on the events of the FBI Season 7 finale, "A New Day," where Isobel collapses after a high-stress operation, leaving her fate uncertain.

When SAC Isobel Castille is summoned to a closed-door meeting with the ASAC, ADIC and DIC of the New York Field Office, she assumes it's just another political dance with brass and egos. Until the first shot is fired. The conference room becomes a war zone. The building goes into lockdown. And Isobel becomes a hostage in a strategic coup orchestrated by someone on the inside-someone with a grudge and a plan. Back in the JOC, the team realizes the severity of the situation before anyone else does. With the upper echelons in chaos, it's up to Jubal Valentine and the field agents to coordinate a rescue mission without command authority, without a clear threat profile-and without time. They've stopped bombers, serial killers, and terrorists. But now, their boss is the target. And this time, it's personal.

A new case lands on the Joint Operations Command's desk-seemingly routine, until links begin to surface connecting it to a long-closed investigation from nearly a decade ago. As Isobel leads the team through a maze of intel, one name keeps resurfacing: Dana Mosier. Her former mentor. The previous SAC of the New York field office. A woman Isobel thought she knew completely. With pressures mounting and questions circling around Dana's past decisions, Isobel is forced to confront the possibility that the people she admired most may have buried dangerous truths. As loyalties are tested and reputations hang in the balance, the line between justice and personal history begins to blur. The JOC must tread carefully. In the FBI, ghosts don't stay buried-they wait to be found.

Between the chaos of cases and the weight of the badge, Maggie and Isobel find a quiet moment to just be.

Isobel never made it to work. She didn't call in. She didn't answer her phone. She didn't show up. And by the time they find her, it's far too late. The worst part? She wasn't armed. She was at home.

Isobel's command of English is flawless-until it isn't. A botched idiom in the bullpen spirals into a running joke, much to Jubal's amusement. Between "shit ducks" and cats coming out of hats, she's had enough of English metaphors-and she's not afraid to complain in Spanish about it. Just another day at the office for the FBI's most linguistically creative SAC.
