Isobelcastille Stories

Cassidy Lane learned early that trust is fragile. After losing her mother to cancer and watching her father rebuild a life that didn't include her, Cassidy grew up fast-relying on no one but herself. That mindset carried her all the way from the streets of New York to elite security work for the President, and later into the high-stakes world of S.W.A.T. in Los Angeles. But just when everything seems under control, her past catches up with her. A name. A secret. A brother she never knew existed. As buried truths begin to surface, Cassidy is forced to question everything she thought she knew about her family, her past, and even herself. Because some secrets don't stay hidden... They live between the lines. ©All characters from the television series FBI, FBI: International and S.WA.T are the property of their respective creators and do not belong to me.

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.

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 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'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.

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

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.

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

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

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?

After Rina's death, Isobel finally gets a chance to say everything she never could - and still finds herself being interrupted.
