FBI returned to the airwaves for its second season, but it wasn't without some changes. Special Agent in Charge Dana Mosier, played by Sela Ward, submitted her resignation from the FBI at the end of Season 1, and Season 2 proved that it wasn't a fake out. Fortunately, her replacement was a familiar face: Alana de la Garza as Isobel Castille. While the actress debuted on FBI in Season 1 as part of the backdoor pilot for FBI: Most Wanted, she has since become a series regular on the parent series.
In the premiere, there was some serious tension between Alana de la Garza's Special Agent in Charge Isobel Castille and at least OA after she told some selective truths about the case involving Muslim terrorists. It was clear that Castille wasn't going to be pushed around or told what to do by the people beneath her in the FBI hierarchy; what wasn't 100% clear was if she would have the team's best interest at heart in the grand scheme of things.
Fortunately, FBI (and Chicago P.D.) showrunner Rick Eid spoke with CinemaBlend about Alana de la Garza's character, and he described her role in the team like this:
SAC Castille may not be warm and fuzzy to OA, Maggie, and the rest of the FBI team in New York City at all times, but she sounds like she could be what they need in that office. "Getting the job done" is obviously extremely important when it comes to the kinds of cases the team investigates, which already range from domestic terrorism to kidnapping in Season 2 alone. And, as Rick Eid stated, she has her team's back. What could be more important?
That doesn't necessarily mean that everybody will always get along, which wouldn't be realistic anyway. She has a larger job than everybody else on the team, and hopefully that means somebody who keeps her eye on the prize. She's responsible for the rest of them and can't just go rogue!
Interestingly, Dick Wolf suggested over the summer that a crossover between FBI and the Law & Order/Chicago universe shows could be possible, and Rick Eid shared with CinemaBlend his thoughts on how such a thing could go. That could present a complication regarding Alana de la Garza. She played Connie Rubirosa in 85 episodes of Law & Order, eight episodes of the short-lived Law & Order: LA, and one episode of Law & Order: SVU.
If the FBI universe is revealed to be the same as the Law & Order/Chicago universe, then Connie Rubirosa has a doppelganger in the form of Isobel Castille! Deadline reports that Alana de la Garza will recur on the FBI spinoff, FBI: Most Wanted, as a guest star once that show debuts next year, in addition to her work as a series regular on FBI.
To see more of Alana de la Garza as SAC Isobel Castille, tune in to new episodes of FBI on Tuesdays at 9 p.m. ET on CBS in the fall TV lineup.
