What The Latest Casting Means For FBI Season 7

Isobel Revealed More About Her Life Recently

Why CBS Canceled FBI: International & Most Wanted But A CIA Spinoff Is Still Happening?

In a shocking turn of events, CBS has canceled FBI’s two spinoffs – FBI: Most Wanted and FBI: International. However, the franchise is far from over.

Isobel’s new husband has three daughters, which causes the Special Agent in Charge to marvel at her situation. It’s possible that after the revelation in the episode, Phillip will turn out to be a secret villain who purposefully targeted Isobel. That would be something of a trope inshows likeFBI. Alternatively, it could turn out that their relationship is solid and that Cavanagh will have a gradually more significant part in the story.

Our Take On The New FBI Casting

The Show Works Differently Than Some Network Dramas

Unlike other network dramas, such as9-1-1andGrey’s Anatomy, the focus of the CBS series is tilted to the case in any given week rather than the personal lives of the agents and their conflicts. This means that it’s not too surprising thatFBIhas been able to keep Isobel’s big wedding a secret. There may well be a reason for that, though, which will come up at some point this season.

FBI season 7 airs Tuesdays at 8 PM ET on CBS
