The long-running (and mostly off-screen) feud between the two comes to a head in season 4. Here’s what we know about the feud between Natalie Berzatto and Francie Fak.

There’s the Berzattos, the Fak brothers, Uncle Jimmy, Uncle Lee (Donna’s on-and-off boyfriend), Cousins Michelle and Steve, friends Richie and Tiffany, and Natalie’s husband Pete—a mixed-company cocktail waiting to be turned into a Molotov.

Another season of The Bear means another fresh batch of celebrity guest stars. And as locked-in fans of Christopher Storer’s hit FX series likely predicted, it also means it’s time to unveil a new Fak family member!
