Ding! Ding!

Round 97 of the ongoing Nora vs. Holly feud will commence this fall on Brothers & Sisters.

TV Guide Magazine reports that the mothers-in-law-to-be will throw an engagement party for their children, Justin and Rebecca, on the September season premiere.

As previously reported, Marion Ross will reprise her role as Nora's mom, Ida, for the occasion.

But that stress will be nothing for Nora, not compared to her disagreement with Holly over their kids’ impending nuptials, a fairy tale wedding that will likely highlight the return of family members Tommy, Julia and David, who returns to walk his daughter down the aisle.
