Matt Letscher is coming to Brothers & Sisters.

What will the presence of his character mean for Kitty and her marriage?

While Brothers & Sisters executive producer Monica Breen would not spill all the beans to Entertainment Weekly, she did concede that Letscher's charming widower will become a "serious complication" for the new parents.

"He comes to represent what she doesn't have with Robert," Breen told Michael Ausiello. "It leads Kitty to think about the status of her marriage and what she wants from her marriage."
