Brothers & Sisters will introduce a pair of new characters next season.

The first will be a medical-school study partner for Justin. This individual will be a 16-year-old straight-A kid genius that will will challenge Justin’s confidence.

No actor has been cast in the role, but TV Guide Magazine reports that he may be of East Indian decent.

Meanwhile, information has been leaked about the character French actor Gilles Marini will portray.

When Sarah (Rachel Griffiths) returns this fall - after a much-needed vacation in France - Marini will appear as her new boyfriend. According to executive producer Monica Breen, Gilles’ character will “make Sarah really think about her views on men. He will be an amazing challenge for her.”

He'll also play a prominent role in Sarah’s business dealings at Ojai Foods.
