Brothers & Sisters has tapped the sublime Amy Aquino — she was Dr. Coburn on ER and Keri Russell’s no-nonsense, chain-smoking shrink on Felicity (loved her!) — for a multi-episode arc, sources confirm to me exclusively. Additionally, Peter Gerety (Homicide, The Wire) is joining the cast for several episodes.
Aquino will play a doctor (spoiler alert!) treating a member of the Walker clan who shall remain nameless. Gerety, meanwhile, will appear as a “surprising outsider,” according to (ironically enough) an insider.
