Private Practice – 9:00 PM ET, ABC

Who’s in charge here? You’ll be surprised at the outcome of an election to determine who runs the practice — and so will the candidates, Sam and Naomi (Taye Diggs, Audra McDonald). Addison (Kate Walsh) treats an Afghan girl who wants to keep her past a secret. Speaking of secrets, Cooper’s (Paul Adelstein) personal life catches up with him in the new episode “Past Tense.”
