'Private Practice': Caterina Scorsone Teases 'Powerful' 'Intervention' Episode (Exclusive Video)

Private Practice's Amelia (Caterina Scorsone) is spiraling out of control.

On Thursday's two-hour "Intervention" episode, the doctors of Seaside Wellness -- led by her former sister-in-law Addison (Kate Walsh) -- will confront their colleague and friend.

In a clip exclusive to The Hollywood Reporter, Scorsone teases the "important and powerful episode" that features Amelia arriving at the practice after disappearing on a 12-day drug binge only to find her fellow doctors have canceled all the appointments for the day and brought in a counselor.

"One of you has to have the balls to say something to me," a none-too-pleased Amelia challenges her colleagues. "Do you? Any of you?"

The Private Practice "Intervention" episode airs Thursday from 9-11 p.m. on ABC. Watch the clip and come back Thursday for more from Scorsone.
