PRIVATE PRACTICE - "Who We Are" - In the first hour or a special two-hour edition of ABC's "Private Practice," THURSDAY, NOVEMBER 17 (9:00-11:00 p.m., ET) -- entitled "Who We Are" -- the Seaside Wellness group stages an intervention for a defensive and volatile Amelia, who has resurfaced after disappearing on a 12-day drug binge with her boyfriend, Ryan. During the intervention, Amelia mercilessly attacks her friends one-by-one, and Addison, in particular, has trouble seeing her sister-in-law in her present condition.
