"Previously on the West Wing" spoken by Leo Christmas draws near as an increasingly unstable Josh (Bradley Whitford) begins exhibiting bizarre behavior that has everyone concerned; behavior that finally crosses the line when he explodes at the President (Martin Sheen) in the Oval Office. Josh is ordered by Leo (John Spencer) to consult with a doctor who specializes in analyzing trauma victims named Stanley Keyworth (Adam Arkin). What's particularly telling is Josh's identification with a dead fighter pilot who recently took his own life by deliberately crashing his jet -- a man who coincidentally shared his birthday and experienced emotional trauma after being shot down over Bosnia.
