RWTF, Jack actually went back into the military after the war and served in Special Forces (before JFK gave them their green berets). Margot committed suicide. As a young actress, her sister Mariel made a movie called "Personal Best" (in which you get to see a LOT of Mariel!), playing the role of a female track athlete preparing for the 1980 Olympics (when Carter kept our team home). Initially, she's a lesbian in that movie, but gets "converted" from the Dark Side by a fellow Olympian, a swimmer--played by Kenny Moore, who was a REAL Olympian, but as a marathoner and not a swimmer.
