The Children of Yuri and Tonya

Tonya and her family escaped to Paris. After that....?

"You gave me loaded dice?!?"

So many people are asking, "What happened to this person or that person?", as if the script was full of holes. Robert Bolt was a superb writer, so if he left holes, it was intentional. The very first scene (taking place, chronologically, at the end of the story) sets the stage - Zhivago's brother is in search of Zhivago and Lara's daughter. The story is about a period in time and a place where dislocation was the norm. I believe we were meant to feel this lack of closure, because that is what life was like then. We know what happened to Zhivago (heart failure) and where he is buried, but Lara's fate remains a mystery, as does that of Komarovsky. What becomes of Lara's elder daughter is never made clear (when Lara returns from the far east to search for her younger daughter, is the older daughter with her?). Zhivago's wife and two children (and her father) are expelled, and that is the last we hear of them because that is the last that Zhivago ever hears of them. Presumably they did okay in Paris and were able to make a decent life for themselves there, particularly if her family (who were clearly quite wealthy before the Revolution) somehow had sources of cash abroad.
