Alex Poletov Baldwin

Alex Poletov Baldwin arrives as a child bridging two worlds and two rival space programs, born into the extended Baldwin family with a name that carries a Russian father's mark. He is watchful and quiet at first, a kid who doesn't quite know which language or which flag is fully his, growing up in the shadow of astronauts.

The show has always used its children to carry the weight of history the adults are too busy making to notice, and Alex is built for that job: a living symbol of détente and its costs. Sean Kaufman plays him without precocity, letting small hesitations do the work of a kid caught between countries.
