Maria (SPOILERS!)
When the Dr. Polda's daughter, Maria is reunited with her father, he quickly sees that she is a fake. Was that the Anne Dawson character, returning from the earlier scene in Switzerland? I didn't catch any reference to whom she was, as in a name, in the Maria scene. And there isn't any other women in the cast that aren't accounted for. And, I'm assuming that she was not finished after her scenes in the earlier part of the film.
Did I miss something? or was that Anne Dawson reappearing when we were all expecting it to be Maria??
