The Russian man was in the doctor's clinic room with Anna while the doctor was giving her a checkup, there for moral support. I think Anna may have been autistic, because she never met anyone's eyes, but not in a prisoner sort of way. She seemed happy, and seemed to enjoy her work. In fact, she was bored with the easiness of the work and was asking for more challenging tasks. She was specifically working with another child, a boy, and saying "These are too easy. Give me a hard one." Which he obliged. Both Anna and the boy were around 10 or 11 or so.
