Well, I did think she might meet her grandparents. But besides that, that Paige will try to give her a normal childhood, but that Olivia will still grow up with an abnormal family whether they tell her the truth or not. Once the internet comes along, she'll discover it anyway. She'll be curious and she's one generation removed from the emotional impact, so at some point she might want to go to Russia and learn about her roots and find her family. The smaller her father's family, the more she'll be inclined to start digging.

Also, about Duolingo... I started their Russian course, but after a while felt that despite doing well, I wasn't really learning the language. It was more a matter of learning patterns. So I dropped it.
