Yuck.
A question that shouldn't be answered without knowing her very, very well.
Maybe you can lead her to answer it herself, by giving her a hypothetical similar example and see what she answers.
It doesn't have the right answer (what we think hypothetically and how we really react don't always match), but it could be helpful.
I just found out her some has gone off to live in that Asian country. If he achieves literacty, he might tell her. His relationship with her is a bit contentious, I dont see him being delicate about how he tells here.
