Awesome James! That is great she became a nurse! I worked at a hospital, and got to know the nurses there, they work like a team, accept each other like family, maybe she is seeing that not EVERY one out there is evil. Maybe, just maybe they are helping her see the value of family?
If she had a great time with you, and you didn't talk "religion"... then she goes to the convention, she just might resent the shunning talk.
After having a "Bethelite" husband who was a 'jerk', she may just be realizing that there are better people out there (like you, the father) than she can find in the org.... She may even be realizing that you just may have had a good reason for leaving, and admiring your for taking a stand! Right?
