Her parents may not even notice a change w/her. Don't forget, they like to play actors and actresses. Your wife may not appear "off kilter" w/her parents.
I doubt that they will say anything to her about what she's thinking and/or doing. Generally, when someone steps in and offers advice to the MLCer about what they are doing, it makes them just a tad worse or the MLCer will not associate w/them again. No matter what is said to them, they are going to do what they have to do in order to get to the other side. They are that bound and determined to prove everyone wrong and that they are right.
Buckle your seat belt and pray that she behaves herself while visiting her parents.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
