what questions remain unanswared at the end of act two?

I'm not sure about questions but Kate still doesn't know her son is engaged to Ann, and she still hasn't been told that her son Larry is dead. In fact...... they even show her a horoascope that points to the possiblity he may still be alive.

There are a few questions that remain unsolved at the end of act 2 -

1. What will Chris do, what will be his next step?

2. Will Ann and Chris get married.

3. Will the case be re-opened?
