In the movie,the line where Evelyn tells Gittes about her father is more mysterious than the line in this draft.

Only two words are used.

My father and I ... Understand?

Then Gittes asks her if he raped her and she responds negatively.

This is teaches us about the power of mystery and subtext.

Don't you agree Mr Scott?

I think it shows that any topic can be done without too much consternation.
