Early in the game, you should get a scene in the kitchen with Jazz sleeping. Afterwards, there will be a scene with Jazz in the bedroom where she talks about her fear of failing.I got her spirit over 80, 250 points, and got to a point in the therapy where the two of them are praying in church.
After that, when you go for therapy again, the maximum limit is the praying at the church, no more new therapy scenes.
I talked to Hank already, talking about Jazz...
but in the end nothing happens, I keep getting the ending where she can't take it anymore and becomes a nympho again!
Once you've seen both of those, go to the office at 8am each morning, and assuming you've talked to Hank, you should get a scene where Hank will offer to help prepare Jazz for the trial, and you'll have a scene with Jazz and Hank in his office. This is the scene that counts towards "Hank's advice"
