Editing decisions made during the passage (Pathfinder: Kingmaker)

I know I can edit saves (because I've edited them several times), but this time I'm interested in one particular solution related to Jaital and her quest:
Spoiler When passing forced her to kill her daughter, but at the end of the game this decision came to an unexpected way, and she was killed by Tristian. I want to change this point, hence the question: which line of code is responsible for Jatal's personal quest?
