I actually think Daniel will find out first because Jack is so not in the key storylines for now that I can't imagine how he will find out first. I fear for Daniel
I think since Victoria has cashed out her shares so Daniel and Charlotte willbe comfortable, though Daniel won't have Grayson Global to inherit but Victoria probably knows Daniel isn't keen in the business anyway.
I do think Conrad and Victoria won't ever be civil again. Conrad obviously has father issues but Edward Grayson favoring Victoria over his own son makes no sense to me.
