The only reason why Roy is still not dead from violating the soul contract is because of the rare powerful magic tools that negate the backlash. However, it didn't mean Roy could just give more information to Crown Prince Arnet and betray the Heart Kingdom.
Every time he divulges crucial information about the Heart Kingdom and betrays the Heart Kingdom, he will receive a backlash. Moreover, the backlash would be minimal and weaker if he didn't go directly against the Royal family or share anything about their information.
This is also one of the loopholes of the soul-bound contract. Therefore, as long as it is not about the Royal Family's information, he could still withstand the backlash.
In other words, he could divulge information about others besides the Royal Family with minimal backlash. In the meantime, the bound blonde woman stays silent while looking at the floor after hearing Crown Prince Arnet's question.
