Hello. You did not say what text you are referring to, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
A clue that a character has changed his mind occurs when he begins to abandon positions he had previously established. In addition, this character can begin to support something that he did not support, or to adopt behaviors that he criticized, but that saw that they are not wrong or harmful.
I agree strongly because it makes so mych sense
