Hello. You have not shown the dialogue to which this question refers, which makes it impossible for it to be answered accurately. However, I will try to help you in the best possible way.
Rebecca is a character who has a certain authority in the city, it is likely that the dialogue to which the question refers exposes that authority, showing how Rebecca's words have a strong value and claim respect for the figure she represents. This can complicate her situation amid accusations of witchcraft, because the respect she imposes can be seen as a form of alienation and an attempt to control the minds of others, reinforcing the idea of witchcraft.
