Who is She?

Mary said, "Actually, I don't want to talk about it at all. Hugh said he wanted me to provide him with some writing material and inspiration." 

Mary's meaning was very clear. She didn't want to. 

Moreover, Mary felt that her second brother, who always looked genial and funny, the star, Nelson, her idol, seemed to be constantly testing her. 

Nielsen continued to ask with a smile, "Then who are you? I definitely don't believe that you're just an ordinary girl! After all, no ordinary girl can kill an assassin with dual blades!" 

Mary really wanted to tell him that this was her first time using dual blades, although they were indeed quite handy when she used them. 

Mary smiled. "Nelson, everyone has their own secrets. Can you respect my privacy?" 

Nelson wanted to dig deeper, but Jayce patted him on the shoulder. "Alright, she doesn't want to talk about it. You won't get anything out of her."
