Marietta found herself amused at Cho's berating of the Ministry. She couldn't agree more that they are totally incompetent, but she wasn't about to tell her that. She had to suppress a smile when Cho was talking about Marietta having a target. She was certain that she wouldn't have any problem with Death Eaters killing her.
Her bemusement was short lived, however, because as soon as Cho mentioned her mother her hackles were raised. She tried her best to keep the poison from her voice, but she could sense a hint of it rising. "I thank you for your input, Cho, but I think I know what's best for my mother. What kind of professional do you even mean?"
