"What do you want to do now?" Dr. Guan continued to ask, "Do you think she would want to do something to that patient? Perhaps you should tell Doctor Du to be on guard? Although she is annoying, I think doing something like this would be harmful to her, without any benefit and no motivation. Does she have a personal grudge against that patient?"
If Doctor Hu had murderous thoughts because of the exam-swapping incident involving her mother years ago, that would definitely be impossible. Even if there were some shady dealings back then, the exam was based on recommendations, so exposing anything wouldn't have helped. Aunt Min had already said that pursuing things now was meaningless.
Just as Dr. Guan analyzed, Doctor Hu had no motive to commit the crime. Xie Wanying had considered all of this calmly, which is why these questions must be asked directly to Aunt Min.
