"...Where can you find a doctor as qualified as me to get a second opinion?"
Liza said to them with a very sour and hurtful voice, She was very wronged. What did she do to deserve this treatment from them? Is this a reward for saving someone's life? If not for her Gloria will be in big trouble as no one else in that hospital knows how to do that complicated surgery on the spot.
Though she is more interested in illnesses than patients, But she does follow her twisted ethics that put patients life first, and yet Grace who she thought is a good woman started to berate her.
How can anyone question her qualifications? She had taken almost impossible-to-treat patients and yet not a single patient of hers goes home with their illnesses, She has a perfect record.
Not even since she did not encounter any illness that she could not cure in the history of her long career, That's why she was especially offended by Grace's words doubting her qualification.
