What words or phrases does this character commonly use?
She doesn't have a catch phrase as such but she is educated so it seems fair to state that she will be at least fairly eloquent and literal. Her description of Hassan as "your idiot child" stands out the most from her limited quotes.
What language techniques does this character commonly use?
Her language seems to be rather vulgar due to the situation she was put in, however she has to be regarded as intelligent due to her origins. Due to the apathy and ego-centrism she has presented her character voice is likely to be self-focused as well as she is likely to use retrospections into the past to present herself in a different light. She is unapologetic and lacks insight into herself and her own actions so she would not consider herself to be a bad person and would not justify her own choices considering them to be always right.
