I think she has a lot of traits that fit, but equally one of the difficulties with traits is the overlap (I work with a cohort of service users with high levels of ND, PD, trauma and MH issues all overlapping usually combined with substance abuse, difficult to unpick many things)
But she is fixated on surgery, self absorbed, lacking in empathy, seemingly unable to connect, she has always spoken somewhat oddly, finds it difficult to learn new behaviours, repeats mistakes/problematic behaviours, often very flat.
All those traits could be due to ND, they could also be due to other issues. Her wildly fluctuating twists and turns and also lies, attachment difficulties, violence, instability etc can also be EUPD (if one accepts those criteria).
