Slight hint of diminished empathy. Not to the point of psychopathy/ASPD (so no disorders here, only symptoms), but she clearly needs to put a bit of a conscious effort to understand nonverbal cues, did not internally feel or mimic emotional expressions from her surroundings, and she did not passively feel what others feel—her perspective was centered entirely around herself. She also detaches with no problems and forms virtually no sentiment despite interacting with others in a socially acceptable manner. Typical signs of diminished empathy.
There was also hint of anhedonia, but it didn't seem particularly notable over the above, as she could still note when she had a good time.
