''
Histrionic personality disorder (
HPD) is defined by the American Psychiatric Association as a personality disorder characterized by a pattern of excessive attention-seeking behaviors, usually beginning in early adulthood, including inappropriate seduction and an excessive need for approval. ''
''People diagnosed with the disorder are said to be lively, dramatic, vivacious, enthusiastic, and flirtatious''
_Well we can throw the ''lively, vivacious and enthusiastic'' part out of the window, given her general stoic demeanor.
''HPD lies in the dramatic cluster of personality disorders. People with HPD have a high need for attention, make loud and inappropriate appearances, exaggerate their behaviors and emotions, and crave stimulation. They may exhibit sexually provocative behavior, express strong emotions with an impressionistic style, and can be easily influenced by others. Associated features include egocentrism, self-indulgence, continuous longing for appreciation, and persistent manipulative behavior to achieve their own needs. ''
_She fits the bill on most things, but definitely not the expressionistic behavior, manipulative behavior is possible since it's speculated she mainly dates Ian to climb the ladder to popularity and/or would drop him as soon as he's not useful any more in one way or another.
Granted, she did claim to have a personality disorder, I think it was BPD, but that's most likely a lie to make herself look interesting.
