I doubt he is a narcissist, tbh.
He displays the inability to see anything aside from his own point of view, and I have seen him display some referencing behavior.
I dont think he suffers from Narcissistic personality disorder
http://en.wikipedia.org/wiki/Narcissistic_personality_disorderDSM-IV-TR 301.81
The Diagnostic and Statistical Manual of Mental Disorders fourth edition, DSM IV-TR, a widely used manual for diagnosing mental disorders, defines narcissistic personality disorder (in Axis II Cluster B) as:[1]
A pervasive pattern of grandiosity (in fantasy or behavior), need for admiration, and lack of empathy, beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:
1. Has a grandiose sense of self-importance (e.g., exaggerates achievements and talents, expects to be recognized as superior without commensurate achievements)
2. Is preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal love
3. Believes that he or she is "special" and unique and can only be understood by, or should associate with, other special or high-status people (or institutions)
4. Requires excessive admiration
5. Has a sense of entitlement, i.e., unreasonable expectations of especially favorable treatment or automatic compliance with his or her expectations
6. Is interpersonally exploitative, i.e., takes advantage of others to achieve his or her own ends
7. Lacks empathy: is unwilling to recognize or identify with the feelings and needs of others
8. Is often envious of others or believes others are envious of him or her
9. Shows arrogant, haughty behaviors or attitudes
I know he seems to have some of the signs, but I don't think he ticks enough of the boxes to be classed as having NPD.
I do like Duke, so I mean this in the nicest way. He does have a problem, but I don't know what it is. I do think he needs to seek help.
