I don't think there was any labeling... it seemed like useful observations to me. It's a shame there is so much confusion about narcissism, as it isn't intrinsically unhealthy! It's actually a problem if someone's healthy narcissism is wounded, so they are confused about their healthy entitlement etc. We do ALL have needs, and it's not so easy getting them met.
Sorry you are getting triggered @seesaw . This thread is about you, and your nephew. It's not clear to me how anyone can best support you with this. I really think you have done him lots of good, especially in getting him more appropriate treatment. Sorry that your brother isn't on the same page, and understanding where you're coming from. It does sound very upsetting.
