As to the bad, I have observed things second hand that i wasn't to happy with Nero. I can say that I think he is one of those people who will sometimes avoid saying things to avoid a fight or conflict, when really they should be out in the open.
That being said, I have to say I am glad to see him when ever he is around. He has a quick mind and a quick wit and are one of the more pleasant people I have ever hung out with. I am proud to call him an old friend(one might say ancient)
