Just as I am about to open the black book Neloth says: "Don't worry, I'll be taking careful notes about what happens to you." Gee, thanks Neloth. Good to know my death will go to the advancement of knowledge!
Then just as I am leaving for Apocrypha, Neloth says "If you see Hermeus Mora tell him hello for me" as if he and HM were bestest buddies. I just cracked up.
I find his entire pompous self-regard to be quite hilarious. I also like how the voice actor captures that upper crust disdain for their inferiors "Are we done? I thought so." Great job with the voice acting.
