I'm probably a minority on this one, but I wasn't even that into Nicholas Blair...nothing wrong with Humbert Astredo, I suppose there were just too many supernatural beings running around during the Adam storyline. Maybe I would have enjoyed him more if there had been no Adam and Eve subplot and it had just been Cassandra & Nicholas vs. Barnabas & the Collins family. He had too many scenes with Adam & Eve, and they both drove me up the wall.
but looking back on it humbert astredo brought alot of nuance to the character of nicholas blair and his scenes with lara parker were often excellent.
