I think people needs more than one or two facial expressions to survive in the kind of world that Lucius lives.

In some ways is an insult to think of Lucius as a uni-dimentional? charater because you just can´t live the way he has, as a simply EBIL VILLIAN, you need skill and inteligence and, and a goddamn brain! to do the things he has done, to be who he is, to believe and support and fight for what he does. In a very lucius kind of a way of course :).
