He seems not just quiet to me, but unimaginative, unoriginal, humour-less... a disciplinarian, an authoritarian... and fairly crude and brutal at times, even if it's forgivable as a result of brutality. All of this may just be the surface characteristics of a proud, passionate, strong and committed soul, but it comes at a little too high a price.
Can't really imagine what Moonshade ever did with him before they had Chitter. Plant him somewhere and throw herself around his neck? *G* sorry. Thing is, I can see his personality as a huge part of his sex appeal... but not as very attractive otherwise. Not expecting anyone to agree, of course.
