Three moments: KOTBW - affected by guilt (Kureel). This was something fantasy/"adventure" stories rarely seem to deal with at all.
His & Moonshade's bit in Dreatime.
All things considered, though, he'd drive me up the walls as fast as Pike would, or Skywise's sunshine trio.
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.
