Hmm, no, I didn't mean more humourous, I mostly meant I thought his language would be a bit less formal, and more flippant and flirty. I think before he had to beocme the D'Rekta, he was a bit like those boys up the back of the class who never tak much seriously, and giggle when the teacher says soemthing remotely obscene.
But maybe that's just me. :)
