Molgrug remarks, nodding enthusiastically at Shillereese's eloquent speech which he had definitely been listening intently to, rather than studying the mortals and their paltry collection of offerings. "Also, has anyone been taking minutes of this meeting? I think next time we should nominate a, ah, a scribe, as it were."
