[Narvin is taken aback by Kay's sudden focus on him. And by what seems to him a bit of a non sequitur, although the way Kay says it Narvin's thinks that he's following a very clear train of thought, just not one Narvin himself is privy to yet.]

We have a large number of time senses, many of which are fairly rare in sentient species. We're also very sensitive to sensations of motion and gravity. I can feel the gravitational pull of this planet, and the moon above, and all of us spinning through space. We also possess a keen sense of taste compared to many races, to the degree that if I really needed to I could detect the specific chemical composition of soil residue by taste alone, although doing so is uncouth. Not to mention it tastes rather disgusting. Our sense of smell is likewise strong, as taste and smell are tied together.

[He ends with a shrug, wondering if any of that was helpful for the hypothesis Kay is pursuing.]
