As distracted as he had been, it takes Kelvin a second to realize that he had been addressed, and he tentatively pokes his head out from behind the relatively large tome he had been studying and scribbling within, perched upon a log a little ways back as he is, and then blinks uncomprehendingly down at the bowl that had been nudged his way for a moment. He then catches on with a start and scrambles to put away his book and writing utensils.
"Oh! ah, thank you very much! I might have f-forgotten to partake at all if left to my own devices. Heh," , he then takes up the bowl and begins to eat, taking dainty little spoonfuls and blowing on them for a few seconds each before placing it neatly into his wide, semi-tusked mouth.
With no book to hide behind, he is then faced with the prospect of socializing, and it seems the sharks can smell blood in the water, as it isn't long before the first query is posed in his direction. Trapped, clearly expected to reply, and with no convenient salvation via ambiguous grunts in sight, Kelvin sighs and resigns himself to making conversation and makes the dive.
"Oh, th-this little thing? Why those are just my notes. Observations, illustrations, thoughts and, uh, ideas and such. Much of my craft requires a bit of trailblazing new ground, ah, as it were, and is a little different for each practitioner. A-as such, I wouldn't get much of anywhere if I didn't entertain ideas now and again as to what my next project might be... so ah, well, I was simply reviewing and expanding upon some thoughts, that is all."
At that he gives a shyly dismissive shrug of his wide shoulders, and then engulfs another tiny spoon within his gray-green maw.
