After a while, Kyo started to wonder how everyone else was doing with the assignment. He took a look around to see Katherin and Pyktis at what seemed to be a bit of a standstill. Now that he thought of it, how exactly would they go about the assignment? There couldn't be much help in writing equations down on paper if they couldn't be seen, could there? He wasn't really sure, since he wasn't blind himself; maybe writing it down would still have some value. 

As curious as he was, he felt a little awkward, as if the answer was probably obvious and he should already know it. The fact remained that he didn't however, and while asking might make him seem air-headed or painfully ignorant, it couldn't be worse than showing callousness by just assuming in either direction, right? And then there was the fact that they appeared to not have even started yet... 

After thinking it over a bit more, the wondering boy reached for his tablet and typed out the question that preyed on his mind: "Katherin, Pyktis? Is it easier to work with spoken proofs, by any chance? Or do you use a different method for something like this assignment?"
