Don't know only gets a small twinge back of his shoulders. It's the expected response and he mirrors it back in kind, ready to roll it off both of their backs and go on to a different thing. Elaboration, though.

It sends him looking at Russia's feet, because he knows that eyes can be too difficult but wants to let it be known that he's paying attention. Strict attention.

So he attempts it himself, still staring at boot laces.

"Howbout now."
