Kay followed in silence, though he was most definitely keeping track of things like directions and exits and even number of people they passed -those he could actually see and those who he could only assume existed- because that was the kind of thing he did, and the myriad of statistical predictions he could get up to, even while recharging, would at least give him something to do so that he didn't end up doing something rash.
