Eliot gives no sign that he's noticed the motion, other than to point his feet that direction and start ambling toward the indicated rainbow. Or rather, he looks like he's ambling, but he's actually going very carefully, because he has no interest in ending up in a pit, either.

"Yes, the voices, all talking with each other? ... you don't hear them? This is going to be incredibly embarrassing if I find out I've gone batshit and no one told me before now," Eliot complains, as if hearing voices is equivalent to having a bit of broccoli in one's teeth.
