The robot might or might not understand anything. The ghost is finding this human's behaviour quite familiar. (Poor Shyren. He ought to go visit her, once he finds his way back to Waterfall. Maybe she and the human would even get along!)

He knows better than to say anything about how quiet they are. Instead, he goes with, "I love your truck, darling! It's so vivid." He means it. Red is a close favourite colour, after pink.
