As soon as Izzy mentioned the dog, Riley stopped smiling. He leaned forward in his seat, looking at her intensely, and asked, "You buried a dog? Was the dog white? With no tail?" At first Izzy may have thought he was joking, perhaps trying to spook her like he sometimes did. But after a moment, she realized he was dead serious. What could a dead dog have to do with anything? It was a real dog, not an aberration. Trevor had seen it, not her, and he was a completely normal person.
