Zoravec was headed towards Kate's place, but the sudden obstruction made him halt. He paused there on the street and was ensuring that he would probably figure out who was spying on him. Although it was still unsure if somebody was actually spying on him or not. Because Zoravec was not able to pick any traces of anyone unusual.
Nonetheless, Zoravec' concentration was solely focused on the voices around him. It also enabled him to sense that a child on a cycle had been coming towards him. However, Zoravec knew if he stepped aside then whoever was spying on him would get alert. It was obvious that no human was able to sense such stuff. It has to be a dhampir or a vampire.
That's why he did not step aside instead stayed there so the child's cycle could bump into him. All to ensure that he was an ordinary human and the spy was just wasting his time. Zoravec knew the child was barely able to handle his cycle, because he could hear his sobs and irregular breathing.
