He actually felt worried if, for example, Dexter Franklin suddenly found out about his whereabouts. By now, she and Jasper had indeed gone far from New York. But the uneasiness kept haunting him.
Stella, she really didn't want the happiness she was feeling with her husband to suddenly disappear, just because of Dexter Franklin, her husband's ex-boss. And when Stella got a taxi and headed home, she was relieved that no one seemed to be monitoring her. And he also does not want to go far from his house, if there is nothing urgent, he must do.
