She Was Inaccessible
Philip informed him that Jessica was always in the neighborhood looking after the children, and he had seen her drop them off at school. He wouldn’t argue that; she has new friends, but he thinks that shouldn’t be a problem since he wasn’t always there. Maybe she’s just trying to be social for her own company. After hearing all of that, he was relieved. But why wasn’t she accessible at all times? He promised to attempt to spy on her. He was willing to take the chance, even though he knew it would cause them both problems.
