It was Alicia and her children (not T.J.) who went into the woods, though actually that is just what she told Mr. Jones. She was really meeting with Rich. He wanted to see her and the twins, but she was compelled to take Heidi as well to prevent her from telling Mr. and Mrs. Jones of the meeting. By this action, Alicia put herself in danger and broke the no-contact injunction. When Mr. Jones discovered what she did, he ordered her to pack her bags and leave (according to their agreement), because he was not going to allow her to jeopardize the safety of his family as well as her own.
