Amy was trying to get her kids to tell her the truth about something, so she used an interrogation technique on them.
She had them in separate rooms and would ask them the same questions to see if they gave the same answers. She would tell them that their sibling in the other room was ready to talk and tell the truth about what happened, but neither of them budged.
Even though her kids don’t get along that well together right now, neither of them ratted each other out and kept telling her they didn’t know the information she wanted. She thinks they are that way because of their time in the orphanage and they had 75 kids there, so they were always looking out for each other.
