Before entering the house, Edwin suddenly stopped Caroline. "Because she's much stronger than ordinary people and she didn't want to come with us, we had to use some unconventional means to bring her here."
Caroline was naturally aware of Eva's situation. If she showed any signs of resistance, ordinary people would not be able to handle her. Thus, Caroline was very curious about what 'unconventional means' Edward was talking about. As soon as she entered the room and saw the situation in the living room, she knew.
Eva's entire body was tied to the bed with large bandages. She was carried over, and it looked like they were dealing with patients in a mental hospital.
