 Well, Dr. Peralta was in love with Ruth without even knowing she existed. How interesting. He romanced you and finally asked you to marry him. He didn't know they were twins. All he knew was that every now and then the girl at the newspaper counter brought him a warmth that he missed at other times. And that's what puzzled him. That's why he asked me about a split personality. You weren't aware of this until that night in the apartment when he spoke of this curious difference from time to time. Then you knew what had happened again.
