"Yeah, but you weren't really jumping to tell me, either. How did Scarlett know?" That was a good question, if you ask him. Why did Scarlett know, and not him? "And with the way you sound, you wouldn't even be able to lie about it if you wanted to." She hadn't lied to him, no, but she just... didn't tell him something, and he felt it was almost like lying by omission type thing if she was going to try and hide it from him later when he would have called.
