Rosalie almost winced when cupboards started slamming, but she stayed where she was, unwilling to back down or give in to his temper tantrum. They shouldn't have come together, her and Boyd. It was making him more defensive to have them both there, and yet she was unwilling to just leave them, since Boyd didn't think about what she was doing and Daniel didn't seem to know how to counter it, or was unwilling to.
So she continued to hang back, letting Boyd talk to him, telling herself that the other woman had known him longer and could deal with this just as well.
