Sylvia heard Dirk's stomach, and she realized that he had missed more than just lunch. With what happened this morning and the night before, Dirk never had the chance to eat breakfast like she did! No wonder his stomach was growling so loudly! 
She patted his shoulder gently and she suggested, "Let's go get you some lunch, Dirk. I'll pay for it," She then looked to Toi, giving him a questioning look as though to ask him where they could get food. She wasn't sure if the inn was the only place where they could get food for Dirk.
