Avery is a very perceptive and intuitive person, which is why she realizes that she’s really about to get answers now. Something in Augusta was so important to Judy that she kept going back up until the Staffords put her in a nursing home. Presumably, she would still go back every Thursday if she could, which is why she has a standing reservation. Trent agrees to go with Avery, which shows how willing he is to go out of his way to provide moral or emotional support for her, unlike Elliot, who criticized her for digging around in her family history at all.
