What are three things we learn about Crow in the beginning of Chapter 19? Why are these discoveries so important? (think about how this relates to a theme of the novel)

Back at Sunset Towers, Otis tells Crow he's figured out who the bomber is: James Hoo. Crow vows revenge on the person who damaged Angela's face. In Shin Hoo's Restaurant, Jake Wexler eats lunch and talks with Madame Hoo; Grace Wexler feels unexpected jealousy. Crow enters the restaurant, pretending to be there for lunch. When James Hoo asks about her health, she grudgingly tells him about her sore foot. He brings her a pair of his newly-invented paper innersoles as a gift. The innersoles give immediate relief to her sore feet, and Crow concludes that such a kind man could never be the bomber.
