Donut reveals that Beatrice possessed Asher's photograph and hid Carl's half-brother from him.
After recognizing the hydra's heads, Donut explains that Beatrice kept Asher's picture on her phone and discussed the boy with her mother. Carl tells Donut that Asher was not Beatrice's nephew but his own half-brother.
Carl infers that Tami-Lynn probably contacted him through an account Beatrice secretly monitored. Beatrice therefore saw the attempt and deliberately concealed Asher's existence, possibly because she feared Carl would leave for Iowa. The discovery produces Carl's first sustained anger toward Beatrice even as he struggles to imagine a kinder explanation.
