What happens when Via get home after their first day of school?

Tensions are high at the Pullman house that night, because neither Via nor Auggie wants to talk about the first day of school. Via is very upset when Auggie cuts off his Padawan braid, believing that Auggie has lost a part of himself. That night, Mom is supposed to come and talk to Via about her first day, but she falls asleep in Auggie's room instead. Via recounts a time when she saw her mother just standing outside of Auggie's room in the middle of the night, like an angel watching over him, and wonders if her mother has ever done something similar outside of her own room.
