how does moon shadows point of view of his father change in chapter 5

Windrider goes to the building where the gang Black Dog belongs to lives. When Windrider explains the situation to their leader, they bring Black Dog out to fight Windrider. However, two of Black Dog's friends wait in the alley to ambush Windrider. Moon Shadow sees them and tries to stop them, forcing his father to kill these men. The leader of the gang tells Windrider that Black Dog is no longer a member of their gang and he can be killed without retribution. However, the friends of the two dead men will more than likely look for retribution, therefore Windrider should get out of Chinatown. The following morning, Windrider announces his decision to move and live in the city with the demons.
