He was quickly capture and taken to jail, shaming his family. Years later, Wu Kong escaped and was even trying to steal money from his own mother while she was asleep. Monkey, now training at the Jade palace, caught him stealing and begins to fight him. During their battle, Monkey left a scar on Wu Kong's face. Monkey's mother wakes up and see her two sons fighting, which breaks her heart and causes her to collapse. Wu Kong quickly leaves yet again and disappears into darkness. Soon before she passed on, Mother's mother makes Monkey promise to protect the family.
