Rebecca's father found out about her visits to Kinkow and banned her from seeing Boomer. Boomer, Boz, and Mikayla traveled to Chicago to plead their case, but were attacked by Mary Ann and some Tarantula Warriors.
During the battle, it was revealed that Mr. Dawson is actually Paka Tui, an exiled Tarantula Shaman who was part of a group who didn't agree with their people's violent ways, and sought refuge with Boomer's parents. Boomer's parents helped them escape to Chicago. The real reason he didn't want Rebecca and Boomer to date was that if the Tarantula People discovered she was the daughter of a traitor, they would kill her.
