Team-Ager = Teenager

Holden asked Joel what a Team-Ager (teenager) was. Joel explained that when you turn 13 you become a teenager and remain one until 19. After this explanation Holden lit up and exclaimed "OH! I thought there was a TEAM-Ager and I wondered how you got on it!" (this has been a hot topic because Gray is now a teen and has an appealing life from the twins perspective and they want to have the same rules as she does)
