One of the reasons for their misunderstanding was because of younger brother Justin . Kitty supported his decision to join the army whereas Nora was completely against it , especially after Justin was deployed to Afghanistan . From that point until Kitty 's return to Los Angeles the two had barely spoken to each other . Until she returned for a visit for her birthday , Kitty had not been home in several years . She had been living in New York City , and witnessed the fall of the Twin Towers during the September 11 attacks
