oooh found this after googling it !...
It was at this arcade that Judy had a fateful meeting with down-and-out Zoe Tattershall. Zoe fell pregnant, while Judy had been told she herself could not have children because of an abortion at the age of 16; so she and Gary agreed to buy Zoe's baby Shannon (whom they renamed Katie), the money for which Judy obtained by sleeping with her boss at the arcade. When Gary found out about this, he left. He and Judy were reunited when Judy announced she was pregnant - with twins. Shannon eventually went back to live with Zoe, but the good news of Judy's pregnancy was overshadowed by the death of baby Shannon from meningitis.
