You have to go over the golden bridge, and defeat the 6 trainers that stand in the way, once you pass them continue forward until you find Bills house. Pass his house and go up the stairs and you will 'interupt' Misty and Im assuming her boyfriend. She will then return to the gym. Use fly to get back to Cerulean City and battle.
