~No his name is Bill, but yeah what he said :)
After you beat the seventh gym, on Cinnibar Island, a ship will pull up on the east (right) shoreline, and Bill will come out and ask if you want to come. Say yes, and he will take you to One Island and introduce you to his friend, Celio, who will send you on an errand. Bill will give you the tri pass (giving you access to islands two and three, as well) to help you complete the errand.
