ok, first of all, i would like to say that i am new to this forum and i don't know the rules. so sorry if i did something wrong.
this may seem a little weird but I NEED HELP
after i had gotten the volcano badge, bill suddenly appeared and i didn't really pay attention to anything he said so I kept pressing the A button. so i ended up on 1 island and then i did everything i was supposed to and then went to the indigo plato and became the pokemon league champ. so i decided to go the islands again but i couldn't find celio in the pokemon ceter. what do i do?
