Tiercel

Ran around and did some other side quests, came back, and now he's there! Not sure what I did (talking to the police chief again?) but everything is good now. Just to throw this out there: Loving the game so far! Kudos!

I have defeated the Taka/Zel double battle at the third PULSE tangrowth, and I go to Corey's gym but he isn't there. I solved the color tube puzzle, opened the back room, and there's no one there. I'm not sure if this is a glitch or if I've missed some story point... I did not save all the police officers before defeating Taka/Zel, I did that immediately afterward, even before going to Corey's gym. From what I read, this changes the story a bit. Am I missing an event that puts Corey in the gym, or should he be there? Thanks in advance.
