You can bunny Frederic, he's an NPC, even if he's my creation. He will act rather emotionlessly, maybe a bit worried, and take you out the back door from the gym, to the Dancer's Studio in Ecruteak. You know, the house where the Eeveelution trainers dance. There he will ask you to wait, have a drink while trying not to talk to too many (yes, it's a bar) and look at the beautiful Kimono dancers and their pokémon until Chinika and the other leaders arrive. You can play it out as you wish, but that's what "Freddie" will try to make you do, since Chinika has instructed him so.
