Campfire

I don't think that there is a specific event during Omega Ruby that inspired a campfire scene, but the image is dated to December 2014, so it's possible I just forgot. That isn't to say that there aren't details that are inspired by actual events (e.g. explaining a Flamethrower TM spamming session via T4 obliviously handing out a Fire-Breathing Diner), but as far as I know, it's a partial group shot for the sake of a partial group shot.
