Honestly, I don't mind one way or the other. Zac's story doesn't truly begin until CoM at the earliest, KH2 at the latest, depending on whether or not we do CoM (and I'm really, [i]really[/i] hoping we do because I've got [i]ideas[/i] brewing), so there's no pressure for him to go to any world over the other. Right now, his role is guide/mentor/protector/chauffeur, so he's happy going with whoever wants him/needs him the most
