How long has the guard, in their current form, been together? Seems like Ana is the newest addition to the guard, though most were recruited when the king and queen departed. This begs the question of what happened to the old guard, did most of them leave with the king and queen and leave the head guard/royal adviser?
On a side note, I'd imagine Donovan would try to be on everyone's good side, with mixed results. He'd be against actually forming any rivalries if he could help it.
Edit: Actually, what about Pokemon relationships? They are supposed to be our secondary (and possibly tertiary) characters after all, it's fair to think that they'd talk amongst each other, even if they can't talk to humans!
