It's a little too convenient. All tied up nicely thank you for asking... Why does everything need explaining? Where's the mystique? It's ten years since Panaka's day with Padme. Maybe the buggar just retired and the Naboo employed a new bodyguard or something, very mundane like civic duties are. I really hate to be talked down to like this in movies and plays and whatever else. I always have hated everything being sorted out so tidily ever since I was a kid. kids will see through this in a trice. Kids are more cleverer than Lucas is crediting them with being. And if they hadn't found out that Typho is the nephew of Panaka they would have made up their own reasons if they had a chance. Seems Lucas has robbed kids of a little bit of imagining here. Big fat hairy shame for the kids.
