Jim Calhoun and his sister Lori are just two Americans in North Abarra exploring their roots. They are definitely not off-duty CIA agents.
Enzo da Silva is the head groundskeeper on Princess Odile's country estate. He is definitely what he seems to be - the guy who trims the hedge maze and measures oxygen levels in the national forest.
The Princess's birthday bash is a major celebration every year. As the big day approaches, a series of accidents plague the preparations. It's almost like someone wants things to go wrong. But it's not as though two commoners like Jim and Enzo - with absolutely no super powers - can stop a rogue supervillian. And if Jim and Enzo keep showing up at the same crime scenes, it's not because they can't keep their eyes off each other.
Definitely not.
