Sparrow isn't actually the troublesome actor teen everyone thinks he is. That's just who he is right now. In reality he is the maker of this world. He created it, and then watched the chaos unfold. He is also the only one who knows everything about Wolfgang and Buddy's past. What they were, who they were, how they knew each other. Everyone else... well, due to unfortunate circumstances he had to punish them.
Currently he is playing at being an actor, and landed a spot in the same TV show as Wolfgang and Buddy. Was that intentional? Yes, yes it was. Part of him feels the tiniest bit of responsibility to them. Like maybe, since he's the one who decided to reincarnate them as humans before letting them take their parents' thrones, maybe he should keep an eye out for them. Or toy with their lives, that sounds fun too...
