Isn’t much of the power of the Maiar in diplomacy and setting events in motion? Gandalf was as much of an interloper and manipulator as he was anything else, and his hiring Bilbo as a thief was the penultimate piece of his mission, as inadvertent as I’m not entirely sure it was. Right? No, really, I’m kinda asking, I don’t know for sure.
The finale would leave loose ends as long as the cables they’re frayed from, and season 2 will either be canceled or cut short so huge compromises will have to be made and nothing is properly resolved
