Season one of Grimm was about Nick Burkhardt discovering he was a Grimm, and the Wesen world into which he found himself thrown discovering that what made him special wasn’t that he was a Grimm but that he was Nick Burkhardt, good cop. Season two was about expanding the mythology, up to and including the pivotal eventuality of those close to Nick learning what he was, beginning with his partner Hank and ending with his quasi-fiancé Juliette.
So what’s season three been about? In a curious way, it’s been about what was dramatized by the story that began at the end of season two: what happens when the Grimm becomes the monster?
Not that Nick has been a monster this season, but at this point he’s been a Grimm just long enough (and this despite his actions as a Grimm being tempered by being a good cop) that it’s beginning to go to his head. He’s beginning to find himself somewhat above the people around him.
It started when Nick decided not to tell Wu that he really saw what he thought he’d seen, somehow determining that he was not as capable as Hank or Juliette, and thereby being directly responsible for Wu’s hospitalization. It continued when Nick conspired to steal Adalind’s baby, somehow determining that there was no way to convince her, and what’s more no reason to convince her because everyone else already had an opinion.
As this season nears its end, Nick’s decisions have become increasingly paternalistic, as he takes it upon himself to decide what’s best for everyone else. He’s not the monster in the woods he was forced to become when the season began, but he’s certainly something other than he was when his journey into the world of Grimms and Wesen began.
The only question is whether the ramifications of these sorts of decisions rear their heads this season or next.
