I've been sort of annoyed with the way Monroe is written so nerdy and dorky, when the very beginning of the show seemed to be portraying him as a very dangerous individual who buries that aspect of himself beneath harmless affectations, but on the other hand, Silas Wier Mitchell's performance is one of the highlights of the show, so it evens out. This new episode, however, kind of highlighted the problem with a long network-series season: they try to draw the crises and problems out too long. Once they got everyone in the right place to talk things out, the spell-triangle was fairly simple to resolve, and also contained the seeds for a big leap forward in Nick's understanding of his place in the show's mythology. But they spent the whole 2012 part of season 2 dithering, and it was getting frustrating. I think the flaws in Grimm are due in large part to its format, and within those limitations, they do a good job.
