Season 2 has been an interesting beast. Whereas Season 1 was an exclusively linear straight-shot with one character's story arc in mind (Gary's), this season's been intent on branching everything out, incorporating a larger cast with more varied backgrounds and working to do justice to each and every one of them, all with a more episodic format. It's admittedly been more of a mixed bag, creating some of the strongest and weakest entries in the series so far, but with "The Sixth Key" tying everything together, I'm happy to consider the past season to be, by and large, a triumph.
Last season's finale was the peak of Season 1's tragedy, a massive downer that picked through the show's cast and left them, at least by (incorrect) assumption, for dead. With Season 2 being a more optimistic season overall, though, it makes sense that it would end on a more hopeful note. It's a pleasant surprise, and while no doubt filled with some heart-wrenching moments, it's never too cruel; there's a sense of progress, and of all of the past twelve episodes' work gelling into one concentrated effort.
