Wow. Just... wow. Definitely the best episode so far with everything going on and it all clicked. Really dark, great characterization, some fun humor and deepening of the complexities of the Avatar-verse. I agree that things do seem somewhat rushed overall, but they're doing a great job telling the story nonetheless. Too bad the new Team Avatar had such a short run - Asami's car was pretty sweet. I don't think Tarrlok can be Amon, just because of his reaction to Korra saying they're alike, which we could see but she couldn't.
