what kind of lie
When Extremes Meet is the best book 1 episode
Tarrlok goes mustache twirling villain for no reason, shutting down a whole nonbending district (the fact there's segregation legitimizes the Equalists for that reason alone). Then he locks up Korra's friends because the episode needed a reason for Korra to get angry. The episode is saved by the last fight and the bloodbending reveal.
And The Winner Is... shows the subtler, snakier side of Tarrlok, which is him in his element. Then you get the best probending of the season. Then you get glorious Amon swagger. Then you get the rooftop fight, praise be. The entire time Lin is Batmanning around. As a bonus, Mako is completely useless and Tahno is a sacrificial lamb. It's a great episode all the way through. Everyone is executing at top form.
