Some of you may have missed Korranation.com having these episodes up to view as they were only up for about 3 days. Now Nick.com in advance of the new Korra section on their site has put up Episode 1 in full and half of episode 2.

So enjoy as the countdown to the Television Premiere grows ever nearer on April 14th.
Episode 2 is edited really weirdly, with various scenes missing, also it has a new shorter intro and a cool recap section.
