Captain Saikhan becomes the chief of police following Lin's resignation.
Tarrlok is revealed to be a Bloodbender. He is the third known Bloodbender following Hama and Katara of the original series. He is also the first to be able to bloodbend without the need of a full moon.
Korra: You're a bloodbender?!
Tarrlok: Very observant.
Korra: But there's not a full moon. How...how are you doing this?
Tarrlok: There's a lot of things you don't know about me.
Bolin: I have a couple of questions: Is this an all vegetarian island? Is that where you train airbending? Do we have to wear air acolytes clothes? Do we each get our own sky bison?
And final question, how many trees are on this island?
Ikki: Yes, Yes, No, No, and 10,552.
Meelo: (while staring at Asami) You're pretty, can I have some of your hair?
Mako: Looks like I have some competition.
Aang, Sokka, and Toph from the original series appear in Korra's vision.
