The Legend of Korra, Season 3

Zaheer:
(smiles) It seems Aiwei was mistaken: he was followed.

Korra:
That's right. We knew he'd lead us straight to you. So what did you do with him?

Zaheer:
He'll be spending eternity in the Fog of Lost Souls... which just leaves the two of us.

Korra:
(raises her fists) Don't move, Zaheer! You're gonna give me some answers!

Zaheer:
(sits down) There's no need for aggression. Neither of us has our bending, and I'm not going anywhere. I'll answer whatever questions you have; you deserve that much. (Korra lowers her fists, surprised) What would you like to know?

Korra:
First off, who are you people, and why do you keep trying to take me?

Zaheer:
We are part of a secret society, dedicated to restoring freedom to the world. We... are the Red Lotus.

Korra:
Red Lotus? Are... you related to the White Lotus?

Zaheer:
We are what the White Lotus was meant to be. But after the Hundred Year War, the White Lotus lost its true purpose. Its members came out of hiding, and openly served the Avatar. They became nothing but glorified bodyguards, who served corrupt nations. So a great man named Xai Bao broke from the White Lotus, and began his own society.

Korra:
(sarcastically) That's a great story, but it doesn't explain why you tried to take me when I was a kid.

Zaheer:
That... was Unalaq's idea.

Korra:
(surprised) What? My uncle was part of the Red Lotus?
