The Legend of Korra, Season 3

Zaheer:
(whispering) Avatar Korra. Misty Palms Inn. Find her.

P'Li:
You two go. I'll stay and make sure Zaheer's body is safe. (Ghazan and Ming-Hua leave)

Zaheer:
(to Korra) I met your uncle when I was a teenager, after we had both joined the Red Lotus. We learned about Raava and Vaatu, and how Avatar Wan foolishly severed them, disrupting the balance of the world forever.

Korra:
(angrily) Avatar Wan wasn't foolish! He was trying to restore balance!

Zaheer:
He closed the portals, severing humans from spirits. Even you realize the error in his ways.

Korra:
So all along, you and my uncle planned to use me, to open the portals and release Vaatu?! That's why you tried to take me when I was a kid?!

Zaheer:
Yes. And with members of the Red Lotus as your elemental masters, we could've taught you so much.

Korra:
Sounds like you wanted to brainwash me, so I'd do whatever you wanted.

Zaheer:
No, Korra. All I wanted, was to show the Avatar a better path for the world.
