The Legend of Korra, Season 1

Korra:
That's one of the saddest stories I've ever heard.

Tarrlok:
Avatar Korra. I am truly sorry for all that I've done to you. I thought I was better than my father, but his ghost still shaped me. I became a soldier of revenge, just like he wanted me to be. And so did my brother. The revolution may be built on a lie, but I think Amon truly believes bending is the source of all evil in the world.

Mako:
How did you figure out Amon was your brother?

Tarrlok:
When he took my bending... the sensation was somehow familiar. I later recognized it as my brother's bloodbending grip.

Korra:
So... he somehow uses bloodbending to take people's bending.

Tarrlok:
I don't know how he does it... but, then again, I've never encountered a bender as strong as Noatak.

Korra:
How in the world do we beat him?

Mako:
We can't. Any attack we throw at him, he'll redirect with his mind. That's how he's been able to challenge any bender.

Korra:
So much for our ambush. If we stay here, we're toast. But there's another way to beat him.

Mako:
How?

Korra:
This whole time Amon has been one step ahead of us, but finally we have the advantage. We know the truth about him. If we expose him as a bender in front of all his supporters.

Mako:
At the rally.

Korra:
We could take away his true power!

Mako:
And undermine this whole revolution!

Korra:
[to Tarrlok] Thank you for your help. [to Mako] We can't just leave him here.

Tarrlok:
Go. Amon can't know anyone spoke with me. Defeat him. Put an end to this sad story.
