The Legend of Korra2012

Toph Beifong:
You said you saw your past enemies. Now why do you think that is?

Korra:
I don't know. Because they made me and a lot of other people suffer.

Toph Beifong:
Sounds like you're carrying around your former enemies. The same way you're still carrying around that metal poison. You ever consider maybe you could learn something from them?

Korra:
Sounds like the swamp's messing with your mind too.

Toph Beifong:
My mind is just fine, thank you. Listen, what did Amon want? Equality for all. Unalaq, he brought back the spirits. And Zaheer believed in freedom.

Korra:
I guess.

Toph Beifong:
The problem was those guys were totally out of balance, and they took their ideologies too far.

Korra:
Okay, fine. But that doesn't explain why they keep haunting me.

Toph Beifong:
Because you need to face your fears. You can't expect to deal with future enemies if you're still fighting the old ones.
