The Legend of Korra, Season 4

[Korra sits on a tree root, having encountered visions in the Swamp of her enemies at moments where they did her the most harm. Toph walks up to her.]

Toph:
There you are! You got my dinner yet?

Korra:
No ... this swamp ... It did crazy things to my mind. I had visions, of all the times my enemies hurt me.

Toph:
[nonchalantly] Yeah, I figured something like that might happen.

Korra:
[surprised] What? You wanted me to see those visions? You are one twisted old lady, you know that?

Toph:
Look, I know you want to get better. And so does the Swamp! It can sense you're out of balance. It will teach you what you need to learn, if you're open to listening.

Korra:
[sighs] Okay, Swamp, I'm all ears.

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

Korra:
[unconvinced] Sounds like the swamp is messing with your mind, too.

Toph:
My mind's just fine, thank you. Listen: [as she speaks, images of each of Korra's enemies fade in and out] what did Amon want? Equality for all. Unalaq? He brought back the spirits. And Zaheer believed in freedom.

Korra:
I guess ...

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