Tenzin and Korra in “Unfinished Business”

Tenzin

Now that you're bonded with Raava again, are you also reconnected to your past lives?

Korra

[pause] No. I think that link is gone, forever.

Tenzin

I see. Why don't you close the portals, then we'll head home.

Korra

Maybe I shouldn't.

Tenzin

What do you mean?

Korra

What if Unalaq was right when he said the Avatar shouldn't be a bridge between the two worlds? What if Avatar Wan made a mistake when he closed the portals? What if humans and spirits weren't meant to live apart? [to Tenzin] Well, what do you think I should do?

Tenzin

[places his hand on Korra's shoulder] I think you should trust your instincts. There is nothing else I can teach you. You are the Avatar. Whatever your decision, I support you.
