[It's silent, on Korra's end of things, as Wan tries to connect. She almost can't take it.]

Wan, I'm serious. At Harmonic Convergence, Raava was torn out of me and... destroyed completely. The line of the Avatar was broken. I was able to pull her from Vaatu and merge with her again, but I still have no connection to you. Or to any of the past Avatars. I think... I think that did something. To her. To us.

[Korra's next words are a choked sob. She's hardly even taking into account that this is public.]

I'm so sorry.

[Even in victory, she's failed.]
