So Iroh never found Lu Ten again?
Sorry if this is addressed somewhere else, I didn't read the comics.
I was rewatching the OG show and cried like a baby on the Tale of Iroh when he says "Happy birthday, my son. We will meet again".
Then I moved on to Korra, and we see Iroh on the spirit world... We know (?) that he was so spiritually evolved that when it was his time to pass, he just went into the spirit world.
But does that mean he never found Lu Ten?
I don't know if the spirit world is where the souls go after dying, but I imagined no, for some reason. So by going to the spirit world, Iroh wouldn't go to the world of the dead and would never meet Lu Ten again, and that broke my heart so deeply.
Are there any theories on this?
