I loved that line! Why aren't there more like this? I'm sure Katarra must have seen some of Aang in Korra. She's the one who trained both avatars in waterbending. It just makes me sad to think Katarra is so old and alone, and that Aang has to have been dead sixteen years. Last time we saw them they were barely teenagers.
You've just reminded me of that scene in Last Airbender. That's so heartbreakingly sweet that Toph and Aang are somehow continuing their unbreakable friendship beyond life and through the next generation. Thank you for this gorgeous comic.
