In the season 2 episode "Tales of Ba Sing Se", Iroh's story is about him mourning his son.
Iroh's original VA was Mako (who died before the season was completed), necessitating Greg Baldwin as a replacement.
I tried using the program Melobytes to create a short tune based upon an AI image I created. The tune is fine but the lyrics it came up with are bizarre. https://melobytes.com/en/
I want to thank the content creator Moon for showing me this program in a video he made showing Temu to have always been a scam.
