“You know, Prince Zuko, destiny is a funny thing. You never know how things are going to work out. But if you keep an open mind and an open heart, I promise you will find your own destiny someday.”—IROH to Zuko, 97 ASC
You can’t deny it that this pic of Zuko being all sweet with his little sister is very identical to this promotional still of Seita and Setsuko of the classic Ghibli film, Grave of the Fireflies. Even zuko’s relationship with kiyi is similar to the one the two Japanese wartime siblings have. I think the artists who drew this still for the comic book based their drawing off this Ghibli still.
