fic concept of Zuko actually capturing the avatar and Aang was imprisoned by the fire lord, kept under lock and key but it doesn't sit right with Zuko even though his honor has been restored and he has everything he could possibly want, so he starts sneaking in to visit the Avatar ( perhaps as the blue spirit at first or some sort of concealed version ) and slowly begins to learn about Aang and his culture and the guilt weighs heavier and heavier. ( might work on this later)
