50 Shades of Honor
I actually think this became a running joke with Zuko and Aang in his later years.
Aang: Can you watch Tenzin for a few hours Sifu Hotman?
Zuko: I’m like 50 here Aang you can really just call me Zuko!
Aang: Alright, good luck and thanks again Zuko!
*Tenzin on his air bubble flys by*
Zuko: Well then it’s time to CAPTURE THE AVATAR …..’s son.
