"You're too old to be me!" This Sokka not only has a Fire Nation emblem keeping his topknot up, but he also has a fantastic black shiny sword.

Which he is really not going to use on someone (or some THING maybe it's KOH) who's holding two babies, especially if the babies show such good taste. The one that's reaching for him gets given a bug-eyed stare for a moment before he returns his horrified gaze to the other boy's face.

"...and you messed it up! That's my face and you damaged it! What did you do?"
