mask

sth quickly made. I just couldn't wait (; I have to make up all the drawings for Zutara Week (did I use the proper phrasal verb? sorry if not x)
So, here's the short explanation. Both, Zuko and Katara, had the same idea of wearing the masks of the other's boyfriend/girlfriend, so no one could suspect anything. Of course they didn't know about each other's plans.

and, sure, no one would suspect anything. who cares that they're wearing their usual outfits xD
