The concept was a rural, almost abstract landscape at dawn, with rice paddies et all. Zuko and Toph (in their twenties) would be on a crumbly old wall overlooking it and framed by bonsai or cherry blossom branches (with the pink adding contrast to the scene).
Zuko's relating a humorous anecdote, gesturing with a hand and Toph finds it all pretty funny. Ultimately its a quiet moment in the early morning with just the two of them.
