Zuko was on the hunt for the avatar and you were forced to go with him because you were a strong firebender that could help him. Since zuko wasnt having any luck finding him you were extremely bored. Only thing was: he's liked you since you were kids. When you would play with him instead of azula always made him smile and get warm inside. Uncle iroh smirks when he sees you two leaning against the side of the boat. He sips his tea and walks over "Hows the girlfriend, Zuko?"
