"Really!?" It was Aang's turn to be surprised, though his came in the form of an exclamation. It certainly did explain the clothing Zuko was wearing. He had to wonder how he got into Ba Sing Se in the first place though. After all, he doubted the people would take kindly to Firebenders especially if it were a Prince from the Fire Nation, banished or not.

"What were you doing in Ba Sing Se?" That was the question Aang decided to ask first, he still had plenty of others buzzing in his skull but it was to be expected. Why would he go to Ba Sing Se in the first place? The only reason Aang could think of was to capture him but Zuko had said it might have been before he had even arrived!
