This is why I love Zuko. He's been through so much, and it's understandable to see him make choices you know he probably shouldn't make, but he's always been a good guy, and his uncle was the only person to see that for a long time; not even Zuko knew. I love this scene so much because Zuko is so humble and brave. It couldn't be more perfect.
For all you fans of the movie #Avatar - James Cameron is making three sequels! "2016, 2017 and 2018?!?! Sheesh! At least they'll be released in quick succession once they are FINALLY released". - "IMDB, as of May 2016 - The release dates have been pushed back again...sigh. 2018, 2020, 2022..."
