You know I was thinking about it but that would make him Tenzin's cousin...people on Tumblr were going on about him being his nephew...I don't know haha.

He does seem a bit on the young side to be Zuko's son...but also I am not sure why Zuko's child would name their child Iroh, since I don't know if they even would have met him...

And yeah...his voice sounds very young for his face haha...I thought so even for Zuko really...and he was what, 16?
