It can be assumed that he will eventually, but it is never said, nor are the whereabouts of his mother.
no, but there is going to be a new series, and i think it is going to be about zuko finding his mother
Yes He did!
A lot of series end that way and that is intentional. However, Aang, Zuko, and the gang, along with Azula, set out to find Zuko's mother in a 3-part graphic novel series named "The Search." SPOILER ALERT: Zuko's mother IS alive!
Sadly no...
no, Zuko never found his mother, but the writers from Avatar: The Last Airbender are making another Avatar series called Avatar: The Legend Of Korra which takes place 70-75 years after Aang. maybe on the first episode they will show Zuko finding his mother, but I'm not all that sure
On his father's side, Zuko had one cousin, Iroh's son Lu Ten. We don't know if he had any cousins on his mother's side.
Unfortunately, Zuko likes Mai, though we all know someday him and Katara are going to get married and live happily ever after!
You never know in the last episode Zuko goes to ask his father where his mother is and they cut it there this is exactly why they should make a book 4
Zuko was seriously injured in the final battle, but he was healed by Katara before his injuries could even take his life.
Zuko asked his father where his mother was in the last episode because he doesn't believe that his mother is dead and that his father is hiding something about her. Zuko's mother used to care about him more then Azula and she just vanished over night without saying bye or anything. Also he hasn't seen his mother since he was a little boy, and wanted to the truth and now feels confident to ask his father now that he is Emperor. -Signed Avatar the last airbender freak.
Its not fire, it is just the swords going in slow motion. If you look ahead to when Zuko and Jet are fighting back to back you will see that both of them sometimes have those flashes, so it is also the swords going really fast. It is not blue fire bending though.
It is never made clear why Ursa left, but it can be inferred that she was forced to betray Ozai, the Fire Nation, or both in order to save Zuko from being killed by Ozai.
