Well I made a topic just like this and didn't notice this one until after, Here are the Q's I posted on there:
Hey everyone hows it going?
I just finished watching the ifnale and I gotta say I have mixed feelings about it. It certainly puts a close to that story but of course everyone has been left with tons of unanswered questions.
1. The Whereabouts of Zuko's Mother
Personally I think we will find out about Ursa one way or another. It almost seems cruel to have Zuko ask where his mother is if they had no intention of revealing exactly what happened to her after she left the Fire Nation. Ozai said she did treacherous things the night she left, so I am guessing she helped Ozai kill his father so he could rule.
2. Will Aang ever find out that he and Zuko are related?
I know technically they aren't really related, and I know it probably wont mean much, But I found that was very shocking to learn in "The Avatar & the Fire Lord" that Sozin and Roku were best friends, and now Zuko and Aang have become friends as well but it'll probably turn out for the good unlike with Sozin and Roku.
3. Iroh's trip to the Spirit World
I know the creators say they wont talk about this, but it seems like something very important. The Spirit world is just for Spirits and the Avatar, so having a regular person visit it must have been a very special occasion. Perhaps he visited the spirit world to plead for his sons life back? Or perhaps he visited the spirit world before his son died and he got a warning about it? I was also shocked that Iroh didn't have that many scenes in the final in general.
4. Koh the Face Stealer
I could have sworn I read something saying that he would make a return for the finale. Unless they were talking about the brief flashback when Aang talked to Kuruk, I didn't see him back at all. He remembers Aangs past lives so he must have some more interesting stories about him that might have some signifigance in todays world.
5. Azula
I think out of all the questions, this one could go either way. Azula has no friends so most likely she will end up in prison for life, but then again Zuko might start acting more like Aang and try to forgive her which could open the door for another rematch with her brother. I don't think she will come back but theres always the option since she isn't dead.
6. Ages of certain characters
I never really thought of it before, but I am starting to wonder what the ages are for Iroh, Ozai, and Azulon. Ozai looks no more than 50, Azulon looked to be about 80 when he died, yet Iroh looks to be in his 60's? I am guessing theres a big age difference between Ozai and Iroh but Iroh almost looks as old as his father. I know it wont matter much to the story but now that I thought of it, I can't make heads or tails as to how old they all would have been for it to make sense.
7 Toph
In Season three she seemed to slip into a background setting and only had one liners every now and then. I even felt bad when she was trying to open up with Zuko but he wasn't listening. I felt like she was underused in season three, and it would be nice to see her go back home and her parents let her live a normal life.
8. How long is Zuko's vacation?
I mean the guy just got crowned Fire Lord after a 100+ year war and he goes straight to Ba Sing Se to hang out with the GAang? Geeze don't you think you should start rebuilding or something? (not a serious Q just for jokes)
9. Will more people be able to Spirit Bend?
I don't know the logistics of it obviously, but if Aang has kids would they possibly be able to spirit bend? It seems like spirit bending is far more powerful than other bending so I hope it doesn't take Airs position. Also I wonder if that was a one time thing, or if Aang could go around willingly taking away peoples benidng powers.
Those are a few questions I came up with while watching the finale. The one thing that I lol'd at was one review I read saying that you get a real sense of Aangs story coming to a close....The guy is 12 years old how can they think that? Hopefully they do a show that starts out with Aang as an aged man, then they do flashbacks showing his life after the comet. They way we could get a real sense of Aangs journey ending.
I also hope they show the start of the war against the Air Benders. I know they can't show all 100 years of the war, but it would be great if we could see what the world was like before Aang was woken u from his sleep.
Sorry if there are topics like this already, but I guess I wanted to be selfish and make a topic so poeple would actually see it, instead of it getting lost in a sea of pyramid responses in all the other topics.
