Just because Katara forgave Zuko and helped each other out defeat Azula does not imply a romantic relationship. Its true that they developed a special relationship late in the season doesn't mean that they are more than friends.

When I saw the title, I thought you were really talking about Air Ships.

Toph still has Iroh. Tiroh 4ever.

Naww it ended up perfectly the way it should've been. Katara and Aang were meant to be together from the start. For you people who keep saing Zatara there are like two episodes the seige of Basingse and actually that's about it. Look at Kataang, the very first episode where sokka jokes about him bein her boy friend, the forutne teller where she says that katara is going to fall in love with a powerful airbender only to come to a realization that it's aang at the end of the episode, or the tail of the two lovers where katara is clearly flattered by the thought of kissing aang or the day of black sun where they kiss, or the fact that katara has implications of being with him just not during the time of the war in the fire island players and so many other countless episodes. Case made.

OH I almost forgot, and the episode where aang enrolls in a fire nation school and he's dancing with the girl from class and katara gets jelous when sokka says that they looked good together; and the connection aang and katara make when they dance together

There was a big clue on who Zuko will end up in 'Boiling Rock'. Zuko would be worse than a jerk if he didn't wind up with Mai.

Ships destroyed?

Nah, they're just proven not to be cannon.

Oh well, I'm a Toko shipper, so I never expected my ship to be official.

You guys are all forgetting that Toph hugged The Duke right at the end of the Finale. And he gave her his helmet to barf in during the Eclipse. If anything, the writers are implying that Toke is cannon.

Honestly I think that all the ships will still be around. The shipping war was to prove which one would be canon and now that this war is over there is always imagination. I ship Kataang, George, and Maiko personally, but over time, I learned that the other ships had there reasons why they were started. Like Zutara for example: Fan girls imagine themselves as Katara and being with Zuko and vice versa. I'm pretty sure there's more to it than that, but to make my point, I've come to respect all of them(well, maybe not every one of them, like crackships which are funny). Besides, where's the fun in it all if you can't mix relationships for comedy or story.

Bonding =/= romance. For more relationship discussion come here.
