Who will marry Zuko in Avatar the Last Airbender?

In the original Avatar: The Last Airbender series, Zuko doesn't marry anyone. While there are hints of potential romance with Katara, their relationship remains platonic.

However, in the sequel series, The Legend of Korra, Zuko does marry Jinora, the airbending daughter of Tenzin (Aang and Katara's son) and Pema. This is only revealed in the very last episode of the series, "The Light in the Dark", as a happy surprise.
