Is there an atar the Last Airbender episode where Katara gets hurtv?

While Katara does get hurt in several episodes of Avatar: The Last Airbender, there's no one specific episode where she gets injured that stands out as a particularly defining moment.

Here are some examples:

* "The Waterbending Master": She's struck by a waterbending blast from Hama.

* "The Siege of the North, Part 2": She's wounded by an ice attack from the Northern Water Tribe soldiers.

* "The Avatar and the Fire Lord": She's hit by a blast of fire from Azula.

* "The Day of Black Sun": She's injured by Azula's lightning attack, though she's saved by Aang.

Do you remember a specific scene or type of injury that you're trying to recall? If you can provide more details, I might be able to pinpoint the episode you're thinking of.
