They were both stuck in a cave. This wouldn't have happened because of that water tribe peasant girl.
And in the corner he could hear her crying, and Zuko was pretty sure that it wasn't his fault.
The subject of war came up, and he began to learn more things about a girl he really didn't need to know. But he learned more about her life, and realized how much that she had in common with himself.
They both lost there mothers to the fire nation, and he could begin to understand why she never did like the fire benders at the moment.
Zuko never realized how beautiful caves were, until now.
