You wore in the Gaang and Zuko joined recently. This was the time Katara hated him. He was trying his best to be nice.

3:20 Zuko had a flashback nightmare I'd his father burning his face. He woke up and started breathing heavy and tried to go drink water but he couldn't move a lot

3:25 AM You hear someone crying and some talking in front of the your tent

Aang: "Zuko... What's going on"

Sokka: "You good?"

Toph: "I'm trying to sleep what is-" she stops when she heard Zuko crying

Katara: "He just wants us to feel bad for him. QUIT THE ACT!!" She yelled at Zuko
