"Do you really think Angel's going to be able to fix this when he returns?" Katara questioned, brow furrowed slightly as she gazed up at Zuko. "I know he's strong and brave, but it seems as though we're all expecting things to just get better when he gets back. What if they don't?"
Not that she thought the sun wouldn't eventually return. She meant what she said when she told Zuko they would get it back. Her only issue was the complete faith everyone seemed to be placing upon Angel's return when, in actuality, Katara couldn't see the vampire making that much of a difference. Not unless he knew who was responsible for this and how to fix it, which she highly doubted.
