Katara stared at Zuko for a moment. Blinking rather owlishly, she continued to just stare at him for a minute longer, waiting for some sort of reaction that, she soon realized, was never going to come. Growling in frustration, the waterbender suddenly slammed her hands on the table and surged to her feet.
"Okay," she said firmly, eyes narrowed and lips pressed into a thin line as she pinned him with a hard look. "You need to snap out of this, Zuko. I realize it isn't easy without the sun, but you can't just keep acting so... blah about everything! There's an entire city of people who need help and you're one of the ones who are supposed to be helping them! You can't do that acting like this!"
