Hallucinations or The Truth?

"Well look who finally showed up!What have you been doing, planning to betray us again?!", Katara said. Zuko, strangely, said nothing. Ever since Zuko joined their group, Katara was trying to find a good reason to kick him out. As Katara passed around Dinner, Sokka noticed something wrong. "Um, Zuko, are you okay?"he asked. "You do kinda look pale." Aang said. Zuko indeed looked pale. He looked up at them & said, "I'm okay guys. You don't have to wor-". He passed out in the middle of his sentence. "ZUKO!" everyone, but Katara, yelled. Aang tried walking up to him but was blocked off by Katara. "Don't go to him Aang, he's probably just faking it." she said. "He's not faking it, Sugar Queen! He really passed out!" Toph said. Aang went pass Katara & felt Zuko's forehead. The minute his hand made contact with Zuko's forehead, he pulled it back really fast. " He has a really high fever!" Aang said.
