"Good work, but this time widen your stance." Zuko said, trying to teach Aang to firebend.
"Oh, so like this." Aang said lunging forward and shooting a large fireball from his hands.
"Good work, but that is enough training for today though." Zuko told him as they bowed to each other.
Meanwhile…
"So, did Aang ever go see that guru to un-block the seventh chakra?" Katara asked, wondering.
"Yeah, I think." Sokka replied, "He came back from the temple a few days ago."
"There he is!" Katara said happily, "How's training going Aang?"
"Good, he is doing very well." Zuko replied in response to her question.
"I was talking to Aang!" she replied angrily.
"Sorry." Zuko said in a sarcastic tone. Then he thought suddenly, I really shouldn't have said that.
Zuko just backed away a few steps as she quickly turned her head back at him, hoping she wouldn't do anything to him.
Toph, Haru, Teo, and The Duke walked in just in time to see Katara attack Zuko with water. The four and Aang and Sokka just watched as Katara froze him against the wall before he could do anything. As Katara started walking away, making her 'dramatic exit', Toph bent a small rock right in front of her, making the waterbender trip and fall. Everyone tried to hide their chuckles, except for Toph who was laughing her head off.
"You think it is funny?" Katara said infuriated.
"Yeah." Toph said, while still laughing, "But you kinda deserved it after treating Zuko that way. After all, it was just a sarcastic comment."
"Toph is right." Aang said, "You aren't treating Zuko well."
"Aang, he wiped out your people, he took Sokka and my mother away, he..." Katara was cut off by Aang.
"He didn't do any of that, he isn't like the rest of the fire nation, though you treat him no better than you would the firelord."
"Aang, I…" Katara tried to say something before Aang flew off on his glider.
A little later…
Katara finally got off Appa to find Aang meditating. She put her hand on his shoulder.
"Go away Katara." He said.
Katara felt a tear start to go down her cheek, but quickly wiped it off. This was pretty much the first time Aang had been truly mad at her. She sat next to him.
"I'm sorry Aang, I just can't let go of that grudge I hold against Zuko. I couldn't stand it if he betrayed us again, if he hurt any of us, if he hurt y…someone I care about" Katara said, blushing a little. She knew that if anything happened to Aang, she wouldn't be able to live with herself.
"Aang, talk to me please, I want to help you. I don't want you to be mad at me." She said, pleading for his forgiveness.
"I'm not mad at you, I'm mad at myself. I let the world down at Ba Sing Se, then I failed the world on the Day of Black Sun, now I'm failing to keep this group together, and if I can't keep the group together and don't learn firebending, then I won't be able to beat the firelord and the world will be conquered by the fire nation and it will be all my fault."
"Aang, don't talk like that, you know we will never abandon you, and you WILL defeat the firelord next time." The waterbender said. She couldn't stand to see Aang this depressed. Seeing that Aang wouldn't talk to her anymore she left to the others.
Once she got there she wouldn't talk with anyone, not even her brother. She just went straight to bed.
Aang was back around an hour later.
"Hey, where is Katara?" He asked Sokka.
"She went to bed, why? Is there something wrong?" Sokka replied.
"No, everything is fine." Aang lied, forgetting that Toph could tell if he was lying or not.
She frowned, and followed him into the chamber of the air temple he was going to be sleeping in.
"Ok, what is going on with you and Katara?" She asked, making Aang jump so high he almost hit his head on the ceiling.
"N…nothing." He said nervously.
"Ugh, are you forgetting I can tell if you are lying or not." She said.
"Oh right, why do you have to be able to tell if people are lying?" Aang said jokingly.
"Tell me what's going on betwe…wait, you like Katara." She said, already knowing the fact, but saying it just to see if Aang would have some weird reaction to her words that she would be amused by.
"Alright, I like Katara, ok? But how did you know?" He asked.
It's pretty obvious, you don't need to be able to sense people's heartbeats to see that, be glad that Sokka is an idiot." Toph said
"Please don't tell anyone about this, alright?" Aang said.
"Ok, but if I were you, I would tell her soon." The blind girl said. And without another word, she walked out of the room.
She wanted to see if she could get them together, not for them, but for the hilarious reaction that Sokka would give if he caught them kissin', so she walked to Katara's room…
As soon as Toph walked up to Katara, she looked at the earthbender, with a tear in her eye.
"I've hurt him. I was worrying so much about Zuko hurting him, that I hurt him instead." She said sadly.
"Wow." Toph said, "I think there is something different going on in him, and it is pretty obvious."
"What's that?" Katara asked curiously.
"Remember when we were saying goodbye to Aang before he went to find the firelord?" Toph asked.
"Where are you going with this?" Katara asked suspiciously.
"I think you know." Toph said making kissing noises.
"How did you know about that?!" She asked with some anger in her voice.
"Let's just say, I'm getting better with seeing with metal. You know that you liked it too. You know you can't avoid talking with twinkletoes about it forever."
Without another word, Toph was out of there. Her plan was going perfectly.
