Suspicion
Katara snuck out of the house and out to a deserted area which no one knew of, and practised her bending. She first meditated, feeling for any vibrations nearby. When the area was confirmed clear, she began, practising waterbending first. She stayed practising that, just in case anyone had been following her. Finally, she ran out of techniques to work on, and began to do some earthbending, in small amounts. All the time, she felt someone had been watching her, but dismissed the thought when no one jumped out at her even when she finished earthbending training. Eventually, she was done with all exercises and headed back home, still a little on her toes, expecting someone to suddenly jump out of the shadows.
Katara managed to reach home to everyone eating breakfast. They all muttered a sleepy greeting, still too tired to wonder what she had been doing outside. Only Aang was wide awake, and jumped out of his chair at the sight of her return, pulling out her chair and gesturing for her to sit down. Katara sat down and he went to the kitchen to get her food. Even though his actions were as usual, his face said otherwise. His smile never reached his eyes; they stayed a lifeless gray. After breakfast, Aang took Katara by her wrists and brought her outside to the garden. "Where are they going?" Sokka asked Toph, who merely shrugged. They ignored that and continued to dwell at the breakfast table with the others.
Once outside, Aang grabbed a rock when Katara wasn't looking, letting her go ahead. Aware that he wasn't beside her anymore, Katara turned around to see a rock flying towards her at breakneck speed. Without any thought, she stopped it with a wave of her hands, then immediately realising her mistake. She saw Aang's jaw drop, and then quickly recover to ask, "Katara, why didn't you tell me?" "About what?" Katara whispered, looking very sorry. "That you could bend all four elements, just like me!" "Well... Aang, I'm sorry, but what was I supposed to tell you? That I was an Avatar assassin?" she quickly covered her mouth, realising what she said in a moment's rage. Tears quickly escaped her eyes as she ran away, aided by the wind, and Aang slumped down the tree, still not believing what he had heard.
She was not seen for the rest of the day, and he was seen in such a depressed state Sokka would rather not see him at all. No one knew what had truly happened, except Toph, who just so happened to sense them outside at that moment. She went to see Aang, who had just recently locked himself up in his room, and found him sitting on his bed, talking to himself, "So she only came with me to get close with the Avatar, so that she could kill me in my sleep? But then why didn't she kill me straight away? There were definitely many different chances! Or maybe she was trying to break me down so I'd let my guard down! No... I know!" "Aang!" Toph shouted, and felt him jump. "Toph! I didn't realise you were there! What are you doing here, anyways?" "I came to see if you were ok, and apparently you're not. Look, I know what happened just now, and I feel sorry for you. I mean, how many unlucky guys fall in love with a girl who was out to kill him... Sorry, I wasn't thinking." Toph bit her lip in embarrassment, and also to keep herself from spouting more insensitive things. "Well, think about it. Katara was at every training session that you had since you began learning all the other elements, so that's where she picked them up. And she has watched you in airbending action so many times she can repeat the movements in her sleep! Plus she had the gift to learn them, so, there you have it!" Toph reasoned with Aang. "I... Didn't know... Anyways why does she want to murder me?" "Now that I don't know, but I think you should find her and talk it out without any shouting, screaming, bending, and certainly no accusations. Wow... Where did I get that from?" Toph wondered, amused, but he had already run off in search of that girl who had broke his heart.
Of course, she was really hard to find. The moment he thought he had any lead on her whereabouts, she just disappears into thin air. Furthermore, he realised she had taken his glider, which gave her an edge over long distances. It was like she was avoiding him on purpose. But then again, she was!
