Distant memories
An old dream rammed into her mind and she pulled away from Aang violently. It filled her mind and left her with a headache and screaming. Everyone stopped what they were doing, and rushed over to her. "No... No!" she cried and bent down to a kneeling position, clutching her hair, while Aang stood by, totally helpless. "Aang! What did you do to my sister?!" Sokka screamed, but was drowned out by a heart-breaking screech from Katara. He noticed a pool of water beneath Katara's head, and realised she was crying, but none of them could do anything. The next thing they knew, she was lying on the ground, unconscious. Aang crouched next to her, stroking her hair, wondering if he should bring her back to her room. "Bring her back to her room, Aang, and get her some water." The airbender complied without hesitation.
When Katara woke up, the first thing she saw was a blue arrow, and then two gray orbs staring at her. She realised it was Aang, and sat up, only to be pushed down gently. He asked, "Katara, what happened just now?" All at once, her mind regained the memories of what happened. She screamed, a short, piercing one this time, and fell off her bed, desperate to get away from Aang as much as possible. "Stay away from me if you know what's good for you." she said with a trembling voice, tears rolling down her tanned skin. And then she broke down. Aang was confused, but he still walked over to her and stroked her gently. She flinched at his touch and attempted to run away. If she weren't so weak then, she would have succeeded. And because she was so weak, Aang managed to get her back onto her bed and get her to sleep. He went outside to tell the others.
Katara laid on the bed, feeling very guilty that he was treating her with so much love and care. She closed her eyes and pretended to be asleep, if only so he'll leave her alone. She opened her eyes once he left her room, and stared at the ceiling, thinking of the last time the same thing happened.
-Flashback-
They were on the balcony of the play house on ember island. Aang was leaning closer to her, eyes close. Katara was too busy thinking of her task to notice so. When their lips contacted, a distant memory wove itself into her mind, and she immediately pulled away, shouting, "I said I was confused!"
-end flashback-
What he didn't know was the reason she kept pulling away. She thought back to her dream, that night when she found Aang in the iceberg.
-Flashback-
It was very dark, she could not see anything. Then she did. A solitary glow in the distance. It was moving closer. Closer to her own glow. Then she left her body and watched as the two orbs of light collided, and one died out. The next thing she knew, she was in a garden. Her mother was standing in front of her. Her mother opened her mouth, and said, "my dear child, you have a mission to fulfill. You must destroy the Avatar. You need to first master all 4 elements." "But mum, I don't want to destroy the Avatar! He brings hope to the world! Also, why would I want to destroy an innocent human? And how am I supposed to master 4 elements in less than 6 years when even the Avatar takes about 2 years to master just one! And I have to find the Avatar, and he has been missing for a hundred years now, do you think it's so easy for me to just stumble upon him suddenly? I will not do it!"
-end flashback-
But in the end, she had mastered all 4 elements. Now she just had to destroy Aang, and she would have fulfilled her destiny! Simple, if only she had not fallen in love with him. Now she just feels more conflicted. Why, oh why did there have to be such a task for her to complete? She absent-mindedly played with a cyclone.
Aang came in again, to discover her playing with the air. She was twirling her fingers around, making a mini cyclone. He felt his jaw drop and let out a squeak, which she heard and quickly dropped her fingers, letting the cyclone settle back into calm air. "You... But... How... What... Katara! What were you doing?!" he nearly screamed. "What did you see, Aang? Was I doing something weird? It must be your imagination." she dismissed it, but her heart was thumping in her chest, threatening to jump out of her mouth. Aang gave her a skeptical look, and let the subject drop. "Go to sleep. You need to recover from the shock." She nodded and fell back into bed, letting him put her blankets on.
