"I could never destroy this city!" Saido cried at the voice.
'It is your fate, though. You will do as you had promised,' the voice seethed.
"Promised?"
'Do you not remember the fire?' Saido felt the heat of flames lapping at her feet and she looked down to find the old wood of a house she had long forgotten. 'Then again, you were so young when it happened.' She looked up and saw the scorched planks of wood lying over two motionless bodies. One of them, a young girl, began to move. "Help, somebody! Mother?" the girl cried out. Saido gasped as she realized the little girl was her.
The fire was spreading quickly and as it approached the girl, it stopped. Saido couldn't hear what the little girl said, but the fire swarmed her once she finished. Rather than burning little Saido, the fire seemed to melt into her skin; her body glowed brightly for a few moments and then she appeared unharmed. "What? How?" Saido gasped.
The vision disappeared and she was in her room in the air temple again. 'That was the night in which I saved you from the brink of death,' the voice said soothingly. 'Your ability to bend fire is because of me. Your water bending soul and my fire spirit is what allows you to bend the two elements.'
"But what – what did you mean about my promise? What promise?" Saido questioned, her voice cracked with fear.
'I saved you because you promised to do whatever was required to let you live. Now that we are here, you will destroy the avatar and Republic City.'
"And if I don't comply with your requests?" she croaked.
'If you fail, then my fire will destroy you.'
Tears welled up in Saido's eyes and fear gripped at her heart. She was trying to prove to the others that she was a good person, not a threat. The presence of the fire diminished, but she knew it was still there. Saido lay down on her bed and hugged her knees to her chest. She sobbed as the memory of the fire replayed in her mind.
