So, in this chapter, I'm finishing up the parts that were already in the show, and then the story will really start to develop ;)
Chapter 4: The Beginning of the End
Yakone bloodbended Toph over to him, and had her unlock his handcuffs. They fell to the ground. Yakone raised his hands up, over his head, and the entire everyone in the court room collapsed, except for Aang.
"What's happening?!" Korra shouted. She tried to run up and help but Aang's spirit stopped her.
"You cannot change the past young avatar." He told her. Korra stopped, and continued to watch.
Yakone turned around to Aang, still reaching out, trying to reach him. Yakone raised his hand, and Aang rose up with it. He struggled, but could not get out of the bloodbender's grip.
"Yakone" He said. "You won't get away with this!" Yakone laughed.
"Republic City is mine avatar! I'll be back one day to claim it!" Yakone swished his arm behind him, then in front of him, throwing the avatar onto the stairs. Yakone took off, and ran out of the room.
"We have to go after him!" Korra insisted. She tried to follow Yakone out of the room but Aang grabbed her wrist.
"Korra, you cannot change the past. This has already happened, you can do nothing to change these events." Aang's spirit told her. Korra sighed.
"Now follow me." Aang's spirit said, as he led Korra out of the room.
They walked outside, to see Yakone in a carriage, whipping an ostrich-horse, and fleeing Republic City Hall.
"No! He's getting away!" Korra cried.
"Just wait." Aang's spirit said with a smirk.
Suddenly, Aang burst through the doors of Republic City Hall on an air ball. He flew over Yakone, and cut the ostrich-horse from the carriage. The carriage fell on its side, then skidded to a stop. Aang airbent around the wreckage. He seemed to be wondering where Yakone was. Suddenly, Yakone burst from the wreckage, Aang gasped and tried to run, but it was too late. Yakone raised his arms and Aang tumbled down.
"No!" Korra shouted.
Yakone jumped off the wreckage, and landed in front of Aang. Aang looked up.
"This time I'm gonna put you to sleep for good!" Yakone pulled on his shirt collar, and pointed his hands at the avatar, almost looking like he was gripping him. Aang's head jerked down. Yakone raised his arms, rising the avatar along with them. He bent Aang's arms and legs the wrong way, twisting the avatar's wrist and bending his head back. Aang screamed in pain. His head turned slightly, then, Aang's eyes glowed, and he escaped Yakone's bloodbending grip. Air swirled all around the avatar. Aang jumped down to the ground, and encased Yakone in earth. Aang reached forward, and touched his hands to Yakone's forehead and chest.
"I'm taking your bending away, for good!" Aang said. Yakone tried to move away, but was immobile from the earth the avatar had covered him with. Aang's eyes and tattoos glowed, and Yakone gasped. Aang stepped away, his tattoos and eyes losing their white glow. Yakone's head fell forward.
"It's over" Aang said, relieved.
Korra stared in awe. Aang's voice snapped her back to the "present."
"Follow me, Korra." Aang's spirit said. He led them back to Appa in the dirt parking lot.
"Okay, that was pretty awesome but, what does this have to do with Amon?" Korra asked him as they both climbed on Appa.
"You will see soon." Aang's spirit said, as they took off.
Sorry this chapter was so short but I had a REALLY hard time thinking on how to continue this so I'll just wait till the next chapter ;)
