The truth suddenly started to sink in. Katara was on her way back home, where she would find her family one member less.
Reality is merciless.
She had minimum sleep the previous night. Not only because she was on a small ship that struggled to keep head above water with the growing waves, which made her feel extremely clausterphobic. But because she had this recurring nightmare where she was the one who killed her father. She was the one who was responsible for him falling to the ground, screaming in agony, blood seeping through his clothes. Sokka running up to her, tears coming down his face, screaming,
" I hate you. How could you do this to your own father. Why Katara? Why? "
Guilty conscience. She thought.
Dreams are formed of what you really think and feel. You know that it's all your fault.
She managed to silence her mind, but couldn't fall back asleep. So she spent the rest of the night working on the syllabus for when she returns back to the school. That's if she returns. She doesn't know whether she will be able to leave her family again. Maybe she'll stay with her grandmother this time. Make sure that if there is a recurrence of recent events, she'll be close and can start helping immediately. Protect the only parent that she has left.
Stupid. That's what I was. It was a stupid decision to leave. And to what? To fulfill my dreams of becoming a waterbending master, only to teach children who weren't lucky enough to live near a great mass water ,but had the talent? More like little brats who rely more on something that they were born with, and of course their parent's wallets, than hard work.
To pour her heart into her job only to have it thrown back in her face, surely wasn't what she had hoped for when she decided to join the waterbending school in Ba Sing Se.
I wonder whether any of the other members of the Gang regret their life choices? Does Sokka regret following Aang? Does he also blame himself for leaving Dad?
A few years ago when Aang defeated The Fire Lord and peace was brought back to the nations, everyone more or less went their separate ways.
Maybe this will be the oppertunity to get them together.
