Now I'm pretty sure Iroh is Zuko's grandson because his daughter is the current Firelord. The whole equalist movement was pointless because Amon aka Noatak was a waterbender, so if he took everyone's bending away, he would be supreme overlord. He even took his own brother's bending away. The only good thing that came out of this is that Mako and Korra got into a relationship. At first I thought it would be Korra and Bolin but nope.
"The true mind can weather all the lies and illusions without being lost. The true heart can tough the poison of hatred without being harmed. Since beginning-less time, darkness thrives in the void but always yields to purifying light."

Carefully watch your thoughts for they become your words.
Manage and watch your words, for they will become your actions.
Consider and judge your actions, for they have become your habits. Acknowledge and watch your habits, for they shall become your values. Understand and embrace your values, for they become your destiny.”
Humankind cannot gain anything without first giving something in return. To obtain, something of equal value must be lost.
