“…You should be proud, you taught them well.” -Lin Bei Fong
Clearly, Aang taught everything to Tenzin and taught them to the airbabies ^^
Airbending Slice, Air Scooter, and Air Sphere!
“Fire is the element of power. The people of the Fire Nation have desire and will, and the energy and drive to achieve what they want. Earth is the element of substance. The people of the Earth Kingdom are diverse and strong. They are persistent and enduring. Air is the element of freedom. The Air Nomads detached themselves from worldly concerns, and they found peace and freedom. And apparently they had great senses of humor! Water is the element of change. The people of the Water Tribes are capable of adapting to many things. They have a sense of community and love that holds them together through anything.”
“I… I can airbend? I can airbend!”
The Waterbenders learned how to bend watching the push and pull of the tides. The Earthbenders were taught to shape the earth by the badgermoles. The Airbenders were inspired to soar by the Flying Bison. And the Firebenders learned their bending from the masters, Dragons. Even now, the cycle continues.
