Tenzin was with his father, Avatar Aang, learning air bending. Aang also was too sad and burdened to tell his son they are the only air benders in the whole world, so he kept that a secret from Tenzin, even everything that had to do with the extinction of their people, the sky bison, and flying lemurs.

"Tenzin I want you to move gracefully through these gates as they spin, without touching them at all." Says Aang. "And how is this supposed to help me, Daddy?" Asks Tenzin. "Air bending is all about detachment from the world, but not love, because that is something to hold on to, my son," Aang says smiling holding the parenting finger up. "And it's also about freedom, and being and having spiritual connections." Says Aang. "You can do the gates when you are ready, but for now, let's work on forms, angles, and movements." Says Aang.

Aang helped Tenzin work on his forms.
