Avatar: Last Airbender - Fire Lady Rin (Fire)

Embarrassment Central

"Water... Earth... Fire... Air..." Katara voices over as the benders demonstrate as she talks. "My grandmother used to tell me stories about the old days, a time of peace when the Avatar kept the balance between the Water Tribes, Earth Kingdom, Fire Nation, and Air Nomads. But that all changed when the Fire Nation attacked." It journeys into the map showing the world and closes in on a bender displaying all the elements. "Only the Avatar mastered all four elements. Only he could stop the ruthless firebenders. But when the world needed him most, he vanished." He disappears from sight. "A hundred years have passed and the Fire Nation is nearing victory in the war. Two years ago, my father and the men of my tribe journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving me and my brother to look after our tribe." It shows the Water Tribe men on their boats and Katara hugging her older brother Sokka holding up a lantern. "Some people believe that the Avatar was never reborn into the Air Nomads and that the cycle is broken, but I haven't lost hope. I still believe that somehow the Avatar will return to save the world."

Embarrassment Central

At the Fire Lord's beach house on Ember Island in the rocks and hills around it, Rin, Aang and Zuko practice their Firebending out in the courtyard with a fountain. 

They Firebend in sync, they take a step forward and throw their arms down, Firebending at the same time. They stretch out their right leg in front of them, Firebending again. They stretch behind them and they push out their left leg out as they Firebend with their arms and put their leg down and exhale, putting their arms in a cooling down position and bow to each other. 

Katara, the twins and Toph watch at the side in their Fire Nation disguises, Zuko cracks his fingers and stretches both arms above his head and walks off while Aang massages his shoulder, Rin jumps and flips into the air continuing her Firebending practice and Aang watches her wanting to be at her level but knew he had to work at it like everyone else. "Doesn't it seem kinda weird that we're hiding from the Fire Lord in his own house?" Katara asks looking around the courtyard with Toph napping next to her.
