The Ed in the Iceberg

The first episode of Book 1: Water.

Plot
Two siblings, Nazz and Eddy, are out fishing in a small canoe. Nazz, a Waterbender, practices Waterbending, as Eddy prepares to spear a fish. Nazz bends the water around a fish to lift it above the canoe; Eddy penetrates the water with the back of his spear, causing the fish to fall back into the water and wetting him. Edd gets angry and scolds Katara, saying that if he had "wierd powers" he would have kept his wierdness to himself. The sea currents pick up speed, Sokka tries to steer the boat to avoid being collided with the small chunks of floating ice, while Katara gives directions but eventually the boat is crushed between two icebergs, leaving Sokka and Katara stranded in the middle of the sea on a floating chunk of ice. Sokka blames Katara for the mess, which causes her to lose her temper and scold Sokka. Sokka and KataraAs Katara rages, she ends up violently Waterbending without realizing it; soon, she cracks and shatters an iceberg, revealing a giant glowing orb of ice. Seeing the form of a person inside the ice, Katara thinks the person needs help, and begins chopping away at it with Sokka's club, while Sokka warns her not to as they don't know who the person is. The ice breaks, and releases a bright column of light into the sky.

Prince Kevin, a Fire Nation teenager who has been hunting the Avatar for two years, sees the bright light from his ship. With him is his Uncle Iroh. Zuko orders his crew to head toward the light, insisting that the light came from the Avatar.

After Katara breaks through the ice, she finds the person is a young boy with strange arrow-like marks on his head and hands. Sokka is skeptical, and points his spear at the boy. The boy falls out and into Katara's arms. She lays him down and tries to help him. Sokka pokes the boy in the head with the blunt side of his spear, still skeptical, but Katara shoos him away.

The mysterious boy drowsily opens his eyes to see Katara staring at him with deep blue eyes. He quickly becomes fully alert, cheerfully asking Katara if she wants to go Penguin Sledding with him. The boy introduces himself as Ed (Avatar) and sneezes, sending him high into the air, but he slowly drifts back down again unharmed. Katara realizes that he must be an Airbender.
