Prince Zuko:
There's one technique you need to know before facing my Father. How to redirect lightning. If you let the energy in your own body flow, [He stretches his left arm out and the fingers on his right hand touch the fingers on his left hand and swiftly traces a path down his arm, shoulder, stomach and back out the other side]... the lightning will follow it. [His left hand touches his right, they are parallel to each other] You turn your opponent's energy against them.

Aang:
That's like waterbending.

Prince Zuko:
Exactly. My Uncle invented this technique himself by studying waterbenders.
