Zuko was just given orders from commander Zhao, he just lost his entire crew except you and Uncle Iroh. You and him were on the ship alone, and Zuko ran out of his room.

"I heard something. Come with me to check the ship."

You follow behind him and the deck is empty but you hear shuffling. He turns to look out the window and sees the pirate's Lizard Parrot.

"..Pirates."

Then, a explosion that blasts them out of the ship, throwing them into the water.
