Early in Azula's search, the captain gave the Crown Princess a hint that the ship cannot enter the port because of the tides. She asked if the tides commanded the ship, to which he replied he did not understand. Azula made it quite clear that she was the one in charge of the ship, but in fact he was the sole command of the ship. Under the threat of being thrown overboard, the captain agreed to enter the vessel at the port despite the difficulties.
When Azula successfully tricked Zuko and Iroh, although the latter had been suspicious from the beginning, into the charade that her father wanted them back, it was the captain who blew the secret. He mistakenly said, "Raise the anchors! We're taking the prisoners home", quickly realizing his mistake. Upon hearing themselves referred to as prisoners, Zuko and Iroh immediately realized what was going on, and Azula shot the captain a deadly glare. Zuko easily pushed him out of his way and off the ship so he could reach and fight Azula.
