Following Kai's capture, the Dai Li sergeant threw the young airbender into a prison cell underneath the Earth Queen's Temple and welcomed him to the army's first airbending regiment along with the other conscripts in the cell. That night, the Dai Li sergeant and two other Dai Li agents attempted to stop Kai from escaping with Bolin, Mako, and Jinora, stating that abandoning the Earth Queen's army was an act of treason punishable by death. During the altercation that followed, he used a rock glove to grab Jinora, prompting Kai to incapacitate him with a strong gust of wind.
