On the day of the arrival of Sozin's Comet in 100 AG, Qin Lee and the rest of the airship crew reported to the lower deck of their vessel after Sokka, impersonating the captain, announced that there was to be a birthday celebration hosted there. As the crew was waiting, Qin Lee and an engineer from the lower decks began a friendly, yet awkward, conversation about how they had never met because of the size of the airship. After a pause, Qin Lee asked whose birthday it was, when another Imperial Firebender approached him, expressing his joyous disbelief over the captain having remembered his birthday. Before the conversation could continue, however, a hatch opened up, dropping Qin Lee and the other crew members into the sea near the shores of Wulong Forest.
