Complete story — includes the ending
After leaving the desert, the group fortuitously meets Suki and attempts to lead a pregnant woman named Ying and her family through the Serpent's Pass, a dangerous route to the outskirts of Ba Sing Se. They are attacked by a Fire Nation ship and narrowly escape. Suki and Sokka attempt to rekindle their relationship, but Sokka is hesitant and overprotective due to being unable to save Yue. Meanwhile, Iroh and Zuko, assuming new identities as Earth Kingdom refugees, are also on their way to start a new life in the Earth Kingdom capital. They encounter Jet and his fellow Freedom Fighters Smellerbee and Longshot, with whom Zuko starts to bond. Aang and the group are attacked again, this time by the route's namesake. He and Katara defeat the serpent and the group finally lays eyes on the great wall of Ba Sing Se. Ying goes into labor and delivers her daughter, named Hope after inspiration from Aang. Sokka and Suki share their first kiss, while Aang confesses to Katara how the happiness of Ying's family reminds him how he feels about Appa and her. Aang departs with Momo to find Appa in Ba Sing Se, but is shocked to see that a massive Fire Nation drill is approaching the wall of Ba Sing Se. Note: This is part one of the 44-minute special "The Secret of the Fire Nation" and listed in the DVD as the two-part episode "Journey to Ba Sing Se".
