Yue's relationships

Arnook


On the day Yue was born her father had a spiritual vision of his daughter; he learned that when she grew to maturity, she would become the reincarnation of the Moon Spirit. Shortly after her parents found out she had a fatal illness, her father would pray to the moon spirit every day and placed her in the Spirit Oasis. The moon spirit placed a bit of her own life force within Yue From then on, she was known as Yue after the moon.

He was gentle and compassionate towards her daughter. As shown by his actions after she was born, he was very spirutal and was wiling to do anything to save his daughter's life. She was always seen by his side when at formal tribal events. Though sometimes their relationship was strained, such as in the case of the arranged marriage, he shows that he always has his daughter's interests at heart when he appoints Sokka as her bodyguard. He of Sokka's close relationship with Yue and wanted him to comfort his daugher. When he is last seen, he is looking up at his daughter, furfilling her destiny as the moon spirit.

Sokka


When Sokka first arrivcedfrom the Sothern Water Tribe, Yue shows affection towards him and smiles. She laughed at his jokes and seemed impressed when he told her that he was the leader from the tribe he came from. When they meet again the next day, they begin to arrange meetings. These included riding on Appa and taking walks together. Sokka and Yue came to realize their love for each other, but she could not bear to continue their meetings because they conflicted so strongly with her duty to her tribe.

Yue eventually said she could not see him anymore because she was already engaged to a young man named Hahn, though in reality it was a political union and she did not love him. She explained that she had feelings for Sokka, but could not abandon her people and their customs. Hahn for her people, to which Sokka replied she was not marrying her people. Both of their feelings persisted, and during Admiral Zhao's siege of the Northern Water Tribe, Sokka was ordered by Arnook to act as Yue's bodyguard. The relationship came to a tragic end when Yue sacrificed her mortal form to give the waterbenders' patron Moon Spirit new life after Admiral Zhao killed the mortal of the Moon Spirit. Her spirit appeared before him shortly after, wearing a long white gown. She whispered, "Goodbye, Sokka. I will always be with you", and the two shared a final kiss before she vanished completely.

Several times following her death, Yue's influence on Sokka returned. While in the Foggy Swamp, Sokka, under the swamp's magical influence, saw a vision of her. The vision of Yue angrily told Sokka that he failed to protect her, perhaps a manifestation of his fear that she truly felt this way. During his time in the Si Wong Desert, Sokka directly referred to the moon as Yue in the intoxicated state brought about by drinking cactus juice.

When Sokka and Suki nearly kissed while crossing the Serpent's Pass, a waning gibbous moon is visible in the background, alluding to Yue's presence, and Sokka's memories of Yue's death prompted him to refuse the kiss, while acting overly protective of Suki. While looking for leads as to disappearances surrounding the full moon, Sokka yelled at Toph when she suggested that the moon spirit might be harming people, saying that the moon spirit "is a gentle, loving lady who rules the skies with compassion and lunar goodness", showing that he still cared deeply for Yue. While with Zuko on the way to the Boiling Rock, Sokka mentioned that "[his] first girlfriend turned into the moon."

Hahn


Sometime prior to Team Avatar's arrival at the Northern Water Tribe, it was arranged that Yue would marry a young, egotistical warrior named Hahn who carved a betrothal necklace for her to mark their engagement. It was revealed that she did not really love Hahn and was marrying "for her people," suggesting it was more of a policitcal marriage instead of a romantic one. Similarily Hahn had more love for her high status than for Yue herself. He boasted once to Sokka that "she comes with the most perks." Though she did not really love him, she remained loyal to their engagement anyway and refused Sokka's first advances.

Aang


Yue aided Aang in entering the Spirit World, by leading him and Katara to the Spirit Oasis. Later, when Aang had been captured by Zuko, she accompanied Katara and Sokka as they tracked the two of them down on Appa.

After Aang was struck down by Azula's lightning during the Coup of Ba Sing Se, the Avatar met Yue in the Spirit World. She informed him of the damage that had taken place to the Avatar Spirit and explained how to return to his body, further instructing him to seek out the past four Avatars while avoiding Koh, the Face Stealer. She later appeared to Aang once more to encourage him not to lose hope and to continue fighting. She then assisted him in his impressive feat of waterbending to get himself to safety, utilizing her powers as the Moon Spirit.

Katara


During the time that they spent together, Yue and Katara got along amicably and became friends. Yue led them to the Spirit Oasis where they worked together in helping Aang reach the Spirit World. Later, when Zuko attacked them Katara used their waterbending to defend them while Yue protected Aang. She accompanied Katara and Sokka as they tracked the two of them down on Appa. Katara would sometimes look towards Yue as the moon spirit, as a reference to her waterbending powers.

Tui
When Yue was born with an unknown illness, her parents prayed for her surrvival and placed her in the Spirit Oasis. She was seriously ill, very weak, and on the brink of death. The Moon Spirit gifted her with part of its own life force, saving her life and turning her hair white as a side effect. Thus, her parents named her Yue, for the moon.

When the Fire Nation invaded, Admiral Zhao killed Tui the moon spirit. Yue realized the only way to save the Moon Spirit was to give up a piece of herself. Yue then made the ultimate choice: to sacrifice her life in order to resurrect Tui. Once this happened, not only did the moon return to its full power, but Yue's physical body disappeared and reformed as Yue's spirit form, making Yue the new Moon Spirit.

By having her life force energy re-bond with Tui, Yue not only reincarnated as Tui's successor, but she also gained the ability to waterbend, a trait she did not carry in life. Her abilities were seen to some extent when she generated a massive wave for Aang to ride on, toward the island where Roku's temple once stood.
