The sequel series' second season reveals that Avatar Aang apparently treated Tenzin as his favorite child, due to his son's Airbender status; Kya and Bumi mentioned to Tenzin that Aang always took Tenzin on vacations with him, but never them. Aang's Air Acolytes also were unaware that Aang had two other children besides Tenzin. Tenzin himself insists that Aang loved all his children equally, but that Aang took more precedence in raising him since Tenzin would have to take care of future generations of airbenders. Aang himself later appears, along with Roku, Kyoshi and Kuruk, before Korra in a vision and encourages her to learn the origins of Wan (the first Avatar) and Raava. Aang, or possibly a vision of him, later appears in the Spirit World, encouraging Tenzin to move past the enormous legacy of being Aang's son and find his own path. Korra's connection to Aang and the other preceding Avatars is severed when Vaatu extracts and subsequently kills Raava, the divine Avatar Spirit entity within her. Even though Raava is reborn and fused again with Korra, she discovers, to her dismay, that her spiritual connection to Aang and all past Avatars is gone forever.
