While Korra is struggling with PTSD by the metal poison Zaheer injected in her, she sets off on a journey to try to connect with Raava. Amidst all of this, Tenzin and the others realize that Korra has gone missing after 6 months.
Korra is struggling to recover from her encounter with Zaheer. During her recovery, she continues to have painful memories of the Red Lotus destroying her physically and emotionally. Korra immediately gives up her role as Avatar by donning earth kingdom clothes and cutting her hair short to prevent anyone from identifying her. During her journey, Korra tries to reconnect with Raava and she encounters a familiar face who might be able to help her.—dawsonpersi
