In Republic City, Fire Lord Izumi (April Stewart) and Tenzin refuse to endorse Raiko's proposed offensive against Kuvira even after Bolin and Varrick bring word of her vine weapons research. Spirit vines attack Jinora and others, trapping them in the Spirit World, and Korra's rescue attempt is thwarted by Zaheer's apparition. As she faces him in his prison, he agrees to help her defeat Kuvira and leads Korra into the Spirit World, where Raava helps her release the captives' spirits. Meanwhile, Bolin attempts and fails to make up with Opal, who is set on rescuing her family with Lin.
