Agony of a Witch

Lilith makes another attempt at capturing Eda, but is thwarted by Hooty. Luz discovers that Eda's curse has been worsening, requiring increasingly more elixir to restrain. At school, Luz learns that they are taking a field trip to the Emperor's castle. She decides to go after learning the castle holds powerful magic relics, including a healing hat that might be able to cure Eda. While on the tour, Luz sneaks off, seeing Lilith being threatened by Emperor Belos with banishment from the Emperor's Coven if she fails to capture Eda. Willow and Gus learn of Luz's plan and help her break into the relics room. They are sensed by Belos and found by Lilith, who holds Luz hostage to lure out Eda. Eda and Lilith have a fight outside the castle, during which Lilith accidentally reveals that she was the one who cursed Eda. With Luz's life on the line, Eda uses up her magic, causing her to transform fully into her owl beast form. Lilith takes Eda away to Belos before telling Luz to return to her own world. A defeated Luz returns to the Owl House and breaks down in tears as King and Hooty comfort her. (Source: Wikipedia)
