After collaborating with Amity in assisting and later defeating Kikimora with her own personal business, Amity shows Luz her phone, which she left behind at school, playing a video Luz recorded for Camila. Luz finally explains her situation to her mother, and they promise to maintain themselves together throughout the journey. Luz resolves to meet with Philip personally, after learning from Eda that time-traveling puddles exist. With the help of Lilith, they travel to Philip's era through a puddle. However, they end up having to defeat Philip after he betrays them, leaving Luz guilty of having been blinded by her admiration for him. Luz agrees to help Amity in a competition, but Amity notices Luz is acting differently. Luz reveals to Amity that her father died a long time ago, and on his death anniversary, she spends the day with her mother. However, she will be unable to accompany Camila this year. They send flowers tied to a balloon into the night sky, in the hopes that they will reach the Human Realm. Luz and Hunter end up trapped inside Belos' mind. There, Luz discovers not just the whole truth about Belos, but also discovering his true identity as Philip Wittebane. After being saved by Eda and King, Hunter is left shaken at what he has discovered and tearfully runs away while Luz feels guilty as she realizes that all the events that have transpired were indirectly caused by her. She tells Eda, Hooty, and King about the things she saw on Belos' mind, but does not mention his real name or reveal her actions. Luz, King, and Hooty travel to a village inhabited by beings similar to King, who call themselves the Titan Trappers. Luz and Hooty learn from talking with the elder of the village, Bill, that King is actually the son of the original Titan. Bill orders the village to sacrifice him, but Luz and Hooty save him, destroying the entrance portal as they escape.
