After restoring everyone's memories, Cate experiences a seizure and unknowingly traps Marie, Jordan, and Andre within her mind. Cate's imaginary friend, "Soldier Boyfriend", warns them to escape before she enters a vegetative state. While exploring Cate's memories, Luke exposes Andre for making Cate cheat on him while he was alive. As the group flee, they enter one of Jordan's memories, wherein they saved Brink from an enraged Luke and earned a job as his teaching assistant. Upon seeing a memory of the Riordans being experimented on in the Woods and Cate forcing Luke to forget what happened, the group enter Marie's memory of her parents' deaths, during which Annabeth accused her of willfully killing them. Eventually, they confront Cate and convince her to take responsibility for her actions, causing them to awaken. Sam arrives to confront Cate, but Emma talks him down and reveals Shetty used him to augment Luke's powers and is experimenting on other children. Meanwhile, Cardosa tests his virus on an electrokinetic girl named Betsy, which causes her to grow sick and weakens her powers before killing her. Initially shocked, Shetty orders him to make the virus contagious.
