Fueled by concern and dealing with the god's total silence, Tristan, accompanied by Tomás and Arsene, embarks on a mission to find Thalia. Advancing out of the camp, they navigate the shadows, grappling with their fears and uncertainties while sharing moments of camaraderie, humor, and the revelation of their individual strengths.
