However, they are caught by two Public Safety soldiers. Not wanting to trouble his parents, Grisha took a beating for himself and Fay by Kruger while his partner Gross offers to take Fay home. But Fay's bloodied corpse is found the next day with Grisha knowing Gross murdered his sister. Gross lies to Fay's parents, claiming he took her back to the Liberio Internment Zone. Fay's father tells Grisha their people's history and the Marley nation's justifiable prejudice towards them, accepting the officer's lie. In his adult years, Grisha joins the Eldian Restoration movement after learning the truth of Fay's death from an Eldian named Grice. The movement supported by the secret informant "Owl", Grisha learns the Eldians' true history while eventually marrying Dina Fritz, the last remaining Eldian with royal blood on the mainland, and they have a son Zeke who appears with them in a photograph. When Marley begins its Warrior program to keep up with rival nations over natural resources, Grisha's attempt to raise Zeke as an infiltrator resolves in his son turning the Restorationists to the authorities. Grisha and his fellow Restorationists are then taken by boat to the perimeter wall of Paradis Island for exile as mindless Pure Titans once injected with Titan spinal fluid. Grisha recognizes Kruger and Gross among the squad as Gross kicks Grice off the wall and gives him a head start before turning the others into Titans, including Dina who becomes the Titan that will eventually devour Eren's mother. Gross admits killing Fay and was about to kick Grisha over the wall, only to be suddenly shoved by Kruger and eaten by a Titan. Kruger reveals himself to both the Owl and a Titan shifter as he transforms into the Attack Titan and annihilates the rest of the Public Safety soldiers.
