Attack on Titan season 3 episode 7 Wish
Levi's squad burst into the underground chamber and force the Interior Police into falling back to their second defensive position. Meanwhile, Rod explains to Historia that the cavern and city walls were built a century ago by their ancestor who used the Founding Titan's power to wipe the memories of all but a few immune bloodlines. Generations later, Frieda inherited the Founding Titan and the memories of their world before the walls. Rod explains that Frieda metaphysically lives on within the Founding Titan, with Historia realizing that she must become a Titan and eat Eren to gain the Founding Titan and see her sister again. When Kenny learns that only those of the Reiss bloodline can use the Founding Titan's power, he angrily betrays Rod by giving Eren a fighting chance to defend himself. Historia was about to inject herself with a Titan serum syringe when she realizes Eren is too guilt-ridden over deaths resulting from his father's actions to resist, pleading her to eliminate all the other Titans in his stead. Historia then realizes that Rod's true intent is restoring his family's power, revealing that the will of the first king to preserve the status quo will consume her like it did with Frieda and those before her. Historia refuses to go through with it, breaking the syringe on the ground while freeing Eren. But a desperate Rod is forced to lick up some of the serum and transform into a Titan himself and personally eat Eren.
