Deep within the Reiss family's crystalline cavern, the horrifying truth behind Eren's power is violently unearthed. As Rod Reiss pressures Historia to devour him, Eren is flooded with fragmented memories that are not his own, recognizing the cavern as if he's "been here before." These visions reveal the previous wielder of the power, Frieda Reiss, before culminating in a shocking flashback from a Titan's point of view: Grisha Yeager, having stolen the Founding Titan from Frieda, injected Eren with a serum and allowed his own son to devour him, passing on the power through an act of unknowing patricide.
