For all the time Eren and Historia spend together, the latter actually has a lot in common with another member of the Yeager family – Grisha.
Kodoani.com – WARNING: The following contains spoilers for Attack on Titan Season 4, episode 28“The Dawn of Humanity”
Eren Yeager of the Attack on Titan and Historia Reiss had a complicated history together. Since the former started opening up more in Season 3, the latter started to care about her more as a human and wants her to live her best life. Eren and Historia have become so close since then that many AOT fans attribute the two of them to more than Eren and Mikasa; There are even rumors that Eren is the biological father of the child Historia. Almost like these two, there may be a Yeager with whom Historia shares an even closer connection – Eren’s father, Grisha.
Naturally, Historia also suffered the same grim fate as Grisha Yeager. However, Eren recognizes this ability and seeks to overcome it. The similarities become especially apparent in the final installment of Attack on Titan: The Final Season Part 2.
During a flashback in Episode 28 of The Final Season, “Dawn of Mankind”, Eren talked to Historia about his plans to start Rumble. Historia was naturally against the plan; she’d rather go with the Eldian Army’s plan, which involves becoming a Titan, eating Zeke, giving birth, and, ultimately, being eaten by the aforementioned children. This choice wasn’t in her best interest at all, but at least the rest of the world wouldn’t have to die for it.
On the other hand, Eren opposes history in favor of self-sacrifice. Eren always wanted to make sure she could live for herself, something she definitely couldn’t do with the Legion’s plan. He also mentioned that he doesn’t want to let the cycle of parents being eaten by their children continue. The second point is where the connection to Grisha can be drawn.
At first glance, the idea of ”children eating their parents” seems to go hand in hand with Ymir’s life. She was also fed to her children so that the Founding Titan’s powers were passed on. This tradition was continued through the generations as the Subjects of Ymir became what they are now. However, Eren’s comment might revolve around something a little more personal.
Eren himself was forced to transform into a Titan and eat his biological father. When Eren first realized this, it drove him crazy and left Eren feeling guilty. It is likely that Eren made his remarks about children eating their parents with his own traumatic experience. This would certainly explain why Eren was against the idea of Historia feeding her own baby.
In a sense, Historia and Grisha were both accomplices and victims of Eren’s scheme. Although they both kept Eren’s actual agenda a secret, neither of them really wanted to go along with it. They hated the idea of entrusting a grim fate, but they also realized that Eren’s replacement was far worse. Despite that, the two were surely lured by Eren into following his plan. They both regret their decision to follow Eren, but eventually learn to live with them.
While Historia and Grisha do not suffer the same fate, they most likely have. Ironically, it was Eren who caused and prevented the cycle of connecting the two from repeating. If these two victims of fate somehow meet, they will surely have a lot to talk about together.
