Heir of Revan wrote: Truth be told, I'm not sure what to make of Eren and Historia's relationship. True, they're related by distant ancsetor (Grisha, Eren's father, being married first to Dina Fritz, who's from the same family lineage as the First King, and Historia due to her being desended from the First King and shit) but still, if he wants full control of the coordinate, he'll have to eat her. Why? Well, I'm pretty sure if she eats him, she'll end up like her sister and ancsetors before her. Isayama confirmed that he made a mistake when he had Eren think that he may have to "eat" Historia or any royal turned into a titan in order to use the Founding Titan's power. He was really supposed to think that he may have to "touch" Historia or any royal turned titan to use the Founding Titan.

If anything, I wouldn't be surprised if Zeke were to play a role like that instead.

I'm not even sure we're supposed to know for sure if the Fritz and Reiss are truly one and the same. I'll wait until we get full confirmation just in case they're actually not. We still have yet to even see how the Reiss replaced the Fritz.
