[The Rise of House Ackerman]

I don't know if anyone realized this, but the whole chapter ends in "The power cannot be used by Eren, so the world will never be saved from the titans."

We're set to believe that this is true and Eren cannot use the power to its extent. However, that's not what Rod Reiss is saying. He is telling Historia that the powers can't be used at all. Now, if any of you recall, Eren was able to control the titans regardless of this. So, in other words, he can use this titan ability.

Rod Reiss doesn't know this. Historia probably hasn't processed it. But if you think about it, then it's clear. Eren is part of the Reiss family.

Now this leads me to ask the question: Did Grisha know this? He must have been part of a movement that wanted the Reiss family to deliver the humans from the titans. As we read, it's clear that for 100 years the Reiss family had the ability but purposely did not use it. Perhaps Grisha wanted this to happen, and so he stole the titan power from the Reiss family.

But wait, if Eren is a member of the Reiss family, wouldn't Grisha? Clearly not. Their last name is "Yeager." But what's the last name of Eren's mother? It was never explained. Therefore, Eren's mom must have been part of the Reiss family bloodline (hence the resemblance of that the family seems to share). Did no one else think that Historia's sister looked like Eren's mom? This must be the case.
