In his new life inside the Walls, it saw him living by the laws of the land until a family tragedy made him resent the way of the world and rebel, subsequently using his own son as a pawn in the struggle, only for it to turn on him and cost him his life.
Actually, it looks like Grisha didn't learn about his wife's death until
after he killed most of the Reis.
In fact, the timeline escapes me a bit, there. Did he do that because Wall Maria had fallen? That would probably explain his actions (as well as the very fact the Reis were having a secret reunion in their very own hidden basement at the time), but the instructor's flashback makes it look like the instructor learned about the fall just
moments before meeting a post-murder Grisha, so it feels a bit weird overall...
I also wonder what's going on with the Fritz and the Reis. Up until now, we were told the Fritz were just stand-ins and the Reis were the true royal family, but now, it's
the Fritz who were the royal family and took the power of the original titan? It would be one thing if the Reis somehow took that power from them (but why are they able to use it when Eren can't?), or if they changed names at some point, but even Zeke's narration during the Wall Maria fight, just a few episodes ago, was referring to "King Reis" and what he had done. I'm a bit confused.
Another bit that felt a tad weird to me was that, in her flashbacks, Historia was reading a book about what sure looked a lot like the ancient origins of the titans... except the girl wasn't called "Ymir Fritz", there, but "Krista"? If that book is supposed to be suppressed knowledge (and Historia or her half-sister had it because of their bloodline), it's a bit odd that they still changed the name... and if it's not, it's odd that they didn't change more, isn't it?
I read a comment saying that the titan that ate Eren's mom looks like Dina,mind blown if that’s true(highly unlikely but cool).
Consider that Eren could only use his scream power when he touched that particular titan. He had been in contact with other titans (even intelligent ones) before and after that and nothing happened then. Could be because that was indeed Dina and her royal blood (like when Historia and her father touching him triggered hidden memories).
Also, when that happened, Ymir thought to herself that the world inside the walls might not be hopeless after all, and looked at Historia. I imagine Eren could use his scream power again,
with Historia's help?
(although, like I said just above, that sounds like two different royal families... confusing!)
Wasn't Frieda a shifter? What happens when a shifter eats a shifter? Is the power lost forever?
It's apparently transferred (Zeke once talked about giving Reiner's armor to another warrior, and that sure sounded like a threat). Although in that particular instance, it looks like Eren not being of royal blood meant he couldn't really use the power, which is why Historia was to eat him.
It could be possible that the other was the one Grisha used to convert into a titan in the first place before he devoured Frida, but maybe he was just a mindless titan at that moment.
Note that he didn't turn by injecting himself with some fluid, that night. He just cut himself with a scalpel, meaning he had the power to turn at will already. He must have eaten another intelligent titan at some point. Maybe we'll see how that happened next month.
