So I think one of my favourite twists in the series is Kruger's first name being Eren. Also, based entirely on dialogue between him and Grisha, my theory is that Kruger's a royal (hence his father joining the revolution) and why he knew Dina. Kruger being a royal would also explain why he didn't just go and take the Founding Titan himself (he wouldn't have been affected by the vow that the royals inside the walls are, but they make it sound as though the person possessing the Founding Titan needs to be
separate from a titan who has royal blood. I dunno.)
The 13 year lifespan thing is pretty brutal. For Eren and Mikasa to go to all that effort to save Armin only to essentially doom him... And for Mikasa to learn she's going to lose her family AGAIN... I feel for her.
I remember when this chapter came out and everyone went "OH GOD DAMMIT" at the Attack Titan twist. I don't think anyone had guessed it correctly before, and honestly I find it impressive lol.
Also Kruger mentioning Mikasa and Armin... I want to point out, before anyone brings it up, that this is
not the same line Grisha says to Eren before giving him the injection. Kruger's line talks about Grisha fulfilling their mission. Grisha's line to Eren is about how he has to learn how to control his powers.
WHAT DOES IT MEAN, ISAYAMA? WHOSE MEMORIES DID KRUGER SEE?
I assume Eren's, but fuck this cryptic shit lol.
FWIW the Ymir flashbacks happening when Historia reads the letter didn't happen in the manga. The letter was when they showed/explained Ymir's backstory in the manga instead of earlier on (which is one of the changes to the anime I didn't really like as it kinda makes a couple of things more obvious, but whatever). I think they also partially did it to remind people about the paths and show Ymir being "reborn" for lack of a better word.
PS Have young Kruger, who's the most important part of this episode.
