An excellent twist this episode as Zeke paraded Errand around these memories trying to dissect just where he was brainwashed by Grisha only to slowly realize that he had pretty much always had a few screws loose and was willing to kill for his freedom. Finding out that not only did the attack titan give future memories, but that Grisha had been staring down based Eyron during those pivotal scenes as well was a delightful recontextualization of what we thought we knew about events thus far, including the killing of the Reese family. Little details getting glossed over have a way of coming back to bite the viewer's behind in Attack on Titan, and I love it.
Brilliant.
I didn't think of that. If he appeared to dear 'ol dad, it makes sense that he would to previous holders as well.
No doubt the rumbling is coming, with that warning Grisha gave out.
