So in chapter 89 of the manga Eren Kruger says to Grisha:

'If you want to save them all, Mikasa, Armin, and the others...'

But this happened in the past when Eren Kruger saves Grisha and gives him the attack titan. When Grisha asks who are Armin and Mikasa, Eren just replies with:

'Hm, who knows. Whose memories could they be?'

So I'm aware that memories are past with the titan shifter, but that should mean that Eren Yeager has Eren Kruger's memories, and not the other way around.

If anyone knows why, please explain.
