I hadn't seen the thread
End of Armin Mikasa and Erens character arc. 137, 138, 139
The Eren from Mikasa dream is just a headcanon created in Mikasa head to help her to cope:
Fuck Aaron Yogurt.
A disgrace to the Yeager family.
AU isn't possible cuz there is a big time paradox/plot hole, who was noticed by some.
Had Eren run away, he would not had the chance to get to Paths with Zeke---> No Grisha killing the Reiss---->Eren doesn't inherit titan powers and Historia dies. Eren too die.
Basically the events that happens after the day the wall is breached is rendered non-existent.
And it was confirmed all of this is Mikasa dream
About Eren dream in first chapter
That's why, at this very one moment: Aaron Yogurt & Eren Yeager (just before being beheaded) have same shifters marks.
We can say real Eren was able to see Mikasa (The Mikasa from her own dream) from his imaginated version of Mikasa ("see you later") Aaron Yogurt. And with PATHS magic there is a connexion from current Eren to chapter 1 Eren. It's a kind of mindfuck similar to Past Eren who sees Future Eren memories through Grisha memories.
So we're done with Mankasa and Armong characters. So now we are left is Eren PoV (whether he is alive or dead, I think he is physically dead but still active in PATHS).
The next chapter will be about the end of the curse, whether the Rumbling will succeed or not, wish of Ymir, Eren PoV and obviously the Historia/baby mystery (Eren's answer to Historia's question about having a child). All of this will be connected.
I hope for some deaths in the alliance, probably Jean and Cornelius (their last words were moving), I think Gabi will be saved by Reiner who will sacrifice himself.
Otherwise strange the transformation of the Titans, is it Falco's scream that did this.
