GOD DAMNIT ISAYAMA.

I almost shed a tear, you're one of those few that comes up good theories about the last chapters in this ocean of ignorants.
I wonder if Armin and eren will indeed fight each other but will Armin suddenly change in one and only chapter "100?" I can't believe the manga will end at chap 100.
I believe the dude who made both of piecke and falco fall is Connie and the 2 men behind billy are probably, Armin and jean.
Also I think Zeke knew about Eren's infiltration.
And piecke most likely played along with the man(Connie) that made them fall in the trap.

Gosh ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄ thank you for the praise! Sorry this is long
Ngl, I didn't think of Connie, until after I read your comment I googled Connie's face (manga) I can see some similarities in the eye shape! That's a pretty good assumption.

I don't think that the series will end at chp 100 but I think it can be wrapped up around chp 115-120. Isayama did say that we were close to the end of the story.

Also, I tried looking for the two men behind Billy, but I couldn't tell which page that was. I was hoping that you know what page or chapter it was. Yeah, I'm sure Zeke has an inkling on the infiltration but I don't think that he knows it's Eren specifically.

Willy Tybur (Taybar?? from ch99) definitely know that Eren is there (ch98 p16). Also, it makes me wonder from his speech in 99 how did he get that information from behind The Walls. It couldn't have been Reiner or Ymir because they weren't there to see Historia's coronation. I don't think they would have spies back there since SC already knows about people like Reiner they wouldn't let random people inside the walls again. So rather than Zeke, I think the one Eren sent his message too was Willy. Zeke would be loyal to the state considering he did rat out Grisha- and Willy has been working behind the scenes with that general (c98 p14).

Ever since Eren got the Coordinate power, and how he realised its power and how to use it (with the blood of a Royal). It does seem like he's doing something behind the SC. Eren may not be as smart as Armin or Hanji but he does have capabilities to make up plans.

I guess that's because eren has matured, and now since he has realized many secrets, he is calmer,smarter ..this is great character development. (Goodbye whiny annoying eren)
I never found it logical for eren to send that certain letter to Zeke, however I still don't think he sent it as well to billy.. Or willy, but I wonder how he knows about eren Kruger as well..might be willy knows more than we imagine or we except. But if I remember well, in chap 81, Zeke told eren he will save him ? But from what and when? And will that happen in chapter 100? ...for some reason I feel like Zeke will betray marley but at the same time this does not make sense, since we know he snitched on his own parents for marley,
I'm curious to know if they will animate the part where Zeke and Levi fight, it gave me chills, will they compress the arc? ..I heard season 3 will be only 12 EPs. I really want to see the battle with Erwin and the beast titan.
Maybe eren sent that letter to an 3rd options we don't except? What if it's the doctor that grisha used to trust...

imo Eren has always had that ability but it's constantly gets overshadowed by his recklessness, like the first time the Shiganshina trio found out about titan eren- Eren proposed two options to Armin. Eren leaves Wall Rose by himself and try to get to Shiganshina or Armin tries to talk the Garisson.

I still believe that Zeke is VERY fishy, he spouts a lot of propaganda out of his mouth but they always feel fake. Like he's lying to your face because maybe there are a lot of people monitoring him, or maybe it's because it's propaganda that's why it feels fake. I hope this makes sense to you.

If S3 only gets 12 Eps I don't think that will be enough to go over the Uprising arc. At most 12 episodes will be enough to show Kenny's demise and Erwin's announcement to go to Shiganshina.
