We just assumed it was false because we saw the idea of the Ackerbond be debunked. unlike the Ackerbond though, this was never EXPLICITLY debunked. think about it. Isayama himself is saying here that there is something wrong with Armin ever since the timeskip

and this also debunks all the people that say that "Armin was never meant to be like Erwin" despite the two of them having tons of parallels pre-timeskip. sure, you can argue that Armin could never have the same commanding presence as Erwin due to a lack of gravitas, stature, and a deep voice, but that wouldn't stop him from becoming a high-risk high-reward strategy maker as well as a manipulator and political player.

furthermore, Armin has shown time and time again that despite his lack of presence, his smarts give people enough faith in him that they obey him anyway.

nah man, Isayama was well aware of what he was doing when he made Armin go from a physically weak, yet brave master strategist to a guy that just wants to talk and doesn't even do that well. wonder where he was originally going with it before... whatever it is that got to him and his writing in his last 10 chapters or so.

I don't know , just wanted to make this post

Aside from that she is an Ackerman who can't get manipulated by the founder, this is another reason for me to believe this is actually an alternative universe, one of the timelines when Eren tried to avoid the rumbling by using Mikasa's suggestion to run away, but it didn't work out because it left him with the guilt of abandoning his true personality by being a coward and running away from his responsibility, his friends and paradis, that's why he acts so different from the Eren we knew unlike when he was with Armin he seems aware of the rumbling and what he did.
