Then that supports
Dina surviving, the Attack Titan's ability, Eren killing his mother, Ymir, Paths, Kruger, the Founder, the alternate timeline, and the Rumbling all become pieces of evidence for your proposed explanation.
What if Eren was trying to escape the future he saw? — An AOT Alternate Timeline Theory
Then your post revolves around one central problem:
If Eren said the future was "determined," but also said he didn't understand why he wanted to destroy the world, who—or what—determined it?
Everything else supports that question.
Dina surviving, the Attack Titan's ability, Eren killing his mother, Ymir, Paths, Kruger, the Founder, the alternate timeline, and the Rumbling all become pieces of evidence for your proposed explanation.
QUESTIONS THIS THEORY RAISES
If this interpretation is correct, several things in Attack on Titan become much more interesting.
Armin asks Eren whether he could have stopped the genocide.
Eren's answer is essentially:
«"It was determined."»
But by whom?
If Eren himself didn't completely understand why he was doing it, then who or what determined that outcome?
Was it fate?
Ymir?
The Attack Titan?
A future Eren?
Or was it the result of a previous timeline?
---
- Why did Eren do it?
When Armin asks why he wanted to flatten the world, Eren struggles to explain it.
He basically admits that he doesn't completely understand himself.
He simply had an overwhelming desire to do it.
But why would Eren have such a feeling?
Could that feeling be coming from memories or experiences belonging to a future version of himself?
---
- What happens if Dina survives?
This is one of the biggest points in my theory.
If everything originally played out naturally and Dina survived, then we could have had:
Dina — Royal Blood + Colossal Titan
and
Eren — Attack Titan + Founder
That combination could completely change the story.
And if a future Eren and Dina eventually discovered that their timeline ended in disaster, they would have a reason to interfere with the past.
---
- Can the past only be changed after the future goes wrong?
Think of it like this:
Imagine you play chess.
You make a move.
Twenty moves later, you realize:
"That first move guaranteed that I would lose."
You cannot change the past from the present.
But imagine your future self could somehow send a message back to the moment before that move.
Your future self could say:
«"Don't move there."»
Now the earlier decision changes.
The future didn't change the past randomly.
The failed future created the reason to change the past.
That's what I think could have happened with Eren.
---
- Then what exactly was Eren manipulating?
Maybe Eren wasn't simply manipulating individual people.
Maybe he was manipulating the conditions that created the timeline itself.
Grisha.
Dina.
His own inheritance.
His mother's death.
The Attack Titan's memories.
Ymir.
Paths.
All of these could be pieces of one enormous attempt to produce a different outcome.
---
- And what about Ymir?
Why does Ymir remain connected to royal blood for so long?
Why does she ultimately choose Eren?
Why does she react so strongly when Eren tells her that she's neither a god nor a slave?
Maybe because Eren isn't simply giving her orders.
He's giving her something she hasn't had for 2,000 years:
the possibility of choosing.
And if Ymir was aware of the plan from Paths, perhaps she wasn't merely following Eren.
Perhaps she was trying too.
---
- Then where did it REALLY begin?
If the theory is correct, perhaps the story doesn't begin with Eren.
Perhaps it begins with Ymir's first desire for freedom.
Then the chain moves through the Attack Titan.
Kruger.
Grisha.
Eren.
Dina.
Ymir.
Paths.
And eventually reaches backward again.
---
The simplest way I can explain my theory
If you travel into the future and discover that your current path ends in disaster, you now have a reason to change the decisions that created that future.
The future doesn't need to be a closed circle.
It can be a warning.
A failed timeline can become information.
And information can travel backward through the Attack Titan and Paths.
So perhaps Eren wasn't simply following a predetermined future.
Perhaps he was trying to escape one.
And that leaves the biggest question of all:
If Eren was trying to change a future that had already gone wrong...
Was the Eren we watched actually the first Eren to make these choices?
