I'm praying they won't go that path, I don't want to see them hurt each other.. You can tell when they met each other after those 4 years that they somewhat adore each other, though Levi kicked him in the face. lol. Levi feels some sort of responsibility / protectiveness towards Eren as I see it. I'll be devastated if they sacrifice Levi.. ╥﹏╥

I've seen in the comments that Eren might be mind controlled with Zeke's body fluid or something. Eren will have to go through Levi if he wants to talk with Zeke. So... Eren has to wake up from his mind controlling before he does something he might regret to Levi.
(Yes, this comment is about Levi. Because I like him the best. Deal with it.)
My suspect is that Levi will get hurt or die and it will trigger Eren to wake up and realise what he's done.(I do hope the fuck it won't be like this tho)
Or maybe Levi is aware of Eren's behaviours and he was questioning Zeke about how he turned those villagers into titans because he suspects Zeke is doing something to Eren. If Levi realizes what is going on, he can act before Eren does whatever Zeke is planning.
But surely there will be a "Levi vs. Brothers" in both options.
OR I'm underestimating Eren's loyalty to his childhood hero and he won't act against him no matter how mind controlled he is.(Which is unlikely because he DID act against him before in my opinion. I remember how they fought when it was choosing between Erwin and Armin.They both wanted to save their friend. Sad that they had a fight there. I don't like remembering that scene.)
If you think I got something wrong and want to adress it, please notice me with kind words.
You do realize that I'm a big fan of Levi and Eren. And I did get called on it before(like it was something to be ashamed) so I'm wary of commenting. But I've managed to get over it thanks to myself. I'll write about Levi and no one can stop me.
I like my heichou! ヾ(❀╹◡╹)ノ~
