Is history going to repeat itself?? The ending scares me. What did the child see in the tree? Someone explain please.

Jumping in here to say that it's an open-ending for a reason. The story is about human nature and the cycle of conflicts. The world in AoT has always been grim and brutal but never without hope. The ending suggests that history may repeat itself, but there is also reason for us to hope for a different future because the child at the end is very different from Ymir. While Ymir ran for her life, pursued by hounds, the child is on an adventure, carefree and happy with his dog companion. If Titan power was created by Ymir's repressed desires for freedom and hatred for the world, then the power this child creates, if one was created at all, will be very different :)

I wouldn't say Eren "sacrificed" himself because that implies nobility on Eren's part. Eren wanted freedom and was willing to sacrifice the world for it. He started the rumbling, knowing full well that his plan to exterminate the world would eventually fail.
Eren's objective was freedom for himself, for Paradis, and the safety of his friends. He never meant to achieve peace, because he knew full well that human nature would always entail conflicts and wars. Even if he did succeed in exterminating the world, Paradis would probably start fighting among themselves, as did the Eldian Empire after conquering the world.
In the end, Eren did get what he wanted, except freedom for himself, because ironically he was a slave to freedom itself.

Why comment section screaming “I allow fictional stories to affect my reality and mood”. Y'all need to chill and protect your peace. Some fictional story is not worth the discomfort. Go touch some grass

I don't get depressed if a story is sad or ends badly but it does impact my mood. I do things like reading and watching series and movies to enjoy them. It's entertainment. If the entertainment value isn't there, then, I feel bad for investing time into it. If it was something I read in a couple of minutes, I couldn't care less. But spending months and years waiting for the next chapter does impact a person's mood
Who’s this new character???
I assumed it’s Wren in Human Form but Wren does not have a mole in vampire form. Wren is also not half human so I don’t think he changes forms like Ethan. Don’t mind me, I like to argue with myself in there comments
It's Lee Nam-Joon the actor they mentioned Ethan will be working with in the last chapter.
Oh Ok, Thank You
