In the previous season, Eren Yeager was faced with a tough decision: whether to follow his friends into uncharted territory to discover what secrets it holds or stay behind and battle a dangerous human opponent. In Attack on Titan Season 3 Episode 12 “Scream”, Eren chose to take the risky journey inside the void alongside Historia Reiss and a little girl named Falco.
In the final minutes of the episode, however, Eren disappeared from his fellow Survey Corps members’ vision along with Historia and Falco. While it could be taken as them simply vanishing into thin air, there’s one other explanation for their disappearance: they were transported to another dimension in order to avoid the explosion of the Berg Newspapers building. This would come as a relief to fans since Eren’s survival ensures that there is still hope for him to fulfill his destiny in saving the world from the creatures known as Titans.
However, not everybody believes this theory, and some people think that it’s possible that Eren will eventually wind up dead.
