Attack on Titan is one series that is really known for its plot twists and gray moral areas, hence inviting speculation about what could have been had certain alliances in the series formed. What if two of its central characters, instead of following diverging paths, united under a common cause? What if, in fact, Eren Yeager and Armin Arlert combined their strength, means, and perspectives to fight against Marley? Undoubtedly, this might have remade the scenario into something different, the implications of which are wider than just a fighting concept but rather go to the very philosophy of the series.
