On the other hand, it's very unlikely that any of the Big Four (Eren, Mikasa, Armin and Levi) will die; the first three because they are the protagonists and the series revolves around the realization of their dreams, the fourth because he is too damn popular. I think the fact that the series has revolved around Eren and Armin's dreams is WHY Armin could die on the expedition. In the newest chapter, we get to see Armin's dreams to explore the outside world with Eren and Mikasa reignited, with a promise for the three of them to go explore the world beyond the Wall together after the mission. This sets up the perfect scenario to have Armin tragically die on the Expedition, which would absolutely crush Eren not only because Armin is basically his only friend besides Mikasa, but because he would no longer be able to keep his promise to explore the wider world beyond the Walls.

Personally, as soon as I saw Armin and Eren promise to visit all of the amazing and unbelievable scenes beyond the Walls together after the Expedition, I thought to myself "Well, it was nice knowing you Armin."
