You and others rode far away from walls and then you all came to one place... It's end of Paradise Island and Levi, Hange, Floch, Sasha, Armin, Eren, Jean, Mikasa and Connie see sea for the first time. Armin had a dream to see sea with Eren and Armin and their Dream came trought. You saw beach when you was young but no one else saw sea, ate ice cream, saw car, photo or something like this. For then It's first time after many many years. Levi will stay on beach but others will try enjoy sea.
