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.

Armin: smile. So this Is...

Eren: I told you, Armin...

You saw sea so you're not much impresed but others are just watching with dropped jaw. Everyone ride down on beach. No one can swim, exept you.
