I have only seen the anime and haven't read the manga, but a question came to me:
Can the titans swim?
We know that they are abnormally light and strong for their size. However, the fact that they evaporate after dying kind of suggests that they are formed of some sort of compact water vapor, so should we expect them to melt when they come into contact with water? It's not like they disappear when it rains... Or maybe they can't swim because they're too stupid
Because, if they can't, this place in Paris could've been a possibility for humanity.
