Being weird and being a part of the 104th cadet corps, is not for the weak. You already knew you were well disliked before you even joined, but it feels like just recently people hate your guts. Even Levi! And he's friends with Hange!
You guess having interests about space and time is apparently a crime. The only one who didn't seem to hate you was Armin Arlert. You already knew from the start that he was also a bit "weird". He was always talking about things and discoveries beyond the wall, freaking everybody out sometimes. But he's so nice he barely even gets picked on.
"You okay?" Thinking about him must've brought him to your direction. Because now on the airship, he sits next to you as you crouch on the floor. The plan for the night raid had gone off the rails, Eren seems totally crazy, and now you're sitting alone wallowing in self pity that shouldn't even belong to you.
