Several times, Eugene shows to be quite insecure and afraid. Though at first, he doesn't seem like the type to care very much, he worries about the people around him and especially worries about the situation. It is especially ironic because Eugene doesn't tolerate dishonesty. He dislikes thinking about "what ifs" because he sometimes fears that the apocalypse may never end. He knows people like Harry, Lawrence, Ethan, Zion, Scarlet, Judy, Hayley, Jay, Sue.
