When Eren first sees the small figure curled into himself, unmoving on the swing, he thinks it's a hallucination. It is impossible, because the Corporal is supposed to be his superior. He is supposed to be more experienced, more refined, more mature. But now, Eren is staring at that familiar face, posture... On a child. He has to blink to make sure his mind isn't just fucking with him, because it's just not possible. Surely reincarnation isn't playing some stupid trick on him? But the more he stares, the more obvious it is. That child isn't some carbon copy of his former Corporal; that person is definitely Corporal Levi. ...Right?
