Rei Ayanami was not what most people considered to be an
overly emotional girl. In fact, some
questioned whether or not she HAD feelings at all. Shinji Ikari had always felt different, and had even seen her
smile once (even if it had been his suggestion), but being a shy boy he didn't
quite know how to approach her.
However, even given his conviction that she might have more
emotion than she let on (or was capable of showing), his mouth dropped open as
she gently laid a hand on his arm as he got up to leave school one day.
