From Wikipedia: "On April 15, 2015, Anno spoke about his feelings regarding Asuka and Rei. He claimed: "The truth is, I have no emotional attachment to Rei at all. In the midst of making Eva, I suddenly realized that I had forgotten her. Her very existence. For example, in episode seven, I remembered and added one shot with Rei. I had no attachment to her at all. I think that was okay, because in episode eight, she didn't appear. Not even in a single shot."[
