Think about it, Gregg has already said that the person Rei was sleeping with in college was an established Eva character, and who else is available but one of the dummy plug clones of Kaworu . . . and Kaji?
- One of the Nu Ree
- Yui Ikari
- A First Ancestral Race
- A duck
- King Arthur
- An alternate reality transgendered Asuka
- Nobody. In reality she was born like an amalgam of DNA samples of Asuka Langley Sohryu, Kouji Kabuto, Tetsuya Tsurugi, Duke Fleed, Ryoma Nagare, Hyoma Aoi, Kenichi Go, Kazuya Ryuuzaki, Banjo Haran, Hiroshi Shiba, Akira Hibiki and Guy Shishioh, made in order to create the ultimate Hotblooded pilot. Decades later her line will give birth to Noriko Takaya and several generations later to Kamina.
- A Gender Flipped Rei.
- Given that Pieter is genuinely trying to become a good father in the rewrite -and Word of God has told getting married his second wife is punishment enough-, it's unlikely he will behave like he did in the original fic (actually it's possible if he visits Tokyo-3, he has a heart-to-heart talk with Unit Two). So Asuka's stepmother will make a fuss, Gendo will dump her in the pool... and laughs will follow (Rei will record the scene. Asuka will pay cash for the tape).
