SHINJI: So Ayanami, how come we have never seen you smile? ASUKA: Yeah Rei, don't be shy and show us a big smile! REI*smiles* SHINJI: OH SWEET ZOMBIE JESUS!! ASUKA: MAKE IT STOP SHINJI! MAKE IT STOP!!!
Holy hell, this scared the crap out of me. And I've already read a bit in both Angelic Days and Shinji Ikari Raising Project, so I've seen Rei smile. Just, not so creepily...
