- Ambiguous Gender: Word of God said that Alex is this.
- Ho Yay: There are quite a few homosexual couples, especially in Episode 1. Janna Maja was married to a woman and Vitali Geren and Gordon Rockwell have been dating for four years. Hayes Suibhne and Micha Reibach might count as well, since some mails adress Hayes as a male while others adress them as female.
- Talking to Himself: An odd variation. The woman that lends her face to Sam is also the voice of Jennifer Campbell's audio logs which Sam can listen to.
YMMV / Code 7
