For the TV series:
- Actor Allusion: It isn't the first time B.D. Wong has played a psychologist.
- Fake American: British actor Jason Isaacs plays an American Detective.
- Fan Nickname: From before the first episode we had "Green World" and "Red World" for the two realities which only later on the official website have been dubbed "Rex's World" and "Hannah's World."
- Ascended Fanon: In the final episode, Britten is trying to explain what's going on to Dr. Lee, and audibly starts to refer to the other reality as "green" before stopping mid-sentence.
