- Steve officially learns that Aja, Krel, and Varvatos are aliens in this episode. It's unknown if Steve knows about Stuart as well.
- The character of Gladys Groe, a Changeling spy in Trollhunters, is seen as a waitress at the diner Steve and Aja are dining in during their date.
- Goof: Groe was killed off in the episode "To Catch A Changeling", and it's likely her human counterpart was saved from the Darklands in Part Three of Trollhunters. However, it's very likely her human counterpart would need to grow and mature for a few decades (i.e. likely into her 30s) to reach the age her Changeling counterpart appeared as.
- Steve's middle initial is revealed to be Q.
- On board the Zeron Brotherhood's ship Steve finds a captured cow which he names Bessie. Bessie later falls from the ship but somehow manages to survive and is seen in "Last Night on Earth".
- Bessie's appearance is also in reference to the common idea that aliens steal cows when probing Earth.
