The lobby of the hotel that Kori/Starfire is talking to the concierge in is actually liuna station on James Street North in Hamilton Ontario. Liuna is famous for leaving a sign in as advertisement and is shown at the top centre of the screen as the scene zooms out after Starfire asks for coffee.
The episode premiered at New York Comic Con on October 3, 2018, before later officially premiering on DC Universe on October 12, 2018.
Some scenes were filmed in and around Hamilton, Ontario, Canada (doubling as Detroit, Michigan) - as evidenced by the white, yellow and blue painted bus of the HSR (Hamilton Street Railway) at the corners of Grenfell St and Beach Rd in the early part of the episode. The bus number - 41A is the Mohawk Road route.
The first live-action appearance of Raven, Starfire, and Beast Boy.
The old computer game that a night guard plays (in s01e01, 47min mark), is called Crystal Castles from 1983, Atari. It's funny because he seems to have the newest games available yet plays this oldie. Also, the Titans (originally from around 1964) had a very strong comeback in the 80's when the Teen Titans was revamped with Starfire, Raven, and Beast Boy (Changeling) (and others) (Hawk and Dove are from the earlier version of the Titans, which is kinda how they are depicted in this series)
