This is the 900th episode of the Star Trek television franchise.
The end credits mention "In Loving Memory of Allan "Red" Marceta", Allan Roy Marceta was a member of the art production staff. He was tragically killed after being struck by a vehicle on his motorbike in Trenton, Ontario, Canada on August 22, 2022.
At the end of the scene where Tilly and Dr. Culber are talking in the bar, the camera pulls back at the end of the scene. You can see a character seated at the end of the bar who looks suspiciously like Morn from Deep Space Nine. The bartender is also a Ferengi. These two points appear to be a nod to the sister series where Morn was a fixture in Quark's bar (the Ferengi).
