The monolith that is seen several times in the background of the garden on the Shapeshifters' planet is almost identical to the monolith which appeared in The Alternate (1994) as a 'relic of Odo's people'.
Natalija Nogulich plays Admiral Alynna Nechayev for the final time. This character had appeared intermittently on this series as well as Star Trek: The Next Generation (1987).
Molly Hagan was not available to reprise her role of Eris from The Jem'Hadar (1994), so the character of Borath was created to take her place.
This episode was directed by Jonathan Frakes, who played William T. Riker in Star Trek: The Next Generation (1987).
The line "No Changeling ever harmed another" would return in the season 3 episodes Heart of Stone (1995), The Die Is Cast (1995) and The Adversary (1995), and the season 4 finale Broken Link (1996). This is despite the fact that Odo is frequently threatened by both the Founders themselves, as well as their agents.
