Instead of "The Real Folk Blues" playing at the conclusion of this episode, "Space Lion" plays with a credit sequence similar to that of the final episode. This is because this episode is considered the end of season 1.
The end text to this episode reads "Do you have a Comrade?" instead of the usual "See you Space Cowboy."
This episode ends with the same opening quote of Jupiter Jazz: Part 1 (1998). Presumably, the audience is supposed to think the quote is in reference to Spike when heard the first time, but it is made clear that it is about Gren the second time it is heard.
