After being mentioned in the previous episode, Kasidy Yates makes her first appearance in this episode that begins her four year courtship with Sisko.
During this episode, Rom states that Quark hadn't returned to their mother's home in twenty years and that he'd left as soon as he reached the age of ascension. If the Ferengi age of ascension is age eighteen (as stated in "Heart of Stone"), it is thus intimated that Quark is thirty-eight years of age as of this episode.
This episode marks the first time we see Ferenginar.
Quark: (Standard Ferengi greeting) My house is my house.
Brunt: As are its contents.
Rom: (holds up his arms) That's enough bickering! You're both acting like children! I will not stand by and let this family fall apart! Quark, you should be ashamed of yourself. I've seen you treat Cardassians with more respect than you show your own mother. And Moogie, if Quark can uncover your hidden investments, eventually the F.C.A. will, too. And all that profit will be lost. Think about that for a moment. Now, neither of you is going to leave this room until you've settled things. Is that clear? AND NO SHOUTING!!! I'm going to take a nap.
This episode reveals that baseball is still played within the Federation. Kasidy Yates youngest brother on Cestus III plays baseball for the Pike City Pioneers there.
