When Odo and Worf are in the bar on D7, a Starfleet Officer in a command gold shirt and CDR's sleeve stripes walks by in the background. On TOS, Mr. Spock is the only full Commander ever seen on Enterprise, and Scotty was third in command and he was only a LCDR which means that either another starship was there (which there was not), or there was an extra CDR with command status on Enterprise never mentioned.

[Sisko and Dax are frantically scanning tribbles in the grain bin for the bomb, throwing them aside as they scan]
Mr. Spock: [inspecting a tribble] They seem to be gorged.
Nilz Baris: *Gorged*? On *my* grain? Kirk, I'm going to hold you responsible! Must be thousands of them!
Captain James T. Kirk: Hundreds of thousands.
Mr. Spock: One million, seven hundred seventy-one thousand, five hundred sixty-one.
[Sisko and Dax share a look for a moment as Spock continues, and resume scanning]

This episode of "Star Trek: Deep Space 9" is obviously a labor of love that was created to coincide with the 30th anniversary of the franchise. However, instead of just a special episode, the folks who made this went all out and really worked hard to create a treat for the Trekkers and Trekkies out there. How? Using modern technology, they formulated a good plot which allowed the series regulars on the show to impose themselves into one of the iconic episodes of the original series. So, using a combination of cleaned up original footage from "Star Trek: The Trouble With Tribbles", old-style cameras and new computer technology they were able to make an immensely clever episode.

It all begins with some temporal agents visiting DS9. It seems that the crew members recently went back in time and the agents were there to make sure history was not changed and to punish everyone unless there was a darned good reason to make such a journey. What is the reason? A Klingon agent, Mr. Darvin, has arrived on DS9 and the crew later discover he's the same agent discovered at the end of "The Trouble With Tribbles"--and he soon jumps back in time to undo his mistake and change history.

There is so much to love about this episode. It was NOT hastily tossed together and it's fun seeing the new DS9 folks acting like fanboys and fangirls when they see their old heroes, such as James Kirk. Cute, fun and enjoyable even if you aren't familiar with the old series.
