I've seen this ep dozens of times, if it of my favourite Eps of B5. It is written from the POV of two "salt n peppa" maintenance workers- Sort of like "Lenny and Squiggy" (of Happy Days) characters. Basically, what makes this great is Harlan's gift for taking the Mundane and mixing it with the Fantastic.
Raymond O'Connor and Lawrence LeJohn are "Mack" and "Bo" - Two regular B5 Maintenance joes - Who just happen to cross paths with all of the major B5 Season 5 players through the course of this 'sode. These guys are great Character actors and VERY well cast here.
Their insights are our insights, their comments are our comments. It was as if, these guys represented the viewers and fans of B5- Given a voice through Lenny and Squiggy/Mack and Bo. - So their comments are our comments. Like for example, their speculations as to what happened to Ivonova.
One of the best parts of this Ep is that the "Bo" character, respects the "Flight Jockeys" - The guys who drive the Star Furies - And secretly wants to be one of them- In one of the best eps for Byron, Bo is given his dream, by Byron.
As much as I disliked Byron's character, we never got to see this part of him that much - The part who, if approached earnestly, would grant you a boon if within his power.
During the first few eps of Season 5, as Byron is being introduced, you want to think, "this guy could be a good leader IF he just did things the right way" - But he constantly made mistakes, making enemies of Zack Allen and the rest of security, being in the wrong places at the wrong time and being imprisoned so that he could not intervene when the other "teeps" start acting out, and it did not help for Garibaldi to try to force him to help out his own little "Secret Agent Club" - If Garibaldi would have ASKED, instead of being Garabaldi...
And it also did not help for Zack to be jealous of Lyta, causing more animosity between the Teeps and B5 security. This 'sode occurs right after the teeps had helped thwart an invasion, but before they made further nuisances of themselves.
It's just a regular day on B5 - Medical Emergencies, Intruder Alerts, Sheridan being overprotective of Delenn, my favourite part is when Bo is given the gift of flying in a Star Fury by Byron- It is the best interaction between a "Teep" and a "Mundane" in the whole of Season 5, there is a real connection there, for both Byron and Bo. Byron could have done more like this, if he were allowed to, if he would have allowed himself to do it, instead of secluding himself and the other Teeps in Brown Sector.
But as JMS has said, he was trying to introduce a brand new kind of Prejudice. But this Ep was before all things went bad for the Teep colony of B5.
