####Backplot

Before Sinclair asked him to be security chief on Babylon 5, Garibaldi was working for the security division on Mars Colony, where he fell in love with a woman named Lise Hampton. Their relationship was rocky (“I was pretty messed up”) and ended when he accepted the B5 assignment.

The Psi Corps has a secret training facility very close to one of the Mars Colony cities.

There is growing lack of purpose and dissatisfaction among the ordinary citizens on Minbar.

One of Londo’s wives was a dancer at a club, who comforted him when he was depressed. He married her that night, and regretted it the next morning and ever since.

The planet the station is orbiting is called Epsilon 3.
####Unanswered Questions

What came through the jumpgate?

What is the function of all the machinery buried beneath the planet’s surface?

Why was the alien connected to the machines, apparently against his will?

How was he able to project himself to Sinclair and Londo on the station?

Was the defense system designed to prevent someone from finding the machinery, or to stop someone from rescuing the alien?
####Analysis

The alien might well be native to Epsilon 3, since he was able to breathe the atmosphere once he was disconnected from the machinery. In the shuttle, Ivanova can be seen fitting him with a breather unit, presumably since the shuttle’s air is Earth-style. Perhaps the proximity of Babylon 5 to Epsilon 3 is not a simple coincidence.

A possible inconsistency: if the missiles were being fired from within the fissure, how could Sinclair and Ivanova safely enter it? All their cover fire was high in the atmosphere; the missiles could have hit them before they had time to react once they were underground. Of course, it’s possible the missiles are only useful above a certain altitude (true of some present-day surface-to-air missiles,) but in that case, why wasn’t the fissure protected by short-range weaponry?
####Notes

The scene with Ivanova and Sinclair crossing the tunnel bears similarity to a scene from the 1956 film Forbidden Planet. (See jms speaks)
