Now might be a good time to go back to 'The Gathering' (special edition only) and watch the bit where Lyta sees Kosh's memory of meeting who he thought was Sinclair. You'll understand part a lot of the spoiler tagging was about back when you watched it the first time.
I don't have the DVD any more, and I'm afraid that some of those spoilers might contain future spoilers, such as how Garibaldi is a secret Vorlon, or something.
Walkabout (***)
A new Vorlon arrives on the station and his name is Kosh, and he is there to replace Kosh so that nobody knows that Kosh is dead, so he obviously wears a completely different encounter suit to Kosh. What?

Kosh 2.0 isn't making much sense. I mean, Kosh v1.01 didn't make much sense most of the time but that was part of his charm, Kosh 2.0 is just being a bit of a jerk. Godsdamn angels, they never tell me anything.
The story about the Shadows feels necessary but not all that interesting. Of course they have to test out whether Garibaldi's revelation about telepaths actually works, but the story itself feels a bit too by the numbers. They fly in with a telepath, they destroy a Shadow ship, the Shadows call for backup, the White Star is disabled, everyone else destroys the Shadow ships. The end. The small sub-plot involving G'Kar serves to make him seem weak, his excuse to Garibaldi for the Narn ship remaining at the station was pathetic. ("But they don't want to go!") We don't even get to see him convince the Narn commander, that happens off-screen.
The walkabout plot involving Dr Franklin was a little better, although it does still have that old television cliché where a serious psychological problem leads to a roll in the hay. I think we can all admit that I have many serious psychological problems, how come women aren't laying down in the hay in front of me?

Also, for an addict he seems remarkably serene, although it has been a few days, possibly weeks, since he quit.
5/10 for the Shadow story, 7/10 for the Franklin story, 6/10 overall.
