I was a bit confused by some of Delenn's dialog. I took it to mean that Kosh was not a Vorlon, but that he was one of the "Ancient Ones" posing as a Vorlon, with their support. I looked it up and saw clarification that they meant "all but one species" of Ancient Ones. And so Kosh either looks like an angle or maybe his form is dependent upon your own perception? I had seen what a shadow looked like before, commercials in the 90s. Those guys are cool.
Why didn't the Vorlons and Minbari vaporise Z'Ha'Dum back at the end of the war 10,000 years ago? Or whatever it was that happened 1,000 years ago? That actually made it seem like the Shadows aren't much of a threat. Maybe because the Shadows are predictable and always gather in the same place? Like it's easier to keep tabs on them?
If the Shadows have to manipulate from, well, shadows, like using Morden and setting the other powers at one another's throats to distract from them, why are we scared of them? They've been beaten so many times before. Are the Vorlons now weak enough to be conquered? The Minbari are losing their souls, are they actually becoming weaker? Don't answer.
There is a Vorlon proverb: "Understanding is a three edged sword". It will all make sense soon enough.
