Kosh and Sheridan: I was speaking of intermittent contact. The actual splitting off a piece of himself did come in Interludes ('Remember' I always think to myself, all Spock-like), but I like the idea of Kosh dipping into each ambassador occasionally to figure them out/nudge them along or perhaps even just voyeuristically.

That aspect of Lorien doesn't bother me; we're the teenagers now, being given that last little push out of the nest. Lorien helps set it up, like a good parent, but then stands back and lets us make the final decision. And after all, he's the Shadows and Vorlons' parent too. It felt more like a family meeting than an intervention.
I just thought it went on way...too...long. And I hated the 'fingers of mist' holding Sheridan in mid-air. Like I said, I was much more philosophically inclined the second time through (older at least, if not wiser) and liked it more.
