I thought the episode was good in that it asked you to consider what was more important, justice or immortality. How big a price would you be willing to pay for immortality?

Then we had Kosh at the end saying, *windchime* You are not ready for immortality. *tinkling bells* Boom.

I wonder if one of the reasons he is on the station is to make sure the younger races don't 'forget their place', since naturally they aren't as good as the Vorlons. [insert sarcasm here]
