Also, after watching this episode I watched its preview just because I felt like it. The preview was pretty misleading, to the point where it was almost outright lying about what would happen in the episode. I'm guessing that it wasn't the people working on B5 that made the previews back when the show was on.
Definitely not. In fact, JMS would warn us from time to time to *avoid* some of the particular previews in order to avoid being spoiled. Some of us always figured that the recipe for the previews was, "One the next Babylon 5! [insert random character images] Something we don't understand will Blow Up Real Good [insert random explosions] and Tensions Will Run High! On the next...Babylon 5!
