Are they really so petty about Vorlons? Edit
In the original episode, the Walkers are approached and refuse to assist until Ivanova starts playing on their hatred of the Vorlons. It's presented as her deftly manipulating their petty jealousy.
However, in light of what happens later, I realized it may be something else. Underneath the obvious psychological manipulation, Ivanova makes a good and pretty rational point. The interstellar alliance is lining up behind the Vorlons. The vorlons may have abandoned their role in balancing how they guide the younger races, but if the Walkers and others don't help, then the whole galaxy will consist of Vorlon or Shadow puppets. I think that, implied in what Ivanova says, is what really convinces them. 188.8.131.52 21:49, January 26, 2015 (UTC)
