I'll make three preliminary comments about this episode.
I didn't like the Matt Stoner plot. Of the multitude of former relationships brought coming surprising to the station that have occurred on the show, this one bores me the most. We already had Talia having a former relationship from PsiCorps come onto the station with Jason Ironheart having had some new psi power brought out in him at the hands of PsiCorps. Having a second one is just "Eh" to me.
I find it interesting that the original name of this episode was "Pestilence, Famine, and Death." Londo originally called his three wives this back in season one's "The War Prayer." I don't remember if it was brought out in the thread for "The War Prayer," but I'll bring it out here: if Londo's three wives are Pestilence, Famine, and Death -- three of the four Horsemen of the Apocalypse -- does that make Londo War?
And third brief comment: I love the small Ivanova-Delenn hair plot.
