Well, maybe "ran away" is wrong, but one second, he's there, talkin' to Delenn, and then she turns towards Lennier, who was approachin'. When she turns back, Neroon is gone.
After finishin' up this season, I'm takin' a break for the weekend, since I picked up Friday Night Lights
the other day, and there are new episodes of Doctor Who
to watch tomorrow & Saturday.
So, I probably won't get to the fourth season 'til next week.
I'll let ya know if my opinion of Neroon improves.
