Given the size of the village, maybe the victims were chosen because they had no connection with the villains. The Seer, in any case, should not be giving away anything on Day One.
In Post #91 Wilwa mentions: Skip, Lottie, Gil, Mac, Lommy, Boro, Rikae, Kit and Nerwen. The village would obviously assess what this could mean, because there could be something Seer-ish in Wilwa's notes - leaving the unmentioned in the shadows for an extra day. They would be:
Me (I suppose
)
Eowne
Inzil
Enca
Green
Wyth
Mac
Cop
Nog
Volo
Sally
So if the lions weren't really expecting the Seer to be findable, and chose Wilwa because of this, then I'm sure two of them at least are in this group.
Can't believe they actually got the Seer, though. That Lannister filth always gets lucky somehow.
