Full disclosure: I realize my above post assumes that
Agan is not the seer, but....I mean really, come on. Even if -even if!- the wolves were afraid of Nimrodel or they wanted to confuse the village or they thought they could reap some other benefit from it, there's no way they wouldn't kill her. Each Day the seer lives is another Day they could reveal a wolf. It just doesn't make any sense at this stage and with these circumstances.
Also, she's
Agan.
Come on.
If I'm wrong on this, I hereby promise to mail
Agan something lovely. It's only fair.
