Unfortunately, the same as your list of "possibles"– except that I really don't have any idea about
Gwath (and I'm half-inclined to put you on it too,
Lily, just because I know how sneaky you can be

).
One thing that I've been thinking is that the wild performances by
Nogwolf and
Wolfegil might have been inspired by their desperation at leaving everything in the paws of a newbie, i.e.
Ilya.
Also,
Nogwolf gave
Ilya what looked like parting advice in his last post. I wouldn't want to read too much into that, though, not when
morm had already addressed half the village as fellow-wolves.
