I noticed one thing in Roa's posts yesterday, she said she thought that all original wolves were dead. Which makes me suspect all the more that Alcarillo was an original wolf.
This means that Zali and Oddwen, despite appearances to the contrary, are probably innocent. If my theory is correct, the early wolves are accounted for.
Zali and Oddwen were too suspicious to be Four or Five wolves, and too low-key to be the all-important Six wolf.
Spawn, my dear, with your brains and experience, you also fit the bill of a Six wolf.
