I simply don't see how this affects our ability to find wolves at all.
Quite honestly, I am at a loss right now, as there is no information available to us that wasn't before. However, I am still very curious about your desire to hurry the game along.
It wouldn't even be a reverse-engineer, it's just a case of "hey, look, these guys didn't say they don't have roles."
I completely disagree; This is the most pressing argument against doing what Lysk has suggested. Not seeing this is being blind to the issue at the very least, if not suspiciously disregarding it.
While your and Lysk's point about Cosmos is valid at the moment, that is only because nobody else has answered your call for revelation. Which, in my book, is a good thing. Cosmos has garnered some suspicion from me from his statements, however all that is heavily outweighed by the fact that you, Lysk, are actively working towards his death from the outset, and I will not change my vote, come hell or high water.
