If Rosie had flipped scum, I'd have flipped my read of him. As it is though, his willingness to vote Rosie is null because it still got rid of a townie which scum needs to do anyway.
I'll see how the day unfolds a bit before I place another vote, but my reads thus far remain unchanged.
It is worthy to note that the gurds DO NOT KNOW WHO THEY ARE.
IOW, if she had flipped scum, it does not mean that those voting for her or even pushing her wagon were not scum. They don't necessarily know that they are lynching one of their own.
That makes scum hunting particularly difficult in this setup - the scum are not necessarily working together.
