I can also see myself being wrong and that's why I'm still not sure on what his alignment is. What he said is nai and I even said I am wary. I do still prefer he develops his own reads because if he continues to just sheep the consensus in later days then he will continue to remain in the poe.
Scum does sometimes make a play like this and I know this from experience. Either it comes from scum or it comes from lazy town. I remember a completed game I have with Rej when he was scum he said along the line he would sheep the consensus.
