I agreed with some of Johnny Bravo’s arguments about hawkeyop and Biotop. He thought they were the last 2 scum. I agreed in that, if hawkeyop was scum then so was Biotop.
The converse isn’t quite as strong as I suggested, but the argument against Biotop was lessened if hawkeyop was town.
Given that, the choice of Scathach was clear: if it’s a mislynch then there are strong pointers to the 2 remaining scum. If it is a correct lynch then we have lots of time to find the one remaining scum.
