Don't torture me with that picture?
I would definitely preserve the Necro. When I was coven, the Necro was so damn useful, it was a gold mine for various plays.
Anyway, who are your suspects now after Sallu/Krogo and Juliet's flips? Xlaw might actually be town tbh.
I saw him suspecting Krogo last day phase as well, and it didn't seem like a bus attempt to me.
