To address your points:
1. I didn't see twenty two as a townread. I saw him as someone pretty scummy and flying under the radar.
2. If I begin to think someone is towny then I'm going to make sure that I slow the lynch train THAT I STARTED on that person. So when I saw signs of town in Fury, I hopped off and tried to get a viable countertrain on someone scummy.
It think would be borderline gamethrowing if I started townreading Fury but decided to keep pushing for his lynch just to keep my credibility intact.
