I'm fairly convinced that SB is town now. I was worried for a bit, but he has since drifted way towards likely being town in my eyes.
When SB asked Yuma to restate his case for Robz being scum, he felt a bit scummy to me. It seemed like he wanted to again bring up Robz's scumminess, which hadn't been discussed recently, but wanted to do so in a way that showed everyone his main reason was someone else's read. I was particularly concerned with his interaction with Yuma. When he asked Yuma to restate his opinion, Yuma said practically nothing new on the subject, simply quoting his original post. Yet, the restating of the old information was enough to make SB switch his vote? The feeling I got from this was that SB was looking for a reason to vote Robz, rather than trying to figure out who was most likely scum.
I was trying to decide if SB was:
(a): Legitimately responding to Robz's accusation, or
(b): Using Robz's accusation as an excuse to focus on Robz once again.
That being said, I have been impressed with the consistency SB has shown responding to MGP's accusation. He responded with the exact same aggression towards his accuser (in terms of accusing them of being scum). This makes me think that his initial accusation of Robz was based on the accusation rather than an underlying motive, and my initial read was wrong. Coupled with his resistance to Yuma's question (It would be very risky for a scum to take this position - this isn't 100% evidence, but certainly points towards SB being a town in my eyes), I am more convinced of SB being town than I am of anyone else.
