Funny, I was just pondering MR for a good 10 minutes.
His play at EoD was good, where he was quick to shutdown BJ's claim. It seemed like he genuinely did not believe the claim.
The push on Milk is another positive. For most players I would say that should clear them but I have seen MR savagely bus teammates early and then ride the town cred to a wolf victory. So I'm cautious on that one.
The truly concerning thing with MR is the Aladeen MK. Yes, the mafia could have killed Aladeen as a setup, but it's also probable that it was a sheriff hunt. And a sheriff hunt obviously incriminates MR because Aladeen was adamant he was scum. To the point where it looked like he may have had an investigation result behind his back.
